Atmospheric Water Vapor Profiler (SSM/T-2)

NSSDCA ID: 2003-048A-07

Mission Name: DMSP 5D-3/F16

Description

The SSM/T-2 Atmospheric Water Vapor Profiler is a cross-track scanning, 5-channel, total power microwave radiometer with three channels situated symmetrically about the 183.31 GHz water vapor resonance line and two window channels. There are 28 observations (beam positions) per scan for each of the five channels, with each observation having a spatial resolution of approximately 48 km. The total swath width is approximately 1500 km. 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.
