Performance of IMERG as a Function of Spatiotemporal Scale

Abstract: The Integrated Multi-satellitE Retrievals for GPM (IMERG), a global high resolution gridded precipitation data set, will enable a wide range of applications, ranging from studies on precipitation characteristics to applications in hydrology to evaluation of weather and climate models. These applications focus on different spatial and temporal scale and thus average the precipitation estimates to coarser resolutions. Such a modification of scale will impact the reliability of IMERG. In this st…
