Abstract

This study validated the Global Precipitation Measurement (GPM, IMERG version 06), with the rain gauge data at various physiographic regions of Pakistan for a period of 07 years (i.e. 2014-2020) at average annual scale using mean monthly data. The outcomes indicated that in average annual scale, IMERG-v06 product delineated a very strong correlation coefficient (0.94 & 0.92) in low to moderate elevated areas including Nawabshah (37m) and Panjgur (968m) in the south most region, whereas moderate correlations have been observed (0.67 & 0.71) with the same low to moderate elevated region i.e. in Bannu (406m) and Balakot (995m) in north of the country. Maximum root mean square deviation (RMSD) of 2.33 mm/day was observed Balakot and minimum RMSD of 0.14 mm/day was recorded at Panjgur. This study reveals that the GPM (IMERG-V06) is a reliable source of precipitation measurement with minor and acceptable errors at different elevation regions of Pakistan.
