NASA has released its newest and most comprehensive estimate of rain and snow covering nearly 20 years. Version 6 of NASA's IMERG -- short for the Integrated Multi-satellitE Retrievals for Global Precipitation Measurement (GPM) -- combines information from a constellation of satellties that are operating in Earth's orbit, at a given time, to estimate precipitation over the majority of the Earth's surface.
