[BurnScars-dNBR]

This product is a daily visual display of large (5,000 acre) wildfire burn scars called “BRISK” (Burned area Rapid Interim Severity Risk) maps. It is created as a data fusion product with Google Earth Engine using input from these nine satellites GOES East, GOES West, SNPP, NOAA-20, NOAA-21, Landsat 8/9, Sentinel 2a/b.

Differenced Normalized Burn Ratio (dNBR) – A differenced NBR image, or change image, created where the post-fire NBR is subtracted from the pre-fire NBR. The dNBR may be used to discriminate burned from unburned areas and identify vegetation burn severity classes. The dNBR is calculated as: dNBR = NBR pre-fire – NBR post-fire For select fires, the preliminary dNBR is used by BAER to make a BARC (Burned Area Reflectance Classification) image in 256 categories and 4 categories that is in turn used by BAER teams to make a Soil Burn Severity (SBS) map. The preliminary dNBR is a relative measure or "indexed" product that theoretically runs from 0-100% but often contains measures outside of that range. The BARC classification classification thresholds are not published. We (SSEC/CIMSS) are applying an automated and generalized classification method for comparison to BRISK maps (which are automated). There is a trade-off between timeliness/automation and accuracy/manual interpretation.

This boundary shapefile is distributed with the published preliminary dNBR data by USGS/USFS and is available at the link below. It is useful for identifying the fire names associated with the burn scars. On a desktop browser, hovering over a perimeter will display a "tool-tip" pop-up with fire name. On mobile devices, click or tap the perimeter to see full metadata.

Soil Burn Severity Data/Map published by USGS and USFS – A dataset or map product that identifies fire-induced changes in soil and ground surface properties that may affect infiltration, runoff and erosion potential. These data are automatically downloaded from the "BAER Imagery Support Data Download" website linked below.

[WFIGS-Perimeter-daily]

This product represents the best available perimeters for recent and ongoing wildland fires in the United States. Currently this is set to all >100 Acres, but this is subject to change.

[WFIGS-Perimeters]

This product represents the best available perimeters for recent and ongoing wildland fires in the United States. It is produced by the Wildland Fire Interagency Geospatial Services (WFIGS) Group and provides authoritative geospatial data products under the interagency Wildland Fire Data Program. Hosted in the National Interagency Fire Center ArcGIS Online Organization (The NIFC Org), WFIGS provides both internal and public facing data, accessible in a variety of formats.
