Abstract

Total Precipitable Water (TPW) calculations using the Special Sensor Microwave Water Vapor Sounder (SSM/T-2) launched November 1991 on the Defense Meteorological Satellite Program (DMSP) F-11 satellite are compared with TPW values obtained from analysis of the collocated Special Sensor Microwave Imager (SSM/I). The four data sets used were collected over the ocean. The different characteristics of these instruments are described. Their response to the ambient conditions indicate that the two independent measures of TPW generally agree within 20 percent over the range of TPW observed. Some direct measurements of TPW obtained from radiosondes at the time and in proximity to the satellite overpasses are presented for independent comparison.
