AQAST Semiannual Meetings

AQAST meetings are held on a semiannual schedule and bring together team members, air quality managers, and research and applications partners. Our last meeting was held on January 15-17, 2014 at Rice University in Houston. You can access the agenda and presentations from that meeting here.

7th AQAST Meeting (AQAST7): June 17-19, 2014 at Harvard University

The next AQAST meeting (AQAST7) will be held June 17-19, 2014 (Wednesday-Friday) at Harvard University in Cambridge, MA, hosted by Dan Cohan. The meeting is free and open to the public. Air quality managers are especially encouraged to participate. Go to the meeting website for more information and to register. Indicate when you register if you would like to give a presentation. We look forward to seeing you in Cambridge in June!

AQAST Highlights

AQAST Special Issue of Environmental Manager

Environmental Manager, the monthly magazine of the Air & Waste Management Association, devoted its February 2014 issue to a presentation of AQAST activities in service of air quality management. The issue features an AQAST overview and six feature articles written by AQAST members. Access the full issue here.

Q&A Session with Johnson County (Iowa) AQ managers

AQAST member Scott Spak led a Q&A session on Johnson County air quality, recent trends, and regulatory updates with the Joint Meeting of the Johnson County Boards of Directors and Public Health, Iowa City, October 23, 2013.
