Description:

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, and variability is exacerbated by acute and chronic environmental stressors such as extreme weather, increasing temperatures, and prolonged drought. 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, and impacts to sensitive ecosystems. Given this year’s theme of “Towards a Thriving Planet”, we particularly welcome presentations that emphasize the sharing of knowledge, tools, and techniques to understand the intersectionality of food and energy production, resource management, policy, and economic impacts in a changing climate.
