中文摘要: 无论从气象角度还是气候角度讲,对卫星云辐射测值进行反演判释研究,从而提取诸如云顶高度、云顶温度、云的放射率、云厚以及云的含水量等参数都十分必要。本文主要介绍用NOAA卫星红外和微波通道测值,按其辐射率差比方法,定量判释两层云高的初步数值试验结果。经与地面实况对照分析表明:适当选择两组探测通道组合可以遥感两层云高,但还不能判释出中云和低云并存时各自的高度。

Abstract:It is necessary to study cloud parameter retrievals from cloud radiance measurements in order to obtain cloud-top height and temperature,cloud emissivity and thi-ckness, and perhaps cloud water content etc.This paper presents the preliminary results of the numerical test for retrieving two-level cloud height from a radiance ra- tioing method using NOAA satellite radiance measurements in the 15μm carbondioxide hand and 5,5μm oxygen band .(i.e. infrared and microwave channels). The comparison between the calculated and ground-thuth data shows that two-level cloud height can be obtained using a proper combination of two sets of channel measurements, but if middle and low level clouds Simultaneously occur these cloud heights can not be classified.
