Burn Severity Portal, a clearing house of fire severity and extent information (ver. 6.0, January 2024)

The various post-fire data products available on the Burn Severity Portal are produced using satellite imagery. The timing of the satellite imagery used, relative to the fire event, typically depends on the vegetation type and structure where the fire occurred. Each mapping program produces a suite of data products based on user intended user needs. For more information about each of the programs, please refer to each area individually. Requests are made for burn severity assessments through an agreement with the U.S. Geological Survey (USGS) to be completed by analysts with the Monitoring Trends in Burn Severity (MTBS) Program. The MTBS Program assesses the frequency, extent, and magnitude (size and severity) of all large wildland fires (wildfires and prescribed fires) in the conterminous United States (CONUS), Alaska, Hawaii, and Puerto Rico for the period 1984 and beyond. All fires reported as greater than 1,000 acres in the western U.S. and greater than 500 acres in the eastern U.S. are mapped across all ownerships. MTBS produces a series of geospatial and tabular data for analysis at a range of spatial, temporal, and thematic scales and are intended to meet a variety of information needs that require consistent data about fire effects through space and time. This map layer is a thematic raster image of an individual NPS-requested burn severity fire, occurring during a calendar year. Fires omitted from this mapped inventory are those where suitable satellite imagery was not available or fires were not discernable from available imagery. Assessments requested by the NPS may not meet the aforementioned size criteria, but otherwise adhere to all procedural and quality standards held by the MTBS Program.
