Abstract
A brief description of the MTVZA-GYa microwave radiometer installed on the Meteor-M No. 2 Russian polar orbiting meteorological satellite is presented. The procedures of bias correction and quality control indispensable in satellite data assimilation are considered. The operational system of global data assimilation by the Hydrometcenter of Russia is briefly described. Results of numerical experiments on the assimilation of MTVZA-GYa observations in six temperature-sensitive channels are given. It is demonstrated that the assimilation of these data significantly improves the accuracy of short-range weather forecasts in the Southern Hemisphere. The effect of the use of MTVZA-GY data in the Northern Hemisphere is neutral.
