Fire Severity Classification
Fire severity classification (low, moderate, high) that burned within the last 10 years (2012-2021). The difference-adjusted relativized difference normalized burn ratio (RDNBR)... -
Total Fuel (Dead and Down) Load
Stephens et al. (2022) note that total dead/down values over 20 (short) tons/ac (40 Mg/ha) resulted in high severity in 56% of the pixels. Higuera and Abatzoglou (2020) note... -
Structure Exposure Score
Structure Exposure Score is an integrated rating of wildfire hazard that includes the likelihood of a wildfire reaching a given location along with the potential intensity and... -
Standing Dead and Ladder Fuels
This is the material that may burn at the extreme end of the spectrum and contribute to mass fire behavior (Stephens et al., 2022), especially during crown spread type events.... -
Sierra Nevada - Large Tree Density - > 30" Dbh
Large trees are important to forest managers for multiple reasons: they have a greater likelihood of survival from fire; they are an important source of seed stock; they provide... -
Sierra Nevada - Large Tree Density - 24" - 30" Dbh
Large trees are important to forest managers for multiple reasons: they have a greater likelihood of survival from fire; they are an important source of seed stock; they provide... -

This metric expresses the total amount of existing biomass volume (measured in dry weight tons per acre) from all live tree crowns (branchwood and foliage) and the tree stems... -
Potential Total Smoke Production Index
This metric is an index of the potential smoke production (represented by particulate matter that is 2.5 microns or less in diameter, or PM2.5) that could be emitted for a given... -
Potential Avoided Smoke Production Index
This is an index of how much less smoke (as defined by PM2.5 emissions) would be produced from a given pixel by burning under moderate fire weather conditions rather than the... -
