AB: The performance of the operational NOAA/NESDIS Hydro-Estimator (HE) satellite rainfall algorithm over northwestern Mexico was evaluated for the 2002, 2003, and 2004 monsoons using raingauge observations taken from the North American Monsoon Experiment (NAME) Event Raingauge Network (NERN). The NERN consists of 87 tipping-bucket raingauges that are situated to depict terrain-induced precipitation features, and they were installed as part of the NAME program to improve the understanding and predictability of warm-season precipitation in southwestern North America. The 4-km HE precipitation estimates are compared with these calibrated raingauge observations to assess whether satellite-based estimates are able to capture such terrain-induced rainfall characteristics that are convective in origin. The study presents comprehensive error statistics and confidence level information of the algorithm from the three seasons of study. The validation results are also used to explore some of the hydrologic impacts on streamflow and/or soil moisture at the event timescale over one basin in the NAME region.
