Contemporary methods for retrieving the integrated atmospheric water-vapor content and the total cloud liquid-water content

A review of contemporary methods for determining integrated parameters of the water content in the atmosphereaEuro center dot atmospheric water-vapor content and cloud liquid-water contentaEuro center dot is presented. Fields of these parameters can only be mapped spatially on the basis of using data of satellite measurements. The least errors of the retrieval of atmospheric water-vapor content and cloud liquid-water content is provided by methods based on using measurements of the satellite-borne scanning multichannel microwave radiometers over the ice-free ocean areas in the absence of precipitation. Most methods for retrieving the atmospheric water-vapor content and cloud liquid-water content from the data of microwave radiometers are based on results of numerical simulation of brightness temperatures of the upwelling microwave radiation of the ocean-atmosphere system. The evolution of satellite-borne microwave radiometers and methods for the retrieval of integrated parameters of water content is presented.
