Precipitation is an essential climate and forcing variable for modeling the global water cycle.
Particularly, the recent Integrated Multi-satellite Retrievals for GPM (IMERG) product
retrospectively provides an unprecedented two decades of high-resolution satellite
precipitation estimates. The primary goal of this study is to examine the similarities and
differences between the two latest and also arguably the most popular, GPM IMERG Early
and Final Run (ER and FR) products across the globe. The results reveal that:(1) ER …

Precipitation is an essential climate and forcing variable for modeling the global water cycle.
Particularly, the Integrated Multi-satellitE Retrievals for GPM (IMERG) product retrospectively
provides unprecedented two-decades of high-resolution satellite precipitation estimates (0.1-
deg, 30-min) globally. The primary goal of this study is to examine the similarities and
differences between the two latest and also arguably most popular GPM IMERG Early and
Final Run (ER and FR) products systematically over the globe. The results reveal that:(1) ER …
