HY-2扫描辐射计风速数据产品与平台基观测数据的比较研究
Comparison of the seawind data obtained by the scanning microwave radiometer aboard on HY-2 satellite with those obtained with the platform
摘要
Abstract
We compared the wind data obtained by the Scanning Microwave Radiometer aboard on HY-2 Satellite with those obtained with the platform from February 2012 to Septemper 2012 in the Northern South China Sea. The temporal and spatial differences between the HY-2 and platform-measured data were limited to less than 5 min and 25 km. The spatial resolution of HY-2 data used in our study was 100, 70 and 35 km. The Root Mean Square (RMS) between HY-2 wind speed data with 100 km resolution and the platform-measured wind speed data was about 3.86 m/s. The RMS between HY-2 wind speed data with 70 km resolution and the platform-measured wind speed data was about 10.52 m/s. The RMS between HY-2 wind speed data with 35 km resolution and the platform-measured wind speed data was about 5.54 m/s. We also calculated the RMS between the HY-2 wind speed data and the platform-measured data under the conditions with rain or without rain. In conclusion, the HY-2 wind speed data with 100 km resolution is best under the condition without rain, and the HY-2 wind speed data with 35 km resolution is best under the condition with rain. We have provided a basis for using sea wind data of the Scanning Microwave Radiometer aboard on HY-2 Satellite in the Northern South China Sea.关键词
