The multi-source merged global precipitation product (MGP; 0.25°/ hourly; 2000-2020; 60°N/S), which takes advantage of the complementary strengths of satellite, reanalysis, and gauge data to obtain reliable precipitation estimates over the global land surface, provides a new higher-quality precipitation dataset for data users to realize their respective research purposes and the social and economic activities. The data developers hope that MGP will play an important role in a variety of science communities (e.g., hydrology, meteorology, climatology, ecology, and agriculture).
