Abstract
Rainfall is the main driving variable to impact the hydrologic model results. In the context of unavailability of actual rainfall data, researchers use global data, derived from the satellite for hydrologic assessment of a watershed. In this study, Climate Forecast System Reanalysis (CFSR) precipitation data are tested for its reliability in regard to Assam, India; which is characterized by a wide spatial variation of rainfall. Based on the observed wet days’ records, the CFSR precipitation datasets are compared with two sets of actual gauge rainfall data, viz. Indian Meteorological Department (IMD) data and Tea Garden data. From the results of this study, the CFSR data are found to be 34.94% deficient in annual rainfall volume than the actual gauge measurements.
