中文摘要：

为综合分析评估中国区域内临近空间卫星遥感探测的温度数据精度，利用2006年4月至2009年12月的COSMIC掩星探测数据与TIMED／SABER卫星探测数据进行对比分析，计算2种卫星数据之间的平均温度偏差和温度标准差，并统计分析随季节和纬度分布的温度偏差特征。对比统计结果表明，中国区域内2种卫星遥感探测数据的温度随高度变化的特征总体一致；其平均温度偏差均在2K以上，在15km附近偏差较大，在37～57km内平均温度偏差以约0．22K／km的速度随高度递增；同时，平均温度偏差在夏季最小，冬季最大，在35～60km内季节的变化对温度偏差影响较大，且温度偏差随纬度的变化在不同高度范围内呈现不同的分布特征。此次评估综合分析了COSMIC与TIMED／SABER在中国区域内的温度数据精度，能够为临近空间卫星探测数据在国内的应用提供一定的参考依据。

英文摘要：

The accuracy of temperature data from satellite sounding over China was analysed in this paper. The COSMIC radio occultation data and TIMED/SABER observation data during April 2006 to December 2009 were used to assess the accuracy of temperature. The mean temperature deviation and standard deviation were calculated, and analyze the distribution of temperature deviation with season and latitude analyzed. The result of comparison shows that temperatures from COMIC are consistent with those of SABER. The mean deviation is all over 2 K, and it is larger about 15 km and increases at about 0.22 K/km slope in 37-57 km. The deviation is minimum in summer and maximum in winter, and it presents larger difference of seasons in 35-60 km. The change of temperature deviation with latitude presents different distribution in different height scope. The assessment analyzes the accuracy of temperature from COSMIC and TIMED/SABER. It can offer certain basic reference for applied research of satellite sounding data in near space in China.
