Forest exposure (vulnerability) index, 2061-2080, based on MRI-CGCM3, rcp45: .
Summary
Exposure (vulnerability) index for the future time period (2061-2080) representing projected climate conditions from the MRI-CGCM3 GCM and the rcp45 emissions scenario. The exposure model uses LANDFIRE vegetation data and Worldclim climate data .The raster values represent exposure scores for the corresponding vegetation type. The modeled vegetation types can be spatially associated with the exposure values by overlaying them with the "landfire_veg_sw_300m.tif" raster.Exposure values represent where the location falls in climate space relative to its recent historical distribution:5 (core 5% of historical climate space); 10 (5 - 10%; still very good); ... ; 95 (90 - 95%; within the historical distribution, but getting pretty marginal); [...]

Purpose
The Forest Vulnerability Index measures the projected exposure to climate stress, and can be used as an estimate of the likelihood of forest cover change given a perturbation. Four projected climate scenarios were evaluated for this project: 1) GCM : MRI-CGCM3, RCP45; 2) GCM : MRI-CGCM3, RCP85; 3)GCM : MIROC-ESM-CHEM, RCP45; 4)GCM : MIROC-ESM-CHEM, RCP85. For each scenario, two future time periods were modeled (2041-2060 and 2061-2080). The primary output product is a set of vegetation exposure rasters (see "exposure" folder), which contain the exposure scores for every 300 x 300 meter cell on the landscape. These can be spatially associated with the modeled vegetation types using the vegetation raster ("landfire_veg_sw_300m.tif" in the "veg" folder). See the XML metadata files associated with each raster file for additional information specific to the dataset.
