中文摘要：

红外线的大气的发出声音干涉仪(IASI ) 是大气的发出声音仪器在 MetOp 上装了的新产生的 ultraspectral -- 一，第一颗运作的极转的卫星为气象学的卫星(EUMETSAT ) 的利用由欧洲组织发展了。它是一超离频能检测大气的化学作文，温度，和湿度的光谱决定的大气的察觉者与高精确性和分辨率介绍。在现在的学习，通过比较级， IASI 和雷送观察(无线电探空仪观测)的类似和差别的分析浇蒸汽数据，并且在 IASI 和水空气之间浇蒸汽检索，一详细说明，对在高原区域上的 IASI 水蒸汽检索的可靠的系统的评价被做。有在西藏的高原上的表情检索和 RAOB 大小的 IASI 检索的比较表明 IASI 检索数据是可靠的并且能被用于进行进一步的研究。

英文摘要：

The Infrared Atmospheric Sounding Inter- ferometer （IASI） is a new-generation ultraspectral at- mospheric sounding instrument mounted on the MetOp-A, the first operational polar-orbiting satellite developed by the European Organisation for the Exploitation of Mete- orological Satellites （EUMETSAT）. It is an ultrahigh spectral-resolution atmospheric detector which can detect atmospheric chemical composition, temperature, and hu- midity profiles with high accuracy and resolution. In the present study, through comparative analyses of the simi- larities and differences between the IASI and the ra- diosonde observation （RAOB） water vapor data, and be- tween the IASI and the Aqua-AIRS water vapor retrievals, a detailed and systematic assessment of the credibility of the IASI water vapor retrievals over the plateau region was made. A comparison of the IASI retrievals with the AIRS retrievals and the RAOB measurements over the Tibetan Plateau revealed that the IASI retrieval data are reliable and can be used for conducting further studies.
