Abstract

A technique to measure both sea surface temperature and sea-air temperature difference from an airborne platform is described. The technique uses a scanning microwave radiometer operating in the 5-mm oxygen absorption band. To independently measure the sea surface temperature, a nadir-viewing infrared radiometer operating near 10 micrometers was also operated. Retrievals of the water-air temperature difference from the 5-mm wavelength radiometer data are presented and compared with buoy measurements. An additional comparison of water temperature measurements by microwave radiometer, infrared radiometer, and buoys is presented.
