Abstract：Based on the reference of domestic MWP967KV microwave radiometer,the brightness temperature was calculated through the method of monochromatic radiative transfer model MonoRTM.The atmosphere temperature and the water vapor density were retrieving by multiple linear regression and the BP neural network method.By comparing and analyzing sounding data,there is little difference between the two methods of the accuracy.And the accurate stability of BP neural network inversion is better than multiple linear regression method to some extent.
