Agriculture, forest, and range production practices have increasingly become subject to state and federal regulations that are meant to protect air resources. The long-term (10 year) goals of this program are: a) develop emission data for agriculture, forest, and range production practices that will lead to emission reduction targets that will significantly improve air quality and protect human and environmental health; b) develop mitigation strategies that will increase adoption of best management practices to reduce agricultural emissions; and c) improve understanding of odor, gases, and particulate matter (PM) measurement, production, flux, fate and transport that will lead to a better understanding of the environmental fate of emissions.
