These materials are suitable for widespread use, but were developed especially to assist educators in their classrooms and educational programs. These include fact sheets suitable for handouts. Additional materials vary by topic but may include archived webinars, videos, technology summaries, photos, or presentation slides.

National Air Quality Site Assessment Tool (NAQSAT) – a confidential, non-quantitative way to look at different management practices and see what impacts those changes are likely to have on the gases and odors emitted from your farm. Related: NAQSAT for swine and poultry | beef and dairy
Feedlot Air Emissions Treatment Cost Calculator – a spreadsheet for calculating the costs of various technologies that reduce odors and air emissions from your farm
These webinars are one-hour total although all have separate segments that average 15 minutes. The speakers are national experts on the topic presented. Archives also include links to download each segment and presentation slides. The videos are shorter (5-13 minutes) include national experts as well as producer perspectives.
National Air Emissions Monitoring Study (NAEMS)
This project concluded in 2010 and represents the largest coordinated effort to ever measure air emissions from animal facilities.
Mono-slope and other types of bedded beef barns are a relatively new housing system becoming popular in the upper Midwest for a variety of reasons–mostly driven by water quality concerns. What are the air emissions from these barns and how does that compare with what we know about traditional open lots? A recently-completed tri-state research project examined these questions. More…

This information was originally developed by the Air Quality Education in Animal Agriculture (AQEAA) project. This team included more than 50 individuals from across the country with expertise in many aspects of air quality and animal agriculture. These materials were produced with financial support from the National Research Initiative Competitive Grant 2007-55112-17856 from the USDA National Institute of Food and Agriculture.
