Abstract:

Calibration and validation of the Defense Meteorological Satellite Program DMSP Special Sensor Microwave Water Vapor Sounder SSMT-2 is investigated. The objective of the effort is to obtain simultaneous independent measurements of microwave radiance, water vapor mass, specific humidity and relative humidity to quantitatively measure the performance of the instrument calibration and to validate the ability of the SSMT-2 to measure the water vapor parameters, i.e. the environmental data records EDRs of Air Force Global Weather Central AFGWC. Analysis of Satellite and aircraft data for calibration using both underflights and radiative transfer calculation show that the SSMT-2 is performing within or exceeds the original contract specifications 1K. The SSMT-2 retrieved vertical moisture profiles EDRs are performing within the contract specification of or - 30 RH when compared with collocated radiosonde data except over certain ocean atmospheres
