Forest fires in a changing climate and their impacts on air quality

► We investigate the impact of forest fires on air quality over Portugal under climatic scenario. ► we simulated reference and future climate change scenarios using the MM5/CHIMERE modelling system. ► The forest fire emissions were estimated using a standard methodology. ► Modelling results pointed out that future forest fire emissions will impact O3 and PM10. ► The highest increases are estimated over the north and centre of Portugal.
