摘要
利用最小方差算法对NOAA/AMSU(Advanced Microwave Sounding Unit)探测资料在105°E^135°E、0~30°N海域范围内的大气温度垂直廓线进行了反演研究。利用NCEP再分析资料对算法的反演性能进行了验证;并与中国海洋大学卫星地面站SeaSpace/TeraS-can软件系统反演的温度廓线进行了比较。结果表明:该算法在中国区域具有较好的反演精度和适应能力;总体上改善了TeraScan软件的反演结果,尤其提高了对流层大部分区域的反演精度。本研究为地面站ATOVS(Advanced TIROS Operational Vertical Sounder)数据的进一步利用提供了一种较好的理论参考。
The vertical temperature profiles at the region of 105°E-135°E and 0-30°N are retrieved with the minimum variance algorithm and the data of NOAA/AMSU. The retrieved temperature profiles are verified and discussed based on the nearest collocated NECP reanalysis data. Compared with the same results retrieved by SeaSpace/TeraScan at the satellite station in Ocean University of China, the minimum variance algorithm shows good precision and adaptability in the region of China and it is better than SeaSpace/TeraScan algorithm generally, especially in troposphere. This study can give a good reference for the further use of ATOVS data.
