In order to improve the consistency of sea surface wind speed (SSWS) data from different satellite altimeters,the SSWS data from the HY-2A,T/P,GFO,Jason-1,Envisat,Jason-2,and CryoSat-2 satellite altimeter are collected,and compared with NDBC buoy data. Then,the calibration formulas are given,and the calibration results are investigated. The results show that both the mean values (MVs) and root mean squares (RMSs) of the differences between the SSWS data from the satellite altimeters and the buoys decrease after the calibrations,and the case of the HY-2A satellite altimeter is most remarkable. The MVs are within ±0.2 m/s,and the RMSs are below 1.6m/s except the HY-2A,GFO,and Jason-1 satellite altimeters. Therefore,the calibration formulas presented in this paper are useful for reducing the differences between the SSWS data from the satellite altimeters and the buoys (especially for HY-2A satellite altimeter).
