<p> Rainfall estimation from satellite observations has uncertainties and inconsistency at different locations and so four different satellite products were selected for validation in Saudi Arabia. The satellite products selected for this study are TRMM, PERSIANN, CMORPH, and GSMap-MVK which are compared with gauge observed rainfall data using conventional statistical methods at daily, 10-daily, and monthly time scale. The validation results show that all the products can predict rainfall in the study area reasonably well but overestimates rainfall in the regions. However, this bias is comparatively less in the semi-arid part of the country where most of the rain falls. Therefore, all the four satellite products were used in SWAT model to study the hydrologic response in a semi-arid watershed located in the western part of the country. Results show that simulation from TRMM rainfall estimates agrees better with that of gauge observations at daily time scale.</p>
