README notes for GEM-MACH AMAP type 0 data files
Model (GEM-MACH Arctic configuration, GEM-MACH v2.5+): pan-Arctic LAM @15-km horizontal resolution, 80 hybrid levels from surface to 0.1 hpa; ADOM2 chemistry mechanism (gaseous and aqueous phase chemistry); ISOROPIA inorganic heterogeneous chemistry; sectional representation for aerosol size distribution (12 size bins from 10 nm to 40.96 um in diameter); 8 PM chemical components (sulphate, nitrate, ammonium, sea-salt, secondary organic matters, primary organic matters, elemental carbon, crustal materials); internally mixed.
Anthropogenic Emissions: 2015 Canadian national Air Pollution Emission Inventories and 2016 US National Emission Inventories for North American portion of the domain, and ECLIPSE v6b 2015 baseline emissions for outside North America. 
Wildfire emissions: 2015 North American Wildfire emissions processed using the Canadian Forest Fire Emission Prediction System (CFFEPS) (Chen et al., 2019; https://doi.org/10.5194/gmd-12-3283-2019). 
Biogenic and sea-salt emissions: Biogenic emissions are calculated based on BEIS version 3.09 with BELD3-format vegetation land cover; sea salt emissions are computed based on Gong et al. (2003; https://doi.org/10.1029/2001JD002002).
AMAP type 0 simulation was conducted for the year 2015; time step: 450 s; raw model output frequency: hourly (instantaneous).
