Interactive comment on “Performance of GPM-IMERG precipitation products under diverse topographical features and multiple-intensity rainfall in an arid region”

Abstract

This work focused on the impact of several crucial factors including elevation, season, hydrological region and precipitation intensity on the precipitation retrievals of IMERG suite (i.e., Early, Late and Final runs) over Saudi Arabia. This is a very lengthy study, covering several important factors that influence the performance of satellite precipitation retrievals. However, I noted some issues that need clarification. a. The pertinent studies investigating the impact of these four crucial factors on the C1
