Burned areas and ignition dates from Monitoring Trends in Burn Severity (MTBS), a program of the US Geological Survey and the USDA Forest Service. Fire reports from Short, Karen C. 2022, Spatial wildfire occurrence data for the United States, 1992-2020 [FPA_FOD_20221014], 6th Edition, Forest Service Research Data Archive, doi.org/10.2737/RDS-2013-0009.6.
