BrazilClim: script to gauge-calibrate the surfaces

A script that produces the monthly surfaces for each one of the covariates required to create the bioclimatic dataset: maximum and minimum temperatures, as well as precipitation. These surfaces are created applying several interpolation techniques, based on climatic information measured on-field (Supplementary Material A; DOI: 10.4121/14932947) and surfaces from GMTED2010 (digital elevation model), TRMM 3B43 v7 and NOAA (that must be downloaded from the respective sources). It also uses elevation and latitudes in the case of temperatures. Outputs are generated in GeoTiff format and 30 arc-sec resolution.
