On The analysis of seasat winds

Abstract

A method for analyzing SEASAT-A-winds, which eliminates the ambiguity in SEASAT wind measurements, is formulated. The ambiguity is eliminated by using wind estimates from low level cloud motions and synoptic cloud patterns (based on satellite pictures), surface wind climatology as well as space-time continuity. The method was applied to SEASAT data taken over the tropical Atlantic. The accuracy of the method has been evaluated by comparing the result of our analysis technique with independent observations from ships. The comparison shows that the analysis technique produced winds which are comparable in accuracy with ship winds.
