摘　　要：具有空间高分辨率的卫星垂直探测（ＴＯＶＳ）资料应用于业务时，应对反演资料的偏差分布进行检验、统计、分析，以利于选取误差稳定且较小的区域（或指标点）作为寻求和归纳预报条件时可应用于业务的反演资料；同时，进一步研究和设计了误差订正方案，经比较分析，单点指标站经回归订正后误差能得到满意的改善。he examination , statistics and analysis for error distribution of TOVS data was conducted before appling TOVS data to operation. The areas which have little error were sellected to be the TOVS data areas of seeking and including forecasting factor. Then, an error correcting method was studied and designed. The results show that the error was decreased at single station through regression correcting and the quality of grid field was increased through calculus of variations analysis.
