The Global Hydrology Research Group at the University of New Hampshire provides this excellent resource on regional hydrometeorological data for South America, Central America, and the Caribbean. Available in English, Spanish, or Portuguese, the data are organized by geographic location. Two large data sets are available to the general public: Monthly Time Series and Climatological (site-specific resolution) Hydrometeorological Data Sets, and Monthly Temperature and Precipitation Data Sets (30-minute spatial scale resolution). Data may be downloaded by country/ region (.zip, .tar, ascii, or .ps formats). Given the general paucity of publicly available, baseline information for this important region, R-HydroNET is a solid template upon which future data may be added.
