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.
Adjustments made by [NASA] GISS to this station seem to add an artifact that shows spurious warming since the year 2000.
The GISS temperature for this station has clearly “hockey-sticked” since the year 2000. I do not know the cause of this. But it is clearly a problem / feature of their algorithm and not an artifact in the data due to a station move.
“Amateur” reports on the Lampasas station had previously attributed the sudden increase in temperatures in 2000 to a station relocation from a park-like location to its present location surrounded by asphalt and a west-facing brick building. Atmoz rejects this explanation, saying that the amateurs failed to consider the possibility of a UFA.
Atmoz also reported the discovery of a USHCN station in Montana that is not located in a parking lot and that appears to comply with all WMO standards. Atmoz speculated that this news of contact with a USHCN station meeting all known WMO standards would not be reported at Climate Audit.
A Climate Audit spokesman said that they also welcomed the exciting news of contact and that they would immediately announce contact to their readers. He added that he was skeptical of Atmoz’ hypothesis that the Lampasas events were connected to another UFA at NASA, saying that other explanations still needed to be assessed.
A NOAA spokesman said that the agency had concerns about the news of contact and had already prepared contingency plans, including the potential relocation of the station to a nearby parking lot in Miles City, Montana shown in the picture below.
Atmoz is located in Tucson, Arizona, which pioneered the establishment of weather stations in parking lots long before Lampasas TX. Atmoz’ office overlooks the U of Arizona parking lot that hosts the weather station that has the highest temperature trend increase in the entire US Historical Climatology Network. Tucson is located in southern Arizona, approximately 350 miles to the west of Roswell, New Mexico.
