Abstract: Abstract Due to the raindrops in rain are acquired by charges, the prediction of a rain, such as its intensity of rain and rain thickness, based on the measurement data by remote sensing should be reconsidered because of the charges over the raindrops. The relations between the predictions of a rain, such as the radii of raindrop and the thickness of rain, and the measured data, such as the backscattering cross section per volume for active remote sensing of rain, and the relations between the predictions of a rain and the measured brightness temperature for passive remote sensing are respectively rebuilt, in this paper, based on the Mie theory and vector radiative transfer equations. Radiation brightness temperature is gotten by the method of Gauss integral, and the backward scattering section is gotten with iteration method. The results show that charges over raindrops have effect on the remote sensing measurement values that are used to estimate the thickness of rain, radii of raindrops and intensity of rain etc.
