摘　　要：为综合分析评估2004年11月在中国酒泉卫星发射中心的首次临近空间气象火箭探测资料精度,分别利用经验预报模式资料和卫星遥感资料进行对比.分析结果表明,由于经验预报模式时空分辨率低,同时缺乏中国区域平流层的中上部以上高度的探测数据,在平流层中上部以上高度与气象火箭探测资料的偏差较大;相比于经验预报模式,气象火箭探测资料与卫星资料的偏差明显减小,偏差主要由两者的系统性误差和对比点在时间及经纬度的差异造成的.综合对比结果表明,相比于经验预报模式资料和卫星遥感资料,气象火箭探测资料的精度较高,具有较强的可信度,可对其他方式的探测结果进行标定.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.
