Multiple factors influencing burn severity for daily forested burn areas of central Idaho and western Montana

This data publication includes forested daily burned area shapefiles from 42 forest fires from 2005 to 2007 and 2011 for central Idaho and western Montana. Original files were obtained from https://ftp.nifc.gov/. Fire data were selected based on availability of burn severity (dNBR) from MTBS.gov and five days of consecutive infrared (IR) perimeter mapping and then further processed to remove areas smaller than 0.09 hectares, buffered inward by 30 meters, and only map forested areas. Also included is a file containing multiple measurements such as daily weather and fire danger indices, topographic measurements, and vegetation characteristics for random sample points within the 42 forest fire areas, as well as a file containing basic information about these fires.
Burn severity as inferred from satellite-derived differenced Normalized Burn Ratio (dNBR) is useful for evaluating fire impacts on ecosystems, but the environmental controls on burn severity across large forest fires are both poorly understood and likely to be different than those influencing fire extent.
