Abstract

High wind speed data were obtained by using the angular momentum model and their precision was verified by the weather station recorded data. A wind speed inversion algorithm for altimeter was developed by using these wind speeds. The results show that this new algorithm can inverse the sea surface wind speed more accurately when typhoon passes through, which realizes the high wind speed (10~40 m/s) inversion for altimeter. This, therefore, can be taken as the supplement of altimeter wind inversion algorithm for Jason-1 at the high wind speed, and improve the precision of altimeter wind inversion algorithm.
