These data are comprised of 60 individual GeoTIFF files that indicate whether fire is estimated to haved occurred in a given pixel for a given year. Each map is representative of one calendar year. These data are gridded versions of the vector geographic data provided by the Alaska Interagency Coordination Center (AICC; https://fire.ak.blm.gov/ ). Converting the polygon (i.e., vector) datasets to raster was done using ESRI software in ArcMap 10.1. Specifically, we used the function "Feature to Raster" under the Conversion Toolbox. A given pixel was classified as "fire occurrence" if the center of the pixel overlapped with a fire polygon from the AICC dataset. File Naming 'fire' - fire occurrence data 1 = fire occurrence -999 = No Data/No Fire '_xxxx' - year (1950-2009) '.tif' - file extention
