The UAH satellite temperature dataset, developed at the University of Alabama in Huntsville, infers the temperature of various atmospheric layers from satellite measurements of the oxygen radiance in the microwave band, using Microwave Sounding Unit temperature measurements.
Since the earliest release of results in the 1990s, a number of adjustments to the algorithm computing the UAH TLT dataset have been made. [44] [8] A table of the corrections can be found in the UAH satellite temperature dataset article.
As a result, different groups that have analyzed the satellite data have produced differing temperature datasets. The satellite time series is not homogeneous. It is constructed from a series of satellites with similar but not identical sensors. The sensors also deteriorate over time, and corrections are necessary for orbital drift and decay.
John Raymond Christy is a climate scientist at the University of Alabama in Huntsville (UAH) whose chief interests are satellite remote sensing of global climate and global climate change. He is best known, jointly with Roy Spencer, for the first successful development of a satellite temperature record. [1]
Each record is plotted as the monthly average and straight lines are fit through each data set from January 1982 to December 2009. The slope of these lines are 0.187°C/decade, 0.163°C/decade, and 0.239°C/decade for the surface, UAH, and RSS respectively. The 5.2 version of Christy et al.'s satellite temperature record contains a significant ...
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.
Doubts had been raised as early as 2000 about the UAH analysis by the work of Prabhakara et al., [1] which minimised errors due to satellite drift. They found a trend of 0.13 °C/decade, in reasonable agreement with surface trends.
