Circumpolar Fire Polygons with NBR, dNBR, RdNBR Metrics and Ecoregions, 1986-2020

Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.3334/ornldaac/2477

This dataset contains polygons of retrievable fire boundaries across the circumpolar region attributed with pre-fire and post-fire normalized burn ratio (NBR), differenced normalized burn ratio (dNBR), relative differenced normalized burn ratio (RdNBR), and terrestrial ecoregions.

Description

The dataset is separated into three regions: North America, Europe, and Asia; each saved in an appropriate projection and with the years of data available from that region.

Historical fire perimeters were available from 1986 to 2020 for North America. Fires from Europe and Asia were available from 2003 to 2016. Polygon geometries were simplified and processed to represent each fire with a single polygon.

Google Earth Engine was used to calculate the mean pre-fire and post-fire NBR both within the polygon and in a buffer around the fire. The buffer values were used to adjust NBR values to account for differences in reflectance between image acquisition dates not related to the fire. The data are provided in GeoPackage format.
