Excellent! the title contains 1-12 words, and within 10-70 characters!
The title will be displayed in search engine results in the form of a direct link to the site.
Tips:
1. ideally, the title should contain 10 to 70 characters, including spaces. (Google displays up to 70 characters in the title, and takes into account only the first 12 words.)
2. put the most important and relevant keywords in the title, try not to repeat any word.
3. each individual page should have a unique title. |

keyword density can be used as a factor in determining whether a web page is relevant to a specified keyword or keyword phrase.
Tips:
1. the optimum keyword density to be 1.0% - 3.0%. Using a keyword more than that could be considered search spam.
2. overuse of keywords, a practice called keyword stuffing, will cause a web page to be penalized. |

| | <EM> (29) | Update (11/12/2024): New annotated version of Fig. 1 added. Corrected who the Greenland Ranch foreman was and associated correspondence. Will fix Fig. 2 (2021/2022) problem Wednesday morning.
Update (11/13/2024): Fixed Fig. 2
Fig. 1. Lower tropospheric temperature lapse rate estimated from all stations within 100 miles of Greenland Ranch, Death Valley, CA. The number of available stations for these calculations range from several in the early years to 25 or more in the later years. Here I will assume a constant lapse rate of -0.004 during the 20th Century. The 4th order polynomial fit to the data would be another way to assume how the lapse rate changes over time.
Given the few stations available in the early years, I will base the calculations that follow on an assumed lapse rate of -0.004 deg F per ft. for the first half of the record, and will assume that the observed steepening of the lapse rate after the 1980s is real, with a value of -0.0048 deg. F per ft. in the early 2020s.
Fig. 2. Daily estimated July Tmax temperatures for Death Valley N.P. from surrounding stations (blue) compared to those observed (orange, 194 ft. below sea level)
for 2021, 2022, 2023 and 2024.
Fig. 3. Daily estimated Tmax temperatures for Death Valley during 1935, 1936, 1937, 1938 from surrounding stations (blue) compared to those observed at Greenland Ranch (orange, 168 ft. below sea level) and Cow Creek (grey, 151 t. below sea level).
Fig. 4. Daily estimated Tmax temperatures for Death Valley during 1912, 1913, 1914, 1915 from surrounding stations (blue) compared to those observed at Greenland Ranch (orange, 168 ft. below sea level).
it is still 10 deg. cooler than the 134 deg. F recorded value
Fig. 5. The world record value of 134 deg. F (red) is 10 deg. F warmer than that suggested by the surrounding higher-elevations stations’ temperature variations with elevation
on July 10, 1913.
NOTE:
Since he has done extensive investigation into some implausibly hot temperatures reported in Death Valley, I asked Bill Reid to comment on my previous blog post where I maintain that the world record 134 deg. F highest recorded air temperature was likely biased warm by about 10 deg., and should not be accepted as a world record. What follows are Bill’s initial thoughts on the subject. Also, based upon his comments, I will likely update the charts found in my previous blog post with more realistic temperature lapse rate values in the early 20th Century when insufficient stations were available to determine accurate lapse rates.
(Roy’s note: The early years had very few stations within 100 miles of Death Valley, and the temperature lapse rates I computed from those few stations appear to be biased as a result. I will correct this in a future blog post, and will provide what should be better estimates of average July daily maximum Death Valley temperatures.)
Roy’s note: In my experience, unless the vegetation area is rather large, and there is almost no wind, a weather station’s daily maximum temperature will still be largely determined by air flowing from the larger-scale desert surroundings. But note… this is different from, say a poorly sited thermometer next to a brick wall or heat pump where hot air from an isolated source can elevate the daily maximum temperature recorded
Update #1 (11/8/2024): Fixed a few typos.
Update #2 (11/8/2024): For those messaging me about Furnace Creek temperatures reaching 130 deg. F in recent years, see Bill Reid’s summary of side-by-side measurements made there [and reported at an AMS meeting] showing the non-aspirated “official” equipment produces temperatures 2-3 deg. too high during light wind conditions
Update #3 (11/9/2024): Bill Reid corrected my use of the term “mountain” stations to describe those not in Death Valley. Many of those stations are at desert plateau sites, so I have changed the term to “higher elevation” stations. I have also asked Bill to provide additional thoughts on this issue, which will be the next blog post here.
tens of degrees
Yet, from a meteorological standpoint, Death Valley in the summer is the perfect place to quality check those hot temperatures from more distant, higher-elevations stations.
Fig. 1. July average maximum temperatures at stations within 100 miles of Furnace Creek, CA in 2024 (top) and 1913 (bottom), plotted against station elevation. The regression lines are fit to all stations except those near Greenland Ranch/Furnace Creek/Death Valley N.P.
Bill Reid correctly points out that in the plots which follow, the results in the early years are from very few stations, and I agree that I should probably have used regression-derived lapse rates averaged from other years with more stations.
Fig. 2. Yearly estimates of July average temperature at Furnace Creek, CA based upon all available GHCN stations within 100 miles of Furnace Creek. Each yearly estimate is based upon the station data from that year. The indicated estimate on July 10, 1913 (the date of the world record 134 deg. F reported reading) is 10 degrees cooler than the world record, at 124 deg. F. This 1-day estimate is based upon the surrounding stations only on that date. Note the 2024 value is about 0.5 deg. F above the value in 1931. Note that urban heat island effects (not accounted for here) might have biased the later half of the record to the warm side.
In simple terms, daytime temperatures during the warm season in dry, semi-desert or desert climates vary with altitude in a predictable and repeatable manner, and with little change over substantial distances.
Fig. 3. Estimated biases in the official GHCN July-average temperatures in Death Valley, CA based upon comparison to Death Valley estimates made from all stations within 100 miles of Furnace Creek. The 1-2 deg. F average bias over most of the record might well not be an actual bias in the official measurements, but instead a bias in the method described.
yet they have no way of knowing how much urbanization has contributed to those record high temperatures

search engines cannot `see` images, proper Alt content will help them to better understand and index images.
Tips:
1. always add alt attributes to images. Alt is mandatory for accessibility and for valid XHTML.
2. words used within an image`s Alt attribute should be its text equivalent and convey the same information.
3. use a human-readable caption and descriptive text around the image. |
