Calibration. The calibration of microwave radiometer sets the basis for accurate measured brightness temperatures and therefore, for accurate retrieved atmospheric parameters as temperature profiles, integrated water vapor and liquid water path.

The simplest version of a calibration is a so-called "hot-cold" calibration using two reference blackbodies at known, but different, "hot" and "cold. Observations from the satellite microwave sounders play a vital role in measuring the long-term temperature trends for climate change monitoring.

Changes in diurnal sampling over time and calibration drift have been the main sources of uncertainties in the satellite-measured temperature trends. We examine observations from the first of a series of U.S.
