My post on Lampasas,TX has created quite a stir when Atmoz, a climate scientist unknown person at the University of Arizona, tried to demonstrate that the temperature spike shown in the GISS data at Lampasas, TX, was not due to the relocation next to a building and asphalt parking lot, but rather some problem with […]
Pseudonymous U of Arizona climate scientist, Atmoz, has stated that the sharp increase of surface temperatures in 2000 in Lampasas TX recently reported at Climate Audit is not due to problems resulting from site relocation, but from an unidentified faulty algorithm (“UFA”) used by NASA. Atmoz stated Adjustments made by [NASA] GISS to this station […]
The http://www.surfacestations.org project continues to collect new stations, though we could certainly use more help in the midwest, particularly Kansas, Nebraska, Oklahoma, and Texas. This NOAA USHCN climate station of record #415018 in Lampasas, TX was found to be tucked between a building, and two parking lots, one with nearby vehicles. According to the surveyor, […]
HO83 ASOS Hygrothermometer (temperature/dewpoint sensor) Much has been written about problems with artificially high temperature readings due to the HO83 aspirated air temperature/dewpoint temperature sensor used on NOAA Automated Surface Observing Stations (ASOS). The most famous problem occurred in Tucson, AZ in the mid 1980’s where a malfunctioning HO83 unit created dozens of new high […]
Last summer I attempted to do a survey of Reno’s USHCN official climate station. But I was thwarted by its placement at the Reno International Airport due to security and lack of accessible photographic vantage points. Reno’s USHCN station is particularly important due to it being part of the test cases of stations in the […]
We’ve heard a lot recently from RC about whether solar can account for temperature variations in the 20th century. While my primary interest in these ruminations is the possibility of pinning down a set of standards by which they agree that a study is “bad” – since it’s hard for me to determine any sins […]
You may recall the post earlier this year where the USHCN official climate station with the largest positive trend in the USA turned out to be located in a parking lot at the University of Arizona in Tucson. See below: Click picture to see image gallery at surfacestations.org The GISS surface temperature plot for Tucson: […]
There’s a USHCN station out there, in the “ass end of nowhere”. Apologist Eli Rabett (Joshua Halpern) recently lamented that in order for dendrochronologists to update tree ring studies used in MBH98/99 (aka Mann’s Hockey Stick) that they “have to drive out to the ass end of nowhere”. It’s such an inconvenience for those that […]
In order to assess the 2006 anomaly in John V’s 2006 calculation reported previously, I’ve calculated a gridded anomaly for the U.S. using standard spatial smoothing software in R. This enables the calculation to be done in a few lines as explained below. I’ll also show results which reconcile most of the results to date. […]
