Wildfires emit vast amounts of trace gases and aerosols that significantly alter atmospheric composition, impact air quality, and influence climate dynamics. These emissions include photochemically reactive compounds that could modify tropospheric ozone levels, degrading air quality in both immediate and distant regions downwind. Furthermore, wildfire-generated aerosols affect solar radiation, modify cloud formation, and serve as sites for heterogeneous chemical reactions. Understanding the intricate chemistry within wildfire plumes—ranging from emission sources to long-range transport over continents—is crucial for improving predictions of air quality and assessing the broader environmental and health impacts. This session will focus on recent research exploring the chemical and physical processes occurring within wildfire plumes, considering both short- and long-range transport dynamics. Contributions that investigate the interaction of wildfire smoke with meteorological systems, the role of plumes in altering air quality across regions, and the potential for climate feedback are particularly encouraged. We welcome studies utilizing field measurements, satellite observations, and advanced computational models to improve our understanding of the impacts of wildfires on air quality, climate, and public health in the context of the increasing frequency and intensity of these events worldwide.
