AeroCom is an open international initiative of scientists interested in the advancement of the understanding of global aerosol properties and aerosol impacts on climate, weather, and air quality. A central goal is to more strongly tie and constrain modeling efforts to observational data from satellite, ground-based, and aircraft observations. Major elements for exchanges between data and modeling groups are annual meetings of AeroCom together with the satellite-data-oriented initiative AeroSAT. The AeroCom/AeroSAT Conference 2023 will be held in Richland, Washington, with virtual components.
