Session Proposal: Contribution of Natural Aerosols to Uncertainty in Aerosol Climate Forcing (AGU25)

A045
Contribution of Natural Aerosols to Uncertainty in Aerosol Climate Forcing

Session ID#: 252740

Session Description:
Understanding the role of natural aerosols in the atmosphere is essential for assessing anthropogenic aerosol forcing and the future climate response to human activities.  Our session intends to assess the state-of-the-science knowledge on aerosols and gas precursors from natural sources, e.g. wildfires, dust, volcanoes, sea spray, terrestrial and marine biogenic sources, and identify future directions to reduce uncertainty in their emissions, climate effects, and impact on the anthropogenic forcing. We encourage submissions that use models and measurements across spatial scales and consider pre-industrial, present, or future perspectives. Interests are, but not limited to: Process-level understanding of environmental drivers of natural aerosol and precursor emissions. Source apportionment of particles between natural and anthropogenic origins. Uncertainty in the life cycle and direct and indirect radiative effects of natural aerosols. Evolution and contribution of natural aerosols to atmospheric composition and deposition. Global feedbacks between natural aerosols and climate.
