Paired Vegetation and Soil Burn Severity Metrics and Associated Climate, Weather, Topographical, and Land Cover Attributes

Abstract

<p>This dataset pairs differenced Normalized Burn Ratio (dNBR) and soil burn severity (SBS) for 254 large (>400 ha in size) fires across the western US. Dataset also includes climate, weather, topography, physical and chemical soil characteristics, and land cover attributes of each burned pixel at the time of fire. This effort provided a table of 16.3 million burned pixels and their associated characteristics including dNBR, SBS, and 94 biological and physical covariates. After removing correlated features, the final data includes 18 fire covariates namely: dNBR, elevation, slope, aspect, land cover type, wind speed, energy release component, vapor pressure deficit, annual precipitation, and annual average daily max temperature, as well as the clay, sand and silt content of the soil and volumetric fraction of coarse fragments and soil organic carbon content. We also included spatial coherence metrices for dNBR, including DVAR, SHADE and SAVG. This data is provided as CSV files in Xtrain, Xvalidation, Xtest, as well as Ytrain, Yvalidation, and Ytest; in which X files (model input) provide all features except for SBS and Y files (model output) include SBS.</p><p>We also provided this data for an additional 16 large fires across the western US ("Extra Test" folder, including Dataset – X file – and Label – Y file).</p><p>Finally, the trained XGBoost model to translate dNBR to SBS using the associated features is also provided in this folder.</p><p><strong>Data Sources:</strong></p><p>Burn severity: https://burnseverity.cr.usgs.gov/products/baer  </p><p>Weather and climate: http://thredds.northwestknowledge.net:8080/thredds/catalog/MET/climatologies/dailyClimatologies_1981_2010/catalog.html</p><p>https://developers.google.com/earth-engine/datasets/catalog/IDAHO_EPSCOR_GRIDMET</p><p>Land cover: https://developers.google.com/earth-engine/datasets/catalog/USGS_NLCD_RELEASES_2020_REL_NALCMS</p><p>Soil: https://gee-community-catalog.org/projects/isric/</p><p>Topography:https://developers.google.com/earth-engine/datasets/catalog/USGS_3DEP_10m </p&gt
