Abstract

An iterative solution is developed for the temperature and absorbing gas profiles of an atmosphere from spectral and angular measurements of atmospheric radiance. This iterative solution is novel in that there is no limiting assumption made about the analytical form of the profile imposed by the number of radiance observations available. The solution is demonstrated through the determination of temperature and water vapor profiles of the earth's atmosphere from Nimbus III and Nimbus IV Satellite InfraRed Spectrometer (SIRS) observations. The solutions are compared with conventional rawinsonde and rocket-sonde observations. The results indicate that this solution can be used effectively to specify the general meteorological characteristics of an atmosphere from satellite or ground-based radiometric observations.

摘要

通过对大气辐射的光谱和角度测量，开发了一种用于求解大气温度和吸收气体廓线的迭代方法。这种迭代方法的新颖之处在于，对于由可用辐射观测数量所限定的廓线分析形式，没有做出任何限制假设。通过利用雨云三号和雨云四号卫星红外光谱仪（SIRS）的观测数据来确定地球大气的温度和水汽廓线，对该方法进行了验证。将所得结果与传统的探空气球和火箭探空观测结果进行了比较。结果表明，该方法可有效地用于根据卫星或地面辐射测量观测来确定大气的一般气象特征。
