AB: Long and continuous meteorological data series for large areas are hard to obtain, so several groups have developed climate datasets generated through the combination of models and observed and remote sensing data, including reanalysis products. This study compares eight different precipitation datasets for South America (NCEP/NCAR-2, ERA-40, CMAP, GPCP, CRU, CPTEC, TRMM, Legates and Willmott, Leemans and Cramer). For each dataset, we analyze the four moments of the data distribution (mean, variance, skewness, kurtosis), for latitudinal variation, for the major river basins and for the major vegetation types in the continent, allowing to identify the geographical variations in each dataset. We verified that significant differences exist among the precipitation products.
