Welty, J.L., Jeffries, M.I., 2020, Combined wildfire datasets for the United States and certain territories, 1878-2019: U.S.Statistics from the CNFDB compared with the NFD Researchers plan to update the dataset yearly as new wildfire information becomes available. In addition to the polygon data, the dataset also contains summary rasters displaying a count of the number of times each pixel burned, the first year burned, and the most recent year burned. All wildfires have the attributes of original data source or sources that contain the polygon, additional names, codes, and dates that may be associated with the wildfire polygon. Whenever possible, the following attributes were associated with these fires: fire name, fire code, ignition date, controlled date, containment date, and fire cause. since 1878 but only those from the contributing data sources with a documented fire year.
