Dry Deposition of Aerosols and Reactive Gases in our Earth System
Abstract
Identifying the drivers and impacts of air pollutants and short-lived climate forcers with global models relies on accurate representation of dry deposition, a primary removal pathway for aerosols and many reactive gases. Dry deposition happens when compounds are transported to the Earth’s surface via turbulence and are removed from the atmosphere by sticking to, or reacting with, surfaces. Dry deposition can also injure vegetation with implications for forest and crop health and regional-to-global water and carbon cycling. Dry deposition schemes have not been updated for decades in most global models used for predicting tropospheric composition and climate, and thus do not reflect current process-based knowledge. In my talk, I will discuss my work using observations and a hierarchy of models to advance mechanistic understanding of dry deposition, identify gaps in our understanding, and pinpoint the impacts of dry deposition on air pollution, ecosystems, and climate.
