| 摘 要： | 利用AURA/MLS数据（V4.2）和TIMED/SABER数据（V2.0）对20~92km高度的大气温度进行比较分析，计算AURA/MLS数据与TIMED/SABER数据的温度绝对偏差，并分析平均温度偏差在不同季节中随经度、纬度和高度的变化特征.结果表明:20~80km高度的平均温度偏差在±6K以内，相对偏差在3%以内；80~90km高度平均温度偏差减小至-10K以下，相对偏差在9%以内.中低纬度地区平均温度偏差廓线的变化趋势一致，从20km高度的-3K左右的负偏差逐渐增加，在45~50km高度的平流层顶处有较明显的3K左右的正偏差峰值.平均温度偏差随纬度变化明显，随经度变化很小.研究结果可为卫星数据的应用提供参考依据.

| Abstract: | Atmospheric temperature data from 20 to 90km height measured by AURA/MLS is compared with those measured by TIMED/SABER. The absolute temperature deviation between AURA/MLS data and TIMED/SABER data is calculated, and the feature of the average temperature deviation with latitude, longitude and altitude is analyzed. The results show that the average temperature deviation from 20 to 80km is smaller than ±6K, and the relative deviation is smaller than 3%. The average temperature deviation from 80 to 92km decreases to -10K, and the corresponding relative deviation is smaller than 9%. The variation tendency of average temperature deviation at mid and low latitude has almost the same trend. The deviation at 20km is -3K, and it increases gradually to a positive peak of 3K at 45~50km. The average temperature deviation varies obviously with latitude, while varies very less with longitude. The results are of interest for satellite data application. |
