Chemical transport modeling of wildfire smoke PM2.5 in Canada: An evaluation of major emission inventories

This talk will present recent work to implement the Canadian/Global Forest Fire Emissions Prediction System (C/GFFEPS) into the chemical transport model GEOS-Chem in order to predict fine particulate matter concentrations (PM2.5) in Canada during the wildfire season. The C/GFFEPS inventory was used within GEOS-Chem to simulate PM2.5 concentrations in Canada for 2019 and 2021, and the modeled concentrations were compared against field observations. The computer simulations accurately represent the transport of wildfire smoke opening the door to further modeling studies on the environmental impact of wildfire smoke in Canada. In general, C/GFFEPS shows improved performance for predicting PM2.5 and AOD against other established wildfire emission inventories
