Wind Direction Effect on Sea Surface Emissivity.

Abstract

The effect of surface wind direction on sea surface emissivity was studied for wavelengths of 3.7, 8.8, 11, and 12μm. Wind direction is considered for 0°, 45°, 90°, 135°, and 180° from the direction of emitted radiation, while wind speed is changed from 1 to 15m/s. Computation showed that wind direction has little effect on sea surface emissivity ( 60° where the wavelength dependence of the emissivity difference caused by wind direction change is low (<0.003).
