Science for mitigation of agricultural trace gas emissions
Science for mitigation of agricultural trace gas emissions
Session ID#: 121830
Session Description:
Trace gas emissions, including volatile organic compounds (VOCs), ammonia (NH3), nitrogen oxides (NOx), nitrous oxide (N2O), and methane (CH4), from agriculture influence local and regional air quality and global radiative forcing. VOCs and NH3 contribute to formation of secondary organic aerosols which produce negative health impacts, affect albedo coverage, and enhance N deposition to ecosystems. CH4 and N2O emissions contribute to global warming, tropospheric ozone formation, and stratospheric ozone destruction. Despite their relevance, data and process understanding of these emissions are lacking. In order to effectively mitigate emissions, further work is needed to better understand the effect of management practices on emissions of multiple trace gases in tandem. We seek contributions that assess direct measurements of trace gas fluxes derived from agriculture, improve process understanding through laboratory experiments and models, and integrate top-down and bottom-up modeling to evaluate the impact of agriculture.
