|DMSP SSMT/2 - Atmospheric Water Vapor Profiler
|The SSM/T-2 sensor is a five channel, total power microwave radiometer with three
channels situated symmetrically about the 183.31 GHz water vapor resonance line and
two window channels. This instrument was flown on all DMSP Block 5D-2 satellites starting
with F11 launched in 1991. SSM/T-2 is designed to provide global monitoring of the
concentration of water vapor in the atmosphere under all sky conditions by taking
advantage of the reduced sensitivity of the microwave region to cloud attenuation.
