5. What makes AQAST unique? Broad mandate to serve the evolving needs of US air quality management o AQAST is self-organizing, defines its own projects in consultation with AQ managers o Focus is on quick response to AQ agencies at national/regional/state/local levels o All projects involve partnerships with AQ managers, application outcomes o Multi-member Tiger Teams tackle problems requiring coordinated activity o Communication with AQ managers is emphasized through multiple channels o Outreach to public is an additional important component Quick, collaborative, flexible, responsive to the needs of the AQ community http://www.aqast.org/ http://www.aqast-media.org/

6. Current AQAST Tiger Teams Web-enabled tools for AQ management decision support (Szykman, Spak) EPA, Iowa, San Joaquin Source contributions to O 3 and PM 2.5 pollution episodes across Eastern US (Holloway, Fiore) LADCO, MARAMA, OTC, Connecticut, Maine, Maryland, Missouri, New Hampshire, New York, Texas, Maricopa Dynamic inputs of Natural Conditions for Air Quality Models (Cohan) EPA, California, Texas Satellite NO 2 columns, NO x emissions, and air quality in North America (Streets) EPA, LADCO, Maryland Air quality reanalysis (Carmichael) EPA, CDC, California, Georgia, Maryland, Virginia, South Coast Satellite signatures of emissions associated with US oil & gas extraction (Thompson) BLM, EPA Region 8, MARAMA, CenSARA, Colorado, Maryland, Oklahoma Evaluation of AQAST’s impact (Milford) EPA, WRAP, San Joaquin Selected through on-line polling of AQ management community (62 responses) and subsequent review by AQ managers’ panel (Pat Dolwick, EPA; Tom Moore, WRAP; Susan Wierman, MARAMA; Paul Miller, NESCAUM)
