Hot Death Valley Days: Don’t Trust Those Temperatures
December 13th, 2024
Summary
Previous research has shown the temperatures recorded at Death Valley National Park (DVNP) have curious warm biases on very hot days, possibly due to instrument deficiencies or proximity to mounting structure apparatus and other manmade structures.
Here it is shown from 21 years of summertime (June, July, August) data that DVNP has many more days when temperatures are much higher than those at the nearby Stovepipe Wells station, than when Stovepipe Wells has hotter days than DVNP station.
These lines of evidence suggest that the hot summer daytime temperatures reported at Death Valley National Park have potentially large biases, and should only be used for their entertainment value.
In our continuing examination of the world record hottest temperature of 134 deg. F recorded at Greenland Ranch (now Death Valley National Park station) on 10 July 1913, we are finding some curious behavior in recent summertime temperatures there.
(The Bulletin of the American Meteorological Society [BAMS] has accepted my proposal for a BAMS article showing the evidence that the 134 deg. F world record was 8 to 10 deg. F higher than what actually existed on that date [10 July 1913]).
