Texas Wildfires – March 2022

High winds, low humidity, and drought-parched grasses caused wildfires across the Southern Plains of the United States in mid-March 2022, including Texas. The United States Department of Agriculture's National Agricultural Statistics Service (NASS) responded to inquiries regarding the extent of agriculture affected by the Texas wildfires in near real-time. Wildfire perimeter location data was provided by the National Interagency Fire Center. False color composite images were generated from Sentinel-2 to represent pre- and post-fire images. The pre-fire image is a median image derived from January 1 through February 28 images and the post-fire image was derived from imagery dated March 20. Fire masks were derived from the MODIS Terra Thermal Anomalies & Fire Daily Global 1km Product dated March 17-21, 2022 to verify wildfire boundaries. Land cover information was derived from the NASS 2021 Cropland Data Layer.
