                         spatial resolution of 0.25 degrees is performed over the 
                         subtropical Andes, an area of highly complex topography: The

                         Prediction Center Morphing technique (CMORPH) and the 
                         Hydro-Estimator (HYDRO). Remote mountainous regions represent a 
                         major challenge for these satellite data products and for studies 
                         examining their quality with surface data. For the assessment of 
                         the satellite products, a period of seven years from January 1st 
                         2004 to December 31st 2010 was considered. Different statistics 
                         were analyzed considering their variability in the study area and 
                         identifying their main differences between the warm and cold 
                         seasons. The results indicate a decrease in winter errors which 
                         coincides with the wet season over the windward side of the Andes. 
                         Also, a significant underestimation of precipitation is observed 
                         for all estimates throughout the period analyzed. The analysis 
                         with respect to terrain height shows a greater dependence of 
                         errors with topography for all the algorithms that combine 
                         infrared and passive microwave data, HYDRO providing the most 
                         stable result. The main limitations of the estimates associated 
                         with the type of precipitating event and their location relative 
                         to the orography are assessed. Finally, the analysis of two 
                         intense precipitation events is presented and allows the 
                         assessment of the latest advances in satellite derived estimates 
                         with the launch of the Global Precipitation Measurement.",
