Data are provided as temperature anomalies against the seasonal average over a past basis period, as well as in absolute temperature values. The baseline period for the published temperature anomalies was changed in January 2021 from 1981-2010 to 1991-2020. [4] All the data products can be downloaded from the UAH server. [5]
Roy Warren Spencer (born December 20, 1955) [1] is an American meteorologist. [2] He is a principal research scientist at the University of Alabama in Huntsville , and the U.S. Science Team leader for the Advanced Microwave Scanning Radiometer (AMSR-E) on NASA's Aqua satellite .
One widely reported satellite temperature record is that developed by Roy Spencer and John Christy at the University of Alabama in Huntsville (UAH). The record comes from a succession of different satellites and problems with inter-calibration between the satellites are important, especially NOAA-9, which accounts for most of the difference ...
[5] [6] Since the data correction of August 1998 (and the major La Niña Pacific Ocean warming event of the same year), data collected by satellite instruments have shown an average global warming trend in the atmosphere. From November 1978 through March 2011, Earth's atmosphere has warmed at an average rate of about 0.14 C per decade ...

RSS is a widely cited source of data on the satellite temperature record.Their data is one source of evidence for global warming.Research by Carl Mears, Matthias Schabel, and Wentz, all of RSS, highlighted errors in the early satellite temperature records compiled by John Christy and Roy Spencer at UAH, [1] [2] which had previously showed no significant temperature trend, bringing the derived ...

[1] [2] The resulting temperature profiles depend on details of the methods that are used to obtain temperatures from radiances. As a result, different groups that have analyzed the satellite data have produced differing temperature datasets. The satellite time series is not homogeneous.
