Natural aerosols and gases play a key role in the Earth System. They link terrestrial, atmospheric, and ocean processes and understanding changes in their emission and deposition is essential for assessing the climate response to human activities. This session aims to evaluate the current state of knowledge on aerosols and gases from natural sources, such as wildfires, dust, volcanoes, sea spray, and biogenic emissions, and to identify their impacts on climate, biogeochemistry, and society across diverse spatial and temporal scales. Topics of interest include, but are not limited to: environmental drivers of natural aerosol and gas emissions; source apportionment; evolution of natural aerosol contribution to atmospheric composition; direct and indirect radiative effects; processes governing aerosol deposition and gas transfer at the air-sea and land-air interfaces; past and future changes to aerosol and gas fluxes; nutrient and contaminant exchange and impacts on ecosystems; and innovative observational approaches and modeling frameworks.
