In this study, we analyzed the suitability of using CHIRPS, CMORPH and TRMM platforms in monitoring extreme precipitation events, precipitation–runoff relationships, seasonal/year-to-year variability Saltito semiarid sub-basin Mexican state Durango. Satellite products (SPP) 16 sites were contrasted point to with data from rainfall gauge stations a daily temporal resolution for period four years (2015–2019). Using information, constructed Rx1d, Rx2d, R25mm, RR95 indices. For runoff model based on Storm Water Management Model (SWMM) was calibrated validated data, obtained Qx1d, Qx2d, Qx3d We used bias volume (%), MSE, correlation coefficient, median evaluate ability satellite detect analyze run flow events. Although these sensors tend overestimate both levels occurrence their high spatial resolutions make them reliable tool analysis trends climate change As result, they serve as useful resource evaluating intensity region, particularly terms patterns. They also allow hydrological modeling observation relationships. This is relevant absence hydrometric which usually common vast regions developing world.
