Spatio-temporal variability of NDVI and land surface temperature in the Maule and Biobío Regions (2000-2012)

The Intergovernmental Panel on Climate Change (IPCC, Geneva, Switzerland) reports that climatic zoning requires new methodologies to discriminate homogeneous areas due to new scenarios generating global climatic change. The objective of this study was to perform climatic zoning by analyzing spatial...
