In-Situ Measurements for Validation of Microwave Data: Problems, Accuracies

Abstract

ABSTRACT. This review covers the relationship between remotely sensed microwave data and data obtained in-situ or from earth based remote sensing systems both for validation of algorithms and as supplemental information for deriving a geophysical quantity. Parameters obtained from the satellite borne microwave radiometers, the Scanning Multichannel Microwave Radiometer (SMMR) and the Special Sensor Microwave Imager (SSMII) are emphasized. These include sea surface temperature and wind speed, integrated abllospheric water vapor, cloud liquid water and rain rate.
