 The study found that the PGFv3 product had the highest accuracy when it came to representing precipitation in Chile. This product has a bias correction mechanism that uses 217 stations from Chile to correct for errors in the model. It also performs well across different elevations and seasons. The other products tested, including CHRPSV2, TMPA3B42V7, CMRPH, Persian CDR, Persian CCSADJ, and MSWEPV1.1, have varying levels of accuracy depending on the region and season. The study concluded that a site-specific assessment should still be done before any use in catchment-scale hydrological studies. This article was authored by M. Zambrano-Bigiorrini, Anaudet, C.
