中文摘要: 气象卫星垂直探测资料在国外已广泛用于数值天气预报中,本文介绍了由气象卫星垂直探测资料反演大气温度廓线的方法及回归反演系数的计算。最后给出了利用NOAA-7 TOVS资料反演大气温度廓线的试验结果。试验结果与常规探测温度的比较表明:绝对平均偏差和均方根误差在各等压面上大致为2—3℃。

Abstract:The meteorological satellite sounding data has been used in numerical forecast in many countries. This paper introduces the methods for retrieving atmospheric temperature profiles from meteorological satellite vertical sounding data and the calculations of regression retrieval coefficients used in the statistical method. The preliminary results retrieved from NOAA-7 TOVS data using the statistical method are shown in the end of paper. Comparisons between retrieval results and radiosounde data indicate: absolute mean bias and root mean square (RMS) errors about 2-3℃ at each pressure levels.
