Concentrated animal feeding operations (CAFOs) are prominent sources of ammonia (NH3) and fine particulate matter (PM2.5) emissions and thus have a significant impact on air quality, human health, and climate. However, there are considerable uncertainties associated with NH3 and PM2.5 emissions from agriculture dominated regions, limiting our predictive capability to use atmospheric models to assess the impacts of agricultural activities on air quality and climate. Moreover, it remains elusive how atmospheric NH3 is changing and how such a change will affect air quality from local to regional scale.
Proposed solution. We propose a 3-year multi-institutional integrated atmospheric composition and air quality project to utilize NASA Earth Science observations (satellite, sub-orbital and ground) to support air quality modeling and analysis of NH3 and PM2.5 change associated with intensive agriculture.
The primary objective of this study is to address three science questions: 1) How are agricultural emissions changing in the past decade? 2) How well can the 3-D chemical transport models be used to study the emissions, transformation and removal of NH3 and PM2.5 over agriculture-dominated regions? 3) How can NASA Earth observations be utilized to improve agricultural emissions, constraint model processes, and verify model prediction? To this end, we propose the following activities to be conducted by a team of emission scientists, Earth scientists and air quality modelers:
A National Workshop on Agricultural Air Quality, Principal Investigator and Project Scientist - Viney P. Aneja; January 1, 2005 - December 31, 2009 ($394,868)
A 3 –year multi- institutional program to organize a National Workshop on Agricultural Air Quality in collaboration with the Ecological Society of America during FY 2006 in and around Washington DC. The project team is multidisciplinary. It comprises of air quality, agricultural, and environmental scientists. The workshop has the express purpose to create a document that will be used to improve agricultural air quality emission inventories for air pollutants, to recommend changes and improvements in measurement technologies and monitoring methodologies, modeling and transport of odor and air pollutants and recommend best production practices to mitigate air pollutant emissions. Agricultural Air Quality is an important and emerging research topical area with significant multidisciplinary components. Agriculture, forest, and range production practices have increasingly become subject to state and federal regulations that are meant to protect air resources. In many instances, data do not exist or are not representative of agricultural industries for the purpose of estimating emissions to the atmosphere of regulated pollutants or of public nuisances such as odors and fugitive dust.
