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.
Christy et al. (2007) claimed that tropical temperature trends from radiosondes matches closest with his v5.2 UAH dataset. [36] Furthermore, they asserted there was a discrepancy between RSS and sonde trends beginning in 1992, when the NOAA-12 satellite was launched.
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.
Satellite datasets show that over the past four decades the troposphere has warmed and the stratosphere has cooled. Both of these trends are consistent with the influence of increasing atmospheric concentrations of greenhouse gases .
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]
A 2014 study introduced a more sophisticated method of Kriging from the UAH satellite dataset, and found that this considerably reduced the hiatus. [ 59 ] Global (land and ocean) surface temperature anomaly time series with new analysis (solid black) versus no corrections for time-dependent biases (blue).

In 2016, UAH added men's and women's lacrosse to its varsity athletic programs. [21] UAH is a member of the National Collegiate Athletics Association (NCAA), competing in Division II in 15 sports. UAH is a member of the Gulf South Conference in all sports except men's lacrosse, which plays in the men's lacrosse (Peach Belt Conference).
