AB: EPPrePMex is a tool for real-time rainfall estimation, calibrated for the Mexican territory and based on satellite imagery. We have implemented, calibrated and operationally evaluated the CST technique (by Adler and Negri) for Mexico. The results show that, in general, EPPrePMex gives an overestimation of the rainfall field. We have realized systematic comparisons for daily rainfall estimations over Mexico and USA with comparable results obtained with HydroEstimator(NOAA). However In order to improve our system, several modifications are planned: a) Calibration for different regions, season and kind of storms, b) A joint use and calibration of satellite and radar images, c) Dynamic study of storms, and d) Real time calibration with microwave and other kind of sensor data from low orbit satellites. We have proposed hydrological applications of the operational results of the EPPrePMex system (real time forecast and warning systems)for central and SW Mexico.
