摘要:: 选取那曲等7个站点代表中国西南川藏地区的3个典型区域,将大气红外探测器(AIRS)卫星获取的温度、高度和水汽资料与西南涡加密观测试验所获得的L波段秒级探空资料的相应观测量进行比较,分析了AIRS资料与探空资料的一致性,并对7个站点的温度误差进行了统计分析。结果表明,AIRS卫星的高度和温度以及混合比资料与L波段探空数据有很好的吻合度,其中温度资料在高原地区的低层尚有较小偏差,在中高层一致性较高。AIRS卫星所测得的位势高度数据与探空资料相当一致。而AIRS获取的混合比资料在低层略小于探空资料,在高层基本吻合。因此,AIRS资料在川藏地区具有较好的适用性,能有效弥补探空资料在该区域(尤其是高原地...

Abstract:: This article selects seven sites such as Naqu，Ganzi，on behalf of the three typical area of Sichuan-Tibet region in China，Compared temperature，geopotential height and water vapor that in AIRS with that in L-band Sounding data which received from southwest vortex intensive observation test. Analyzed the consistency between AIRS data and sounding data，in addition，statistic and analyzes the temperature error of seven sites. The results show that the geopotential height data and temperature data in AIRS have very good goodness of fit of L-band sounding data. Among them，the temperature data in Tibetan plateau area have smaller deviation in lower levels，while higher consistency in upper atmosphere. In Sichuan basin，detection outcome is well at entire layer. And AIRS satellite measured geopotential height data and sounding data are consistent. This shows that the AIRS satellite’s temperature，geopotential height data has good applicability in Tibet plateau，Western Sichuan plateau and the Sichuan basin. But the AIRS mixing ratio is smaller than sounding data in lower levels of southwest region，while high atmosphere has highly precision with sounding data. Thus，AIRS data have good applicability in Sichuan-Tibet region of China; it can effectively make up for the situation that sounding data’s covering region is insufficient，particularly in plateau region.
