Project Type: Specific Cooperative Agreement

End Date: Feb 28, 2009

Objective:
The objectives of this research are to 1) develop new methods and improve existing methods to measure emissions of particulate matter and gases from animal feeding operations; 2) develop and determine the effectiveness of management practices and control technologies to reduce emissions; and 3) Develop tools to predict emissions and their dispersion across a range of animal production systems, management practices, and environmental conditions.

Approach:
The approach to address these objectives is multi-faceted and includes a range of experimental and theoretical studies. Studies will be conducted to determine the particulate emission from livestock and cropping systems as a model system to evaluate micrometeorological models applicable to limited fetch conditions. These observations will be used to refine existing dispersion models for more realistic conditions in agriculture. Studies will be conducted on the development of technologies that can be used to quantify the ambient levels of gases in the atmosphere surrounding livestock, processing facilities, and cropping systems. These studies will require the development and evaluation of new instruments with an ability to quantify low concentrations of gases and particulate material.
