WorldClim high resolution global climate surfaces

Hijmans, R.J., S.E. Cameron, J.L. Parra, P.G. Jones and A. Jarvis, 2004. The WorldClim interpolated global terrestrial climate surfaces. Version 1.3. Available at http://biogeo.berkeley.edu/ WORLDCLIM is a set of global climate layers (grids) on a grid with a very high spatial resolution of. The data layers were generated through interpolation of average monthly climate data from weather stations on a 30 arc-second resolution grid (often referred to as "1 km2" resolution). ANUSPLIN software was used for interpolation. Latitude, longitude and elevation (SRTM30) were used as independent variables. Climate elements included are monthly total precipitation, and monthly mean, minimum and maximum temperature, and 19 derived bioclimatic variables.
