[1] We validate the temperature climatology recorded by the Microwave Sounding Unit with GPS occultation data collected by the GPS/MET experiment.

We simulate the lower stratospheric channel’s brightness temperature by convolving each GPS/MET temperature profile with a vertical weighting function and then map the irregularly gridded data using a Bayesian interpolation scheme. In northern polar night, the MSU Tls deviates from GPS occultation by as much as 10 K while occultation is consistent with the NCEP Reanalysis used for diagnostic purposes.
