This study evaluates the performance of seven gridded precipitation datasets (CRU TS, TMPA 3B43, GPCC, IMERG, MERRA-2, ERA5, and PDIR) against rain gauge data. The accuracy of these datasets in representing precipitation patterns is assessed from 2000 to 2017, with a focus on their performance across diverse climate zones in Iran.
