AMAP SLCF EG Pan-Arctic Fire Emissions Model

Custom pan-Arctic open biomass burning emissions model for the year 2018 using Suomi-NPP VIIRS active fire from day and night detections (Oliva and Schroeder, 2015). Each detect was assumed to completely burn each 375 m2 pixel. A ‘best-guess’ land cover was created, from three different land cover products. The 750 m VIIRS Surface Type land cover product (Zhang et al., 2018) was used for North America, Greenland, and the Russian Federation, augmented by the revised 1 km Circumpolar Arctic Vegetation Map (Raster CAVM; Raynolds et al., 2019). For Norway, Sweden, and Finland, the 10 m Land Cover Map of Europe 2017 from the Sentinel-2 Global Land Cover Project (Gromny et al., 2019) was used. All land cover maps were reclassified into the International Geosphere-Biosphere Program (IGBP) classes for ease of emission calculations. Fuel loadings and combustion completeness were taken from Van Leeuwen et al. (2014), with tundra values used for Greenland. Emission factors were taken from Akagi et al. (2011), with updates from Andreae (2019). Atmospheric species include black carbon, methane, and PM2.5.
