Impacts of 2023 Canadian Wildfire Emissions on Solar Power Over North America and Europe

The current repository contains inputs, products, and codes associated with an upcoming study by Rosu et al. titled "Smoke from Canada’s extreme 2023 wildfires caused 2.8% drop in solar power generation and cost energy systems over almost one two billion dollars". This study investigates the short-term, large-scale impacts of the 2023 Canadian wildfire emissions on solar power generation in Canada, the USA and Europe using the Earth System Model EC-Earth3 (EC-Earth3-AerChem configuration - FORCes branch [1-2]. For this work, two sets of simulations were conducted, one considering fire emissions (NX) and one without (NC). Regarding the emissions used, the GFAS wildfire emission dataset was applied (refer to Kaiser et al. [3] and to [4]), while for the rest of the emissions, i.e., natural and anthropogenic, refer to van Noije et al. [2] and to [5]. References [1] Döscher et al.
