Session 1C Agriculture – Atmosphere Interactions

Monday, 29 January 2024: 8:30 AM-10:00 AM
339 (The Baltimore Convention Center)
Host: 26th Conference on Atmospheric Chemistry

Agriculture influences Earth’s atmosphere by enhancing emissions of reactive and greenhouse gases, altering the land surfaces available for dry deposition of pollutants, and modifying the cycling of carbon, nitrogen, water, and energy. At the same time, atmospheric composition affects agriculture via increased exposure to phytotoxic gases like ozone and aerosol-induced changes in solar radiation and precipitation. These connections range in scale from the process-level to the global carbon and nitrogen cycles. The emissions and sequestration of gases like NOx, NH3, N2O, CO2, and CH4 from agriculture are an important emerging area of atmospheric and climate science.

This session invites presentations on all aspects of the coupled agrosphere-atmosphere system, including laboratory and field studies of key processes, model-based investigations of multi-system interactions and feedbacks, analysis of satellite remote sensing products, validation of emissions inventories, and extensions to economic, air quality, and climate impacts. Topics can include but are not limited to: emissions ratios, eddy covariance fluxes, gas-aerosol partitioning, aerosol composition, deposition, sequestration, fluctuations with meteorological conditions, impacts to sensitive ecosystems, and the usage of data to understand the intersectionality of food, energy, land, clean air, policy, and environmental justice.
