为了评估RPG-HATPR O微波辐射计的探测性能,文章对比分析了广东省清远市探空观测站的探空观测数据与微波辐射计数据,通过比较不同观测高度、不同天气条件下的数据质量分析仪器性能.结果表明:RPG-HATPRO微波辐射计边界层温度廓线的有效探测高度为2 000 m,对流层湿度廓线的有效探测高度为10 000 m;微波辐射计的对流层温度数据探测误差分布随高度增加呈曲折上升趋势;降水条件对微波辐射计温度、湿度数据准确性有一定影响,在无降水条件下,微波辐射计湿度数据的准确性更为稳定.研究结果为微波辐射计的更有效应用提供支持.
Comparative analysis of microwave radiometer and sounding observation data
In order to evaluate the detection performance of RPG-HATPRO microwave radiometer,this paper compares and analyzes the sounding observation data and microwave radiometer data of the sounding observation station in Qingyuan City,Guangdong Province.By comparing the data quality under different observation heights and different weather conditions the instrunment perfirmance was analyed.The results show that the effective detection height of the boundary layer temperature profile of RPG-HATPRO microwave radiometer is 2 000 m.The effective detection height of tropospheric humidity profile is 10 000 m.The detection error distribution of tropospheric temperature data of microwave radiometer shows a tortuous upward trend with increasing height.Precipitation conditions have a certain influence on the accuracy of temperature and humidity data of microwave radiometer.Under the condition of no precipitation,the accuracy of humidity data of microwave radiometer is more stable.The research results provide support for the more effective application of microwave radiometer.
