遥感大气中汽态水和液态水含量的实验研究

根据微波在大气中的辐射传输理论，采用接收１．３５ｃｍ和８ｍｍ波段的大气噪音，推算大气中水汽和液态水含量，研制了双通道微波辐射计，进行遥感实验，文章中对微波辐射计测得的数据如何校正，展开了详细的讨论，这将在监测和利用空中水资源的科学实验中发挥作用。

Experimental Study on Remote Sensing of Atmospheric Water Vapour Content and Liouid Water Content

The atmosphere is known as a source of heat noise in microwave bands.By means of ground-based reception of atmospheric emission constituted mainly by oxygen, water vapour, cloud and rain , we could get the atmospheric temperature profile, humidity and the parameters of cloud and rain. By using atmospheric noise reception of 1.35cm water vapour absorption band and 8mm window band , we could obtain the atmospheric total water vapour content and liquid water content of Cloud.We have constructed a dual-channel microwave radiometer and conducted observation experiments in Hebei and Shanxi provinces. In this paper the calibra-tion of the radiometer output data is discussed in detail. It can be used in the exper-imental research of the cloud-radiation characters and making use of natural water resources in the sky.
