PASSIVE MICROWAVE MEASUREMENTS OF SEA SURFACE TEMPERATURE

Abstract

RCA Astro-Electronics conducted a field experiment to verify a theoretical approach toward remote sensing of sea surface temperature using passive microwave radiation. There is a correspondence between the radiometric temperature of the sea and its thermometric temperature. This correspondence is influenced by the horizontal and vertical emissivity, the incidence angle at which the radiometric measurement is being made, contaminants on the water surface, and by the sea surface roughness. The experiment addressed itself to two basic questions: (1) Can one measure the vertically and/or horizontally polarized microwave radiometric emissions from the sea water and obtain an accurate measure of the thermometric temperature. (2) Can one also make a determination of sea state from such measurements. The radiometric measurements were made from North Island of the Chesapeake Bay Bridge and Tunnel District. The bulk of the microwave measurements were made at a frequency of 16.5 GHz.
