We use the data obtained from empirical forecast model and satellite remote sensing to analyze and assess the accuracy of the data obtained from first near space meteorological rocket sounding in Jiuquan Satellite Launch Center (JSLC) in November 2004. Analysis shows that the data of empirical forecast model has great difference from meteorological rocket sounding data for the middle-upper stratosphere. Because the empirical forecast model has low spatial and temporal resolution, especially it lacks of the sounding data for the middle-upper stratosphere in China, the deviation between the data of meteorological rocket and the satellite data is obviouslly lower than the empirical forecast model gave. The deviation is caused by the systematic error between the two and the difference of time, latitude and longitude. Comprehensive comparison results show that the data of meteorological rocket is of high accuracy and credibility compared to the data of the empirical forecast model and satellite remote sensing. These data can be used to specify the probe’s results from other ways.
