Estimation of Atmospheric Liquid-Water Amount by Nimbus 7 SMMR Data

[摘要] A new method of estimating vertically-integrated liquid-water amount and identifying precipitating clouds by Nimbus 7 SMMR data was presented on the basis of calculations of microwave radiative transfer. Comparison with other methods showed that the new method gives reasonable estimates for both precipitating and non-precipitating clouds. The method was applied to clouds in the western North-Pacific region in February of 1980, and some characteristics of integrated liquidwater amount, the relationship between averaged integrated liquid-water amount and cloud amount in each latitudinal zone, etc. were studied.
