Validation of wind speeds and significant wave heights observed by the TOPEX altimeter around Japan

Short Contribution


The wind speeds and significant wave heights observed by the TOPEX altimeter during the first 30 repeat cycles (for about 10 months) are validated by comparing with the data obtained at Japanese Ocean Data Buoy stations. The values of Kuband σ0 observed by the altimeter show good agreement with those estimated from the buoy wind speed using the modified Chelton-Wentz algorithm. The wind speeds derived from the Ku-band σ0 using the algorithm agree well with the buoy data with an rms difference of 1.99 ms−1. The significant wave heights observed by the altimeter have a systematic bias of 0.3 m.
