Vegetation fires emit large quantities of trace gases and aerosols, which influence atmospheric composition as well as the chemical and physical processes that reshape air quality and the climate system. For example, the photochemically reactive compounds in wildfire, agricultural or prescribed burning smoke plumes can enhance tropospheric ozone to have significant impacts on air quality at local and downwind locations. Fire-generated aerosol particles can also impact radiation and provide surfaces for heterogeneous processes that modify the chemistry. The goal of this session is to solicit recent studies that advance our understanding and interpretation of atmospheric chemical and physical processes occurring in fire emission plumes as well as their consequences on air quality, climate, and health under the changing fire regimes we see in many parts of the world. We invite presentations covering small- to large-scale studies and involving computational modeling and/or measurements.
