WorldClim is a set of global climate layers (gridded climate data in GeoTiff format) that can be used for mapping and spatial modeling. WordlClim version 2 contains average monthly climatic gridded data for the period 1970-2000 with different spatial resolutions. The older version of WorldClim (version 1.4) contains gridded data for the same variables for the period 1960-1990, as well as temperature and precipitation projections by the IPCC Fifth Assessment Report.
