Abstract | |||||||||
| Calibration and validation of the Defense Meteorological Satellite Program (DMSP) Special Sensor Microwave Water Vapor Sounder (SSM/T-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 SSM/T-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 SSM/T-2 is performing within or exceeds the original contract specifications (1K). The SSM/T-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 | |||||||||
