The Fengyun-3E ( FY-3E ) satellite was successfully launched into an early morning orbit on 5 July 2021, carrying a Microwave Humidity Sounder-2 (MWHS-2) to provide vertical profiles of atmospheric temperature and humidity. In this study, the all-sky FY-3E MWHS-2 radiances are effectively assimilate...
