云含水量 meaning in English

cloud water content

As for a space - based cloud radar , the change of the radar reflectivity n and the change of attenuation rate along with the cloud liquid water content have been compared between 37 ghz and 94ghz . the transmittance t of single level cloud for different heights and liquid water content has also been calculated at 2 frequencies . by defining a = n tr , which combines both effects of radar reflectivity and transmittance , we have examined the values of a at 37ghz and 94ghz for high , middle and low cloud liquid water contents
对空间测云雷达，讨论了37ghz和94ghz这两个频率的雷达反射率和衰减系数随云液水含量的变化；计算了不同高度的单层云在不同频率，不同含水量情况下的云层透过率_ ；定义a = _来综合考虑雷达反射率和透过率对空间测云雷达回波的影响，分析比较了云含水量高、中、低时37ghz和94ghz的a值大小。
