Percentage of deforestation and total annual rainfall for the Amazon arc of deforestation (1980 to 2012)

Annual Precipitation data for Amazon arc of deforestation: We aggregated the monthly precipitation dataset comes from Brazil Gridded Meteorological Data from 1980-2013 Project (Xavier et al., 2015, doi:10.1002/joc.4518) to annual time scale. These data are a gridded time series of monthly millimeters of rainfall from 3625 rain gauge and 735 weather stations across Amazon arc of deforestation at high‐resolution grids of 0.25∘ × 0.25∘ spatial resolution (approximately 28 km at the equator).Percentage of deforestation for the Amazon arc of deforestation: We used the longest agricultural land use database currently available for the region, the Brazilian Historical Agricultural Land Use database (BHALU; Dias et al., 2016) (available at http:// www.biosfera.dea.ufv.br/en-US/banco/uso-do-soloagricolano-brasil-1940-2012---dias-et-al-2016). These maps were originally constructed at 30 m spatial resolution (~1 km × 1 km). The final data are in hectares of each land use category per pixel, which for our database were converted into percentages of deforested land per pixel.Files "Prec_sum_YYYY.tif": Total annual rainfallFiles "LU_YYYY.tif": Annual percentage of deforestationwhere YYYY is the year from 1980 to 2012.
