Abstract

The design principle and structural features of a new type dual-channel ground-based microwave radiometerfor measurement of water vapor and liquid water in troposphere are discussed. A method independent ofradiosonde data is used for system absolute calibrations. A statistical method for retrieving the total watervapor and cloud liquid water content and a nonlinear iterative algorithm for retrieving the water vapor profilesin the troposphere are discussed. Comparison is conducted between the measurement of the integrated amountsof the water vapor and the tropospheric vapor profiles by the radiometer and the radiosonde data.
