摘要:

建立新的物理反演法能同时反演大气温度廓线、水汽廓线、表层温度和地表发射率,该反演算法应用到我国黄海地区AIRS红外卫星资料中,可反演得到较高垂直分辨率的大气温度廓线和水汽廓+线,同时反演得到的表层温度和地表发射率、根据水汽廓线计算大气可降水量。

关键词: 大气温度廓线, 水汽廓线, AIRS红外卫星, 表层温度, 大气可降水量

Abstract:

A new retrieval algorithm which can simultaneously retrieve atmospheric temperature profile, water vapor profile, surface skin temperature and surface emissivity is presented. The ralgorithm uses infrared radiances measured by Atmospheric Infrared Sounder (AIRS) in Yellow Sea region. The algorithm is applied to real AIRS observations and the results show that it is capable of retrieving high vertical resolution atmospheric temperature and water vapor. Surface skin temperature and surface emissity are simultaneously retrieved. The total precipitable water vapor (TPW) is computed by water vapor profile.

Key words: atmospheric temperature profile, water vapor profile, atmospheric infrared sounder satellite, surface skin temperature, total precipitable water vapor
