Hi,I have some questions about satellite observations in reanalyses. Among those observations, that is related to precipitation only SSM/I ? Is there other satellite dataset adopted for making precipitation more accurate?Thanks!

In one sense, all the data assimilated is intended to make precipitation better. Consider that precipitation from reanalysis is derived from the background model forecasts, not the analysis of state fields to initialize the forecast. Any observation that improves the forecast, should improve the precipitation. That said, precipitation can be influenced by the water vapor assimilation.
