中国近海ASCAT风场反演结果验证分析
Validation of ASCAT wind vectors in the China Sea
摘要
Abstract
Based on NCEP wind data and dropsonde observational data,the accuracy of ASCAT wind products in the China Sea is validated.The results indicates that the mean absolute differences between ASCAT and NCEP data were 2.06 m/s (wind speed) and 21.98°(wind direction) based on the 845 matching samples.Meanwhile,the root-mean-square differences were 2.87 m/s (wind speed) and 34.29°(wind direction).The wind speed retrieval accuracy from ASCAT is close to NCEP while the wind direction difference is relatively large.The mean absolute differences between ASCAT and dropsonde data were 1.55 rn/s (wind speed) and 3.43° (wind direction) on the basis of 7 matching samples.The root-mean-square differences between them were 1.73 rn/s (wind speed) and 4.15°(wind direction).Hence,the ASCAT wind products well retrieval the tropical cyclones wind field.关键词
