AQAST Newsletter, October 2013

Welcome to the October 2013 Newsletter of the NASA Air Quality Applied Sciences Team (AQAST). AQAST is a team of atmospheric scientists serving air quality management needs through the use of Earth Science data and tools. We conduct a wide range of projects in partnership with air quality agencies at the local, state, regional, and national levels.

This newsletter keeps you up to date on AQAST activities. The AQAST website has more comprehensive information. Also follow us on Twitter at @NASA_AQAST. To inquire about specific projects or request assistance please contact any AQAST member, team leader Daniel Jacob, or team deputy leader Tracey Holloway.

This newsletter was produced by Daniel Jacob (AQAST leader) and Bob Yantosca (AQAST webmaster). Subscribe/unsubscribe by email to Bob Yantosca.. Access previous newsletters here.

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 June 4-6 at the University of Maryland and you can access the agenda and presentations from that meeting here.

6th AQAST Meeting (AQAST6): January 15-17, 2014 at Rice University

The next AQAST meeting (AQAST6) will be held January 15-17, 2014 (Wednesday-Friday) at Rice University in Houston, hosted by AQAST member 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 Houston!

AQAST Project Highlights
