This data set provides estimates of daily burned area, carbon emissions and uncertainty, and daily fire ignition locations for boreal fires in Alaska, USA, and the Yukon and Northwest Territories, Canada. The data are at 500-m resolution for the 18-year period 2001 through 2018. Burned area was retrieved from combining fire perimeter data from the Alaskan and Canadian Large Fire Databases with surface reflectance and active fire data from the Moderate Resolution Imaging Spectroradiometer (MODIS) Collection 6. Per-pixel carbon consumption was estimated based on a statistical relationship between field estimates of pyrogenic consumption and several environmental variables. To derive the carbon consumption estimates, the approach from Alaskan Fire Emissions Database (AKFED) was updated and extended for the period 2001 to 2018. Fire weather variables, temperature and the drought code complemented remotely sensed tree cover and burn severity as model predictors. Fire ignition location and timing were extracted from the daily burned area maps.
