The cross matching of sea surface wind speed retrieved by China-France Oceanography SATellite (CFOSAT) SCATterometer (hereinafter referred to as “CSCAT”) and Advanced SCATterometer (ASCAT) onboard MetOp (Meteorological Operational)-A/B/C satellites (hereinafter referred to as “ASCAT-A/B/C”) in the same period of 2021-2022 is carried out according to the space-time windows of 30 min and 50 km, and then after rainfall and land quality control, the matched data is studied with respect to correlation, relative error and deviation analysis of wind speed distribution. The results are listed as follows. (1) After quality control, the correlation coefficient between CSCAT and ASCAT-A is 0.94-0.97, and the root mean square error is 0.82-1.89 m·s^-1. (2) The wind speed of CSCAT is 30%-70% larger than that of ASCAT-A/B/C when the wind speed is below 2 m·s^-1, 0-5% smaller than ASCAT-A in the range of 2-21 m·s^-1, 3%-30% larger than ASCAT-B/C in the range of 2-3 m·s^-1, and 2%-10% smaller than ASCAT-B/C in the range of 4-17 m·s^-1. (3) In 2021, the overall wind speed of CSCAT in China’s offshore areas is larger than that of ASCAT-A, and the wind speed of CSCAT is 0.5-1.5 m·s^-1 larger than that of ASCAT-A in the East China Sea, the South China Sea, the Philippines and the waters east of it in January. The wind speed of CSCAT is 1.0-1.5 m·s^-1 larger than that of ASCAT-A in the Yellow Sea and the South China Sea in July, which is consistent with the changes in the monthly mean wind speed in China’s offshore areas in 2021, showing that the cross validation of wind speed can well reveal the difference in wind speed between satellites.
