\u00a0Of course. \u00a0I did the same back in the mid-1980s when I was doing research for my <a href=\"http:\/\/stormbruiser.com\/chase\/a-critical-analysis-of-eastern-mojave-desert-temperatures-by-william-t-reid\/\">Masters Thesis (&#8220;A Critical Analysis of Eastern Mojave Desert Temperatures&#8221;).<\/a> \u00a0I drove about and took temperature readings with a psychrometer thermometer &#8212; the kind one spins to get a dry bulb and wet bulb temperature reading. \u00a0Some of these observations are provided in the Appendix section of my thesis.<\/p>\n<p>&nbsp;<\/p>\n<p>I am currently working on a paper to show that the record maximum temperature of 134F in Death Valley in 1913 is bogus. \u00a0This high temperature is officially the world record high temperature. \u00a0 But, I am convinced that the figure was artificially and inappropriately augmented, or &#8220;jacked up&#8221; somehow, by the station observer way back then. \u00a0A temperature that hot is not supported by the maximum temperatures at the same time at other stations in the region.\u00a0 For more information on this study, see my article in this <a href=\"https:\/\/www.wunderground.com\/blog\/weatherhistorian\/an-investigation-of-death-valleys-134f-world-temperature-record.html\">Weather Underground blog with Chris Burt.<\/a>\u00a0 Naturally, a better understanding of how ambient air temperature behaves in and around Furnace Creek on typical, hot summer afternoons should aid in understanding why and how the 134F reading came to be, and why it can not be valid.<\/p>\n<p>So, part of the purpose of this trip was to get out to Death Valley and the Furnace Creek Ranch area on a very hot day, and to check my thermometer readings against those at the official station. \u00a0I also wanted to check around the ranch for other thermometers and to see what those were reading during the hottest part of the afternoon. \u00a0The official Death Valley temperature measurements are (currently) made at the weather station that was set up just NNW of the Visitors Center in 1961. \u00a0Back in 1913, two years after the U.S. Weather Bureau first set up a cooperative station (called &#8220;Greenland Ranch&#8221;), the instruments were placed above &#8220;cultivated&#8221; land, where extensive irrigation was in use. \u00a0(This was about a quarter-mile south of the current station site.) \u00a0Furnace Creek Ranch\/Greenland Ranch is, and has been, an oasis area with a variety of different ground covers, and with an assortment of buildings and vegetation which have significant effects on the local temperature patterns on sunny summer days. \u00a0Today, I wanted to document the temperature differences and patterns around Furnace Creek. \u00a0It is not an official study, but the results should give one a good idea of how different areas of the ranch and oasis compare. \u00a0 I think it is important because my hypothesis is that the observer in 1913, Oscar Denton, felt some compunction to artificially and inappropriately &#8220;jack up&#8221; the official readings during a heat wave during the first two weeks of July, 1913. \u00a0The short version of my theory: \u00a0In the decades leading up to the establishment of the new USWB weather station at Greenland Ranch in 1911, it was a widely-held belief that temperatures in Death Valley soared easily into the 130s on the hottest summer afternoons. \u00a0It might even touch 140F, according to some reports. During a very hot stretch during the second week of July, 1913, Denton was getting official measurements of maximum temperatures which seemed, in his mind, to under-represent the true high temperatures, or the true nature of the hot weather in Death Valley. \u00a0So, he changed the readings from the standard instruments (that were likely in the mid-120s) to values that he thought were more accurate, or more representative. \u00a0 Denton&#8217;s entries from July 7 to July 14, 1913, included several maximums of 127F to 129F and entries of 130F, 131, and 134F. \u00a0Greenland Ranch had no maximums as high as 130F at any other time during its period of record from 1911 to 1960. \u00a0While Denton likely knew that what he was doing went against protocol, he might have convinced himself that his actions were appropriate, or necessary, since the official station measurements were too low.<\/p>\n<p>Southern California and Nevada were under the influence of an upper-level high pressure system on July 23, 2017. \u00a0It wasn&#8217;t the mega-strong type of upper high that produces near-record summer heat in the desert areas, but it was medium-strong by mid-summer standards. \u00a0There was the typical moderate onshore flow at the surface along the California coastline to inland areas, with a thermal low hanging out around Needles, as usual. \u00a0Surface flow was weak in the Death Valley region. \u00a0Low-level moisture was minimal-to-moderate, with dew points generally in the 40s to maybe low 50s (F) in the southern reaches. \u00a0A surge of monsoonal moisture from the southeast was expected the next day, but today there wasn&#8217;t enough moisture to cause more than a few mid-level clouds and some very high-based flat cumulus over the highest mountains during the afternoon convection. \u00a0Thus, for the bulk of the region on this afternoon, the skies were bright and sunny and winds were generally light. \u00a0At the bottom of this paper I include a bunch of regional weather data to look over if you are interested. \u00a0Below are the hourly observations by the NWS automatic instrumentation in the Furnace Creek weather station corral (at the National Park Service Visitors Center):<\/p>\n<p>&nbsp;<\/p>\n<p><a href=\"http:\/\/stormbruiser.com\/chase\/wp-content\/uploads\/2017\/07\/Furnace-Creek-hourlies.pdf\">Furnace Creek hourlies<\/a><\/p>\n<p><strong>23 July 2017<\/strong><\/p>\n<p><strong>PDT \u00a0Temp\/Dew Pt \u00a0Wind<\/strong><\/p>\n<p>0500 \u00a0 101\/41 \u00a0S4 G7<\/p>\n<p>0600 \u00a0 98\/40 \u00a0E4<\/p>\n<p>0700 \u00a0 98\/43 \u00a0NW2<\/p>\n<p>0800 \u00a0102\/48 \u00a0Calm<\/p>\n<p>0900 \u00a0106\/48 \u00a0SE3 G6<\/p>\n<p>1000 \u00a0109\/46 \u00a0ESE4 G6<\/p>\n<p>1100 \u00a0112\/46 \u00a0SE2 G5<\/p>\n<p>1200 \u00a0115\/49 \u00a0SE1 G5<\/p>\n<p>1300 \u00a0116\/44 \u00a0WNW4 G5<\/p>\n<p>1400 \u00a0119\/46 \u00a0S2 G6<\/p>\n<p>1500 \u00a0120\/44 \u00a0SE5 G7<\/p>\n<p>1600 \u00a0121\/47 \u00a0SSW3 G7<\/p>\n<p>1700 \u00a0122\/49 \u00a0S4 G7<\/p>\n<p>1800 \u00a0121\/48 \u00a0SW5 G7<\/p>\n<p>1900 \u00a0119\/49 \u00a0S3 G6<\/p>\n<p>2000 \u00a0114\/48 \u00a0SE2 G5<\/p>\n<p>2100 \u00a0114\/50 \u00a0S3<\/p>\n<p>2200 \u00a0109\/48 \u00a0WSW3 G4<\/p>\n<p>2300 \u00a0110\/52 \u00a0WSW2 G4<\/p>\n<div class=\"page\" title=\"Page 2\">\u00a02400 \u00a0108\/53 \u00a0SE5<\/div>\n<div class=\"page\" title=\"Page 2\"><\/div>\n<div class=\"page\" title=\"Page 2\"><\/div>\n<div class=\"page\" title=\"Page 2\">All temperatures here are in degrees F, and the wind speeds are in mph units. \u00a0For time of day I will stick to the local time\/PDT. \u00a0 To convert to standard time, subtract one hour.<\/div>\n<p>The official maximum temperature for the day was <strong>123F<\/strong> here at the Death Valley weather station. \u00a0It likely occurred close to 5 p.m. PDT (4 p.m. PST), when the hourly observation was <strong>122F<\/strong>. \u00a0The official low temperature on the 23rd was <strong>97F<\/strong>, and the morning low temperature on the 24th was a toasty <strong>100F<\/strong>. \u00a0The maximum of 123F is about 6-7 degrees <strong>above<\/strong> the normal average maximum temperature for July, and it is about 6 degrees <strong>below<\/strong> the reliable all-time record maximum temperature of 129F at the station. \u00a0(I would postulate that this day was likely some 3-4 degrees cooler than conditions on July 10, 1913, when a maximum of 134F was recorded by Denton.) \u00a0 The hourly march of temperatures on July 23 at Furnace Creek was very typical for a day of this type. \u00a0The temperature rose gradually and steadily from 7 a.m. to noon, increasing about four degrees each hour. \u00a0The temperature continued to rise during the early afternoon, but at a slower rate.<\/p>\n<p>(Meteorological lesson: \u00a0By about 2 or 3 p.m. PDT, the lower atmosphere had &#8220;mixed out&#8221; entirely. \u00a0This implies that there was full convection from the surface to about 15,000 feet above sea level in the region, and environmental lapse rates were near or at the dry adiabatic lapse rate. \u00a0When this occurs, the surface temperature is at its &#8220;upper limit.&#8221; \u00a0Though the temperature may creep up a little more into the mid-late afternoon, there can be, generally speaking, no additional significant increase in the ambient air temperature because that would require a similar increase in temperature of the entire air mass from the surface to levels up to 15,000 feet or thereabouts. \u00a0Once the atmosphere has &#8220;mixed out&#8221; and reached its upper-limit temperature, the ambient air temperature tends to remain within a couple of degrees of the day&#8217;s maximum temperature for about four hours.)<\/p>\n<p>The hourly temperatures at Furnace Creek ranged from <strong>119F to 122F<\/strong> from 2 p.m. to 7 p.m. PDT. \u00a0Sunset is around 8 p.m. PDT, and temperature was <strong>114F<\/strong> at that time. \u00a0It was still a hot <strong>110F<\/strong> at 11 p.m. PDT. \u00a0The wind was mostly light at the station for the entire day, with average speeds of 5 mph or less. \u00a0Once the atmosphere had mixed out in the afternoon, the wind had a southerly component. This, again, is very typical at Furnace Creek on hot summer afternoons. \u00a0 The screaming message here is this: \u00a0July 23, 2017, was a very typical hot summer day in Death Valley and in the region as a whole. \u00a0 Conditions on this day (sunshine, wind, humidity, hourly march of temperature, etc.) were likely very similar to conditions experienced on most of the very hottest of summer days at Furnace Creek in the past 100 years and more. \u00a0Add about 5-6 degrees (F) to the temperatures below, and you will have a very good estimate of what the temperature will be during the afternoon in various locations at the given times on the hottest days on record in the region.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>TEMPERATURE MEASUREMENT<\/strong><\/p>\n<p>The temperature measurements for this study were made with my plastic handheld Kestrel weather instrument. \u00a0It measures wind, temperature, and humidity. \u00a0The temperature sensor is quite sensitive and the instrument gives readings to the nearest tenth of a degree. \u00a0While driving, I would roll down the driver-side window and hold the Kestrel outside and into the wind as far forward as I could reach, so that air inside the vehicle was not be affecting the reading. \u00a0Typically, the temperature readouts would vary quite a bit over the course of a 10-20 second &#8220;measurement&#8221; while moving at about 60 mph. \u00a0Temperature would commonly vary by 3 to even 4 degrees (F) or so. \u00a0This variance is due to the normal character of the desert atmosphere on sunny summer days, and the sensor&#8217;s high sensitivity and quick reaction time. \u00a0On sunny days, local mini-hotspots form above the desert surface amid the not-so-hotspots, according to terrain and wind for the most part. \u00a0Localized sunlit areas in calm or weak winds tend to warm a little more (by just a couple of degrees F) than nearby areas where the wind might be a little stronger or the ground surface a little different, and the air near the surface a bit more mixed. \u00a0We are talking areas separated by perhaps 25-to-50 meters, more-or-less!<\/p>\n<p>So, again, the instrument typically showed temperature ranging over a 3-4 degree spread for a 10-20 second measurement period while driving. \u00a0If the range was from 100F to 102F, then I would give that measurement a value of 101F. \u00a0If the spread was 99F to 102F, then I would give it a 100F. \u00a0Even if it was a slightly larger range, such as 98F to 102F, then I would write down a 99F temperature. \u00a0I wanted to be conservative on every measurement.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><strong>THE DRIVE &#8212; Mojave area<\/strong><\/p>\n<p>I left home around 8 a.m. and reached Mojave about 90 minutes later. \u00a0At 10 a.m., eight miles north of Mojave (elevation about 2400 feet), the temperature was <strong>94F<\/strong>. \u00a0Interestingly, about 15 minutes later and about 500 feet lower, along the north edge of Koehn Dry Lake, the temperature reading was <strong>92F.<\/strong> \u00a0Presumably, mid-morning mixing was still relatively weak in the Koehn basin. \u00a0 The cooler (and heavier) surface and near-surface air associated with the nighttime radiation inversion had yet to mix out fully. \u00a0It would later in the day, of course, as the sun got higher in the sky and the wind increased. \u00a0Just down the road, at Garlock (elev. 2150 feet), it was <strong>95F<\/strong> at 10:26 a.m.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Trona area<\/strong><\/p>\n<p>Skies continued to be very clear and the sunshine very bright on the way from Garlock to Trona. \u00a0 The wind was light. \u00a0I was on U.S. 395 for a few miles, and then turned northeast on Searles Station Cutoff Road. \u00a0The intersection of the two is near the top of a ridge. I measured <strong>93F<\/strong> here at 10:36 a.m., elevation about 3400 feet. \u00a0There is another ridge along Trona Road, southeast of Ridgecrest, and it was <strong>97F<\/strong> here at 10:52 a.m. (about 3300 feet). \u00a0Trona Road then descends to Highway 178, east of Ridgecrest. \u00a0Here, near 2040 feet in elevation, the temperature was <strong>101F<\/strong> at 11 a.m.; at 11:07 a.m. it was <strong>99F<\/strong> at the turnoff to the Trona Pinnacles (elev. about 1650 feet). \u00a0Again, the cooler air in the desert basins (comparably) indicates that some heavier nighttime air still lingered late morning. \u00a0I took a break in Trona, and my next reading was at 11:50 a.m. on the north side of town, at Pioneer Point: \u00a0<strong>102F<\/strong> (1675 feet). \u00a0Though Trona-Wildrose Road ascends to the pass to the Panamint Valley at close to 3000 feet elevation, more than 1000 feet higher than Trona and Searles Lake, the temperature was only a degree cooler (<strong>101F<\/strong>) at 12:03 p.m.<\/p>\n<p>&nbsp;<\/p>\n\n\t\t<style type=\"text\/css\">\n\t\t\t#gallery-2 {\n\t\t\t\tmargin: auto;\n\t\t\t}\n\t\t\t#gallery-2 .gallery-item {\n\t\t\t\tfloat:

of the Panamint Valley&#8217;s southern dry lake, taken from the pass between the Panamint Valley and the Searles Valley along Trona-Woldrose Road. \u00a0The dirt road across the dry lake to Ballarat is visible. \u00a0Some flat cumulus clouds were above Telescope Peak and the Panamint Range by about noon. \u00a0These were not able to develop much vertically during the afternoon. \u00a0Dew points in Death Valley and Panamint Valley were around 50F on this afternoon, and cloud bases were probably around 14,000 to 15,000 feet above sea level.<\/em><\/p>\n<p>About 15 miles north of here, Trona-Wildrose Road veers off to the northeast into Wildrose Canyon, and Panamint Valley road continues northward into the northern portion of Panamint Valley. \u00a0The route into Wildrose Canyon was closed due to old flood damage to the road. \u00a0The elevation at the intersection is 1320 feet and the temperature at 12:27 p.m. was <strong>108F<\/strong>. \u00a0Thirteen minutes later, at 12:40 p.m. and two miles south of Highway 190 at 1540 feet elevation, temperature was <strong>110F<\/strong>. \u00a0By this time the sun was nearing its highest point in the sky for the day and the lower half of the troposphere was mixing strongly &#8212; not quite to the &#8220;upper limit&#8221; temperature for the day yet, however! \u00a0This location is near the dry lake in the northern part of Panamint Valley. \u00a0The lake bottom here is at about 1535 feet, nearly 500 feet above the lower dry lake to the south (near Ballarat). \u00a0I measured<strong> 108F<\/strong> at 12:50 p.m. on the

intersection of Panamint Valley Rd. and Highway 190 in Panamint Valley. \u00a0Panamint Springs is a few miles west of here, and the dry lake is nearby to the east. \u00a0The elevation is about 1540 feet and the ground cover is very sparse. \u00a0The view is to the east in Figure 3 and to the north in Figure 4, towards the Panamint Dunes (visible in the distance).\u00a0<\/em><\/p>\n<p>From the dry lake the road steeply climbs into the Panamint Range towards Death Valley. \u00a0I measured <strong>107F<\/strong> at the 2000-foot sign at 12:53 p.m., <strong>104F<\/strong> at 3000 feet at 12:56 p.m., and <strong>98F<\/strong> at 4000 feet at 12:59 p.m. \u00a0Three minutes later (at 1:02 p.m.) I had reached Towne Pass at 4956 feet, and the temperature was a rather refreshing <strong>92F<\/strong>. \u00a0Here at the pass it was about 17 degrees cooler than the dry lake in Panamint Valley along Highway 190, 3420 feet lower in elevation.<\/p>\n<p>Regional temperatures at 1 p.m. were 102F at Lancaster (wind SW 20 mph), 102F at Edwards (wind SW 9 mph), 106F at China Lake (wind S 10 mph), 116F at Death Valley\/Furnace Creek, and 102F at Bishop (S 12 mph). \u00a0Towne Pass, about 5150 feet above Furnace Creek, was 24 degrees cooler than that Death Valley locale at 1 p.m.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Death Valley\/Stovepipe Wells area<\/strong><\/p>\n<p>In the early afternoon hours on sunny summer days such as today, the desert atmosphere is nearing the point of full mixing to heights up to three miles above the desert basins. \u00a0Typically the low-level air is in motion and a breeze with a speed of 5-10 mph is blowing. \u00a0 It is not unusual to see dust devils on the desert flats and alluvial fans. \u00a0The relatively cool air that pooled in the basins at night is mixed out entirely, or nearly so. \u00a0The lower atmosphere is mixed sufficiently so that air warms and cools at a rate of about 5 degrees F\/1000 feet, or slightly less steep than the dry adiabatic lapse rate (of 5.4 degrees F\/1000 feet). \u00a0By about 2:30 p.m. PDT on days such as today, with full and bright sunshine, full mixing is in progress and the ambient temperature is near or at its upper limit. \u00a0One would not expect the high temperature for the day to get more than 2-to-3 degrees (F) hotter than the readings reached by 2:30 p.m. PDT.<\/p>\n<p>Highway 190 descends rapidly in elevation from Towne Pass to Stovepipe Wells, which is very close to sea level in Death Valley. \u00a0Here are the times and temperatures along 190:<\/p>\n<p>Towne Pass\/4956 feet \u00a0<strong>92F<\/strong>\/1:02 p.m.<\/p>\n<p>4000 feet \u00a0<strong>99F<\/strong>\/1:07 p.m.<\/p>\n<p>3000 feet \u00a0<strong>102F<\/strong>\/1:09 p.m.<\/p>\n<p>2000 feet \u00a0<strong>108F<\/strong>\/1:13 p.m.<\/p>\n<p>1000 feet \u00a0<strong>113F<\/strong>\/1:17 p.m.<\/p>\n<p>St. Wells\/5 feet \u00a0<strong>119F<\/strong>\/1:21 p.m.<\/p>\n<p>Temperature increased by 27 degrees in the 20 minutes from Towne Pass to Stovepipe Wells. \u00a0Elevation change was 4950 feet.<\/p>\n<p>I spent some time taking readings with the Kestrel thermometer from about 1:30 to 1:35 p.m. in front of the Stovepipe Wells General Store. \u00a0Readings in the shade of the building ranged from <strong>117F to 121F<\/strong> for the most part. \u00a0It seemed that the temperature was more apt to rise when the breeze kicked up. \u00a0At the nearby Ranger Station, where an old thermometer shelter still stands, I measured <strong>119F<\/strong>. \u00a0The Kestrel showed a dew point in the upper 50s (though on dew point it reads about five degrees too high), and some flat cumulus clouds were forming over the highest elevations of the Panamint Range. \u00a0There were quite a few people milling about outside at Stovepipe Wells. \u00a0It seems that many people, especially from Germany and other European countries, now choose Death Valley as a mid-summer destination in order to experience such hostile conditions&#8230;at least for an afternoon! \u00a0Thirty years ago, when I visited Death Valley in the summer a few times, there would be very few visitors out and about during the early afternoon.<\/p>\n<p>&nbsp;<\/p>\n\n\t\t<style type=\"text\/css\">\n\t\t\t#gallery-5 {\n\t\t\t\tmargin: auto;\n\t\t\t}\n\t\t\t#gallery-5 .gallery-item {\n\t\t\t\tfloat:

time, and it was somewhat of a relief that I did not see anyone headed towards the dunes in the background. \u00a0Figure 12 shows the salty playa of Death Valley between Stovepipe Wells and Furnace Creek. \u00a0The view is to the southwest. \u00a0The ruins of the Harmony Borax Works are in Figure 13. \u00a0The last two images are at the fuel and service station in Furnace Creek. \u00a0A round thermometer showed a temperature of 111F, which was surprisingly low given the readings near 120F at Furnace Creek at the time AND the air conditioning unit right above it!<\/em><\/p>\n<p>&nbsp;<\/p>\n<p>The next stop was the Death Valley National Park Service Visitors Center. \u00a0This area is on the north side of the &#8220;ranch,&#8221; on the west side of the highway, northeast of a golf course, and south and east of generally open and undeveloped and barren desert. \u00a0An area for camping and RVs is just northwest of the Visitors Center, but it is generally empty in summer.<\/p>\n<p>&nbsp;<\/p>\n<p>I measured <strong>120F<\/strong> along 190 near the Visitors Center at 2:40 p.m., and then <strong>120F<\/strong> at 2:42 p.m. around the fenced weather station &#8220;corral&#8221; (which is perhaps 120 feet NNW of the main building of the Visitors Center). \u00a0The official elevation for the weather station is -194 feet. \u00a0About eight minutes later, at 2:50 p.m. PDT, I was measuring temperatures averaging <strong>121F to 122F<\/strong> at the weather station site. \u00a0The wind at this time was fairly light, from the south at

style='clear: both' \/>\n\t\t<\/div>\n\n<p>&nbsp;<\/p>\n<p><em>Figures 16 to 22 (above): \u00a0The official National Weather Service and National Park Service cooperative weather station at Furnace Creek in Death Valley, July 23, 2017. \u00a0(The station name is &#8220;Death Valley.&#8221;) \u00a0The instruments are above bare ground and are approximately 40-50 meters NNW of the visitor center buildings. \u00a0 A covered parking area is only 15 to 20 meters to the east.<\/em><\/p>\n<p><em>Figure 16 is a look to the southeast, towards the visitors center. \u00a0The mostly bare ground near and around the weather station promotes hotter temperatures on sunny afternoons. \u00a0Since the wind on summer afternoons is usually from the south, the brush and the trees and the structures to the southwest, south, and southeast of the station would cause poorer ventilation through the weather station and would also promote higher temperatures there on sunny afternoons.<\/em><\/p>\n<p><em>Figure 17 is the view from the southeast corner of the fenced enclosure, looking to the northwest. \u00a0The old CRS (cotton region shelter) is the louvered wooden box in the far (northwest) corner of the fenced enclosure (aka the weather station &#8220;corral&#8221;). \u00a0Just to the south of the shelter, on the tall pole, is the newer National Weather Service instrumentation. \u00a0This instrumentation measures (electronically) rainfall, wind, and temperature\/humidity; it provides the &#8220;official&#8221; temperatures (the daily maximums and minimums) for the station. \u00a0 Visible in this view (and other views here), and associated with this electronic instrumentation are the rain gage, the wind vane and anemometer, the thermometer radiation shield, and a solar panel and a transmitting antenna. \u00a0 The current data are transmitted to a satellite and then to the NWS in Las Vegas. \u00a0The Park Service staff (still) take daily max and min temperature readings at about 8 a.m. every day from the thermometers inside of the shelter. \u00a0According to the Park Service, the temperature readings between the newer electronic station and the older CRS instrumentation are close; they notify the NWS in Las Vegas if they notice any unusual variance. \u00a0To the east of the CRS is an automatic rain gage that is surrounded by a ring of silver &#8220;slats&#8221; which help to reduce the wind around the gage, in order to promote a better and more accurate catch of any rainfall. \u00a0This rain gage instrumentation was set up recently by a hydrologist to compare rainfall catches between it and the standard 8-inch rain gage (the dark brown gage right next to it). \u00a0Also visible in Figure 17 is a wooden pallet, flat on the ground in the middle of the corral. \u00a0Large evaporation pans, to measure evaporation loss, would rest on a pallet such as this, but the evaporation pan which was in use for decades is no longer here. \u00a0On the extreme left side of Figure 17 is another cotton region thermometer shelter, on the ground and not in use. \u00a0In the foreground is a garden hose and faucet, presumably for re-filling the evaporation pan when it was in use.<\/em><\/p>\n<p><em>In Figure 18 the view is to the NNW from the south side of the weather station corral. \u00a0A Davis Vantage Pro 2 weather station is in the foreground at the top of the image. \u00a0The data from this station are sent electronically to a display in the nearby visitors center. \u00a0I operate several of these weather stations, and have found the temperature measurements from them to be quite accurate and reliable.<\/em><\/p>\n<p><em>The view in Figure 19 is from the north side of the corral, looking to the SSE. \u00a0The &#8220;front&#8221; of the CRS is in the foreground. \u00a0The shelter door opens on this side, and it is always facing to the north. \u00a0In the far corner of the corral is the Davis station. \u00a0On the left side of this image is the nearby covered parking area for the Park Service employees, and a white energy storage tank.<\/em><\/p>\n<p><em>Figure 20 shows my handheld Kestrel instrument which I was using for temperature measurement this day. \u00a0View to the south.<\/em><\/p>\n<p><em>Figure 21 is a better view of the station and the vegetation and structures to its south.<\/em><\/p>\n<p><em>And the last of the images above, Figure 22, shows some air conditioning\/cooling equipment, presumably. \u00a0This machine is also visible in the background of the previous photo. \u00a0The brick wall around the &#8216;Evapco&#8221; equipment is between 6 and 7 feet high, and no doubt helps to diminish the strength of southerly breezes through the weather station area. \u00a0Does this equipment emit hot air when it is functioning? \u00a0I do not know.<\/em><\/p>\n<p>&nbsp;<\/p>\n<p>My Kestrel indicated <strong>120F<\/strong> above the sidewalk on the south side of the Visitors Center, along the public parking area. \u00a0At the same time, the digital thermometer that the Park Service has near the front entrance of the Visitors Center building showed 127F. \u00a0This relatively new digital thermometer display is generally a &#8220;photo op&#8221; provided for Death Valley tourists. \u00a0It read 126F to 127F at 2:41 p.m. and 127F at 2:57 p.m., or an easy 5-to-7 degrees higher than the temperatures that I was getting off of my Kestrel. \u00a0This was in bright sunshine above bare ground with light wind.<\/p>\n<p>&nbsp;<\/p>\n\n\t\t<style

\u00a0Every visitor to the visitor&#8217;s center walks right by this relatively new addition to the center! \u00a0Graphics on the metal display provide the elevation here (-190 feet) and a scale to convert Fahrenheit to Celsius. \u00a0A representative for the Park Service told me that she was aware that this exhibit showed hotter temperatures than the official instruments (in the corral behind the visitors center), but that &#8220;the tourists love it!&#8221; \u00a0The display&#8217;s sensor is somewhere inside of this metal housing, so it is not surprising that the temperatures provided are on the hot side when the thing is in bright sunshine.<\/em><\/p>\n<p>&nbsp;<\/p>\n<p>Regional Temperatures at 3 p.m. PDT:<\/p>\n<p>Lancaster 101F\/SW 21 mph<\/p>\n<p>Edwards \u00a0104F\/SW

hottest part of the afternoon. \u00a0In summer at Furnace Creek, daytime high temperatures generally occur between about 4 and 5 p.m. PDT (or between 3 and 4 p.m. PST). \u00a0 The temperature is typically within a couple of degrees of the day&#8217;s maximum temperature from about 2:30 to 6:30 p.m PDT (or from about 1:30 to 5:30 p.m. PST). \u00a0I wanted to compare Kestrel readings above different ground surfaces at the ranch, so I parked by the Death Valley golf course store. \u00a0 \u00a0This is on the northeast corner of the golf course. \u00a0I measured <strong>118F<\/strong> adjacent to the golf course store, near some shady areas by some trees. \u00a0On the golf course itself, on the grassy fairway some 20 yards or so from the golf course store, the temperature was about <strong>116F to 117F<\/strong>. \u00a0These readings were taken in the sun around 3:02 to 3:07 p.m. PDT. \u00a0The wind was light, but as is the case on most summer afternoons, was out of the south. \u00a0Thus, the air had been moving over the moist and grassy golf course for a little while and had cooled due to evaporative cooling effects. \u00a0The temperature above the fairway in the northeast corner of the golf course was about 3 to 5 degrees cooler than that around the Visitors Center, only 100 meters or so to the north. \u00a0The round thermometer on the wall of the golf course store, in the shade, read 123F.<\/p>\n<p>&nbsp;<\/p>\n\n\t\t<style type=\"text\/css\">\n\t\t\t#gallery-10 {\n\t\t\t\tmargin: auto;\n\t\t\t}\n\t\t\t#gallery-10 .gallery-item {\n\t\t\t\tfloat:

west-side wall, under the eave. \u00a0It was reading about 5 degrees warmer than the temperatures I was seeing off of the Kestrel in front of the store (perhaps due to the nearby hot pavement and poor ventilation as the sun was coming around to the west, and\/or perhaps because this household instrument was poorly calibrated). \u00a0Figures 28 (to the southwest) and 29 (view to the east) show a pole with weather instruments on the southeast corner of the golf course store. \u00a0I spoke with an employee at the store, and we determined that the station failed a year or two ago, and the weather display console which was behind the cash register desk was removed. \u00a0Someone had been called to try to fix the station, but that someone never got around to looking into the problem. \u00a0It would be interesting to compare readings from a station such as this to the data from the official weather station at the visitors center. \u00a0 In Figure 30, the Kestrel shows a temperature of 116.6F above the nearby grassy fairway. \u00a0This view is to the southwest.<\/em><\/p>\n<p>At 3:10 p.m. the temperature along 190 at the entrance to the ranch was<strong> 119F.<\/strong> \u00a0A little farther to the south, at the road to the Indian village, it was <strong>120F<\/strong>. \u00a0At 3:12 p.m. the temperature averaged about <strong>121F<\/strong> along Indian Village Road, south of the ranch. \u00a0There is little or no evaporative cooling effects here, south of the ranch, and the temperature on the Kestrel briefly showed <strong>124F<\/strong>. \u00a0At 3:15 p.m., back at the entrance to the ranch, the temperature was averaging about <strong>118.5F<\/strong>. \u00a0The round thermometer on the sign at the ranch entrance showed 111F. \u00a0It was in the shade. \u00a0Another round thermometer, under the eave of the nearby general store, showed 117F. \u00a0 My Kestrel showed the same in this shady area. \u00a0I parked the vehicle and walked around the roadways and buildings in the main Furnace Creek ranch\/motel area. \u00a0Here are the times and temperatures:<\/p>\n<p>3:20 p.m.\/<strong>120F<\/strong> \u00a0parking area in front of post office<\/p>\n<p>3:22 p.m.\/<strong>120F<\/strong> \u00a0in front of office buildings just SW of Borax Museum (Taylor Digital thermometer on outside office wall, north side, showed 127F)<\/p>\n<p>3:30

showing a reading close to 130F at that time. \u00a0The third photo in the group above shows the thermometer that was under the eave of the general store, and well protected from the effects of direct

\u00a0A Taylor digital thermometer that was attached to the wall indicated a temperature of 127.9F, even though it was in the shade. \u00a0This was seven degrees or more hotter than the temperature of the ambient air. \u00a0The final two images show two of my personal household thermometers, brought to Death Valley for this trip. \u00a0I placed each on a fence post near a parking lot at the ranch.

temperature at the nearby weather station for the day was only 123F.<\/em><\/p>\n<p>My observations suggest that the weather station area is among the warmest spots in and around the Furnace Creek Ranch area, though the open and barren area towards the Indian village may be a degree or so hotter still. \u00a0The ranch area itself, around the buildings and parking areas, was generally a degree or two cooler than the readings I was getting near the official weather station. \u00a0I attribute this to the nearby golf course and irrigated trees and vegetation in the developed &#8220;ranch&#8221; area. \u00a0The weather station is rather close to the cooling effects of the golf course, but the typical breeze from the south through the weather station area skirts by the golf course on the east side. \u00a0 So, the golf course probably has little effect on the official station on\u00a0most afternoons. \u00a0It seemed that the areas above pavement at the ranch were no warmer than the barren areas just outside of the ranch, despite the darker nature of the pavement\/asphalt.<\/p>\n<p>The well-watered golf course area (on the fairway) was a good 3-to-5 degrees cooler than the weather station readings. \u00a0Household-type thermometers in the ranch area varied quite a bit in their readings, from about 8 degrees (F) too cool to about 8 degrees (F) too warm. \u00a0The readings that I took off of the Kestrel near the Death Valley weather station matched closely to the hourly readings from the NWS instruments. \u00a0As would be expected, heavily shaded areas at the ranch were cooler by a few degrees compared to areas in bright sunshine.<\/p>\n<p>It should be obvious (hopefully!) that local mid-afternoon desert temperatures are affected to a significant degree by the presence of structures and differences in ground cover, in an oasis settlement such as Furnace Creek. \u00a0This is, in large part, because the very dry desert air reacts quickly and significantly to changes in radiation and moist surfaces. \u00a0Well-irrigated areas, such as golf courses and grassy fields, are typically several degrees cooler than nearby open areas with a natural (mostly barren) surface. \u00a0Also, \u00a0trees, shrubs, fences, vehicles and structures can slow the wind and reduce low-level mixing locally, allowing some spots downwind (that are above barren ground) to be up to a few degrees hotter in the afternoon sunshine comparably.<\/p>\n<p>When siting a weather station in a desert area or in a desert town, an area with good ventilation and exposure to the wind, as far from buildings as possible, is important. \u00a0Presuming that we want to be able to compare weather records over time without having to adjust or note for changes in exposure and land use and ground cover, it is best to locate weather stations over natural ground cover, and in an area not likely to experience significant changes in ground cover in the foreseeable future.<\/p>\n<p>&nbsp;<\/p>\n\n\t\t<style type=\"text\/css\">\n\t\t\t#gallery-13 {\n\t\t\t\tmargin: auto;\n\t\t\t}\n\t\t\t#gallery-13 .gallery-item {\n\t\t\t\tfloat: left;\n\t\t\t\tmargin-top:

Pro 2 station in the weather station corral behind the visitors center (see Figure 18). \u00a0Interestingly, the first exhibit in this group (Figure 39) notes that &#8220;large expanses of lawn&#8221; were removed with the renovations in 2012. \u00a0This would decidedly promote a change to warmer maximums at the official Death Valley weather station. \u00a0I noted in my Master&#8217;s Thesis (back

development and vegetation growth through the years have slowed the wind and ventilation through the weather station, likely resulting in some increase in measured maximum temperatures. \u00a0There are two new pieces of equipment that are less than 25 meters south of the weather station. \u00a0A brick wall has been built on the east, south, and west sides of each one. \u00a0These may be part of the air conditioning system for the visitors center. \u00a0In Figure 44, the weather station is visible in this view to the NNW, from the east side of the northern-most &#8220;cage.&#8221; \u00a0Figure 45 is a look inside this cage from its north side. \u00a0Figures 46 and 47 are looks inside the southern-most cage, again on the north side (see also Figures 21 and 22). \u00a0 The final three images above are looks at the Visitors Center from a small hill, looking southwest. \u00a0The final two are cropped versions of the wide-angle view, showing the Visitors Center area and the nearby vegetation. \u00a0The weather station instruments are hidden by trees (below).<\/p>\n<p>&nbsp;<\/p>\n<p><a
