5. What makes AQAST unique? All AQAST projects connect Earth Science and air quality management:  Involve active partnerships with air quality managers, have deliverable outcomes  Expand relationships through meetings, online tools, newsletters AQAST has flexibility in how it allocates its resources  Members adjust work plans to meet evolving air quality needs  Multi-member “Tiger Teams” are organized each year to address newly emerging, pressing problems requiring coordinated activity  AQAST is self-organizing and can respond quickly to demands Quick, collaborative, flexible, responsive to the needs of the AQ community www.aqast.org

Scope of current AQAST projects AQ agency Local: RAQC, BAAQD State: TCEQ, MDE, Wisconsin DNR, CARB, Iowa DNR, GAEPD, GFC Regional: LADCO, EPA Region 8 National: EPA, NOAA, NPS Theme SIP Modeling AQ processes Monitoring AQ-Climate Background IC/BC for AQ models Forecasting Emissions Future satellites Earth Science resource Satellites: MODIS, MISR, MOPITT, AIRS, OMI, TES, GOES, GOME-2 Suborbital: ARCTAS, DISCOVER-AQ, ozonesondes, PANDORA Models: MOZART, CAM, AM-3, GEOS-Chem, RAQMS, STEM, GISS, CMIP

7. Goals of this meeting To share knowledge and experience in using Earth Science data and tools for serving AQ management To educate AQ managers in the use of Earth Science data and tools, and to educate Earth scientists on AQ needs To hear about pressing AQ management issues, and determine how AQAST can help – to-do list! AQAST4 at California Air Resources Board – December 2012

8. AQAST Highlight: CO trends and NO x budgets in Maryland MOPITT satellite instrument EPA site (Greenbelt) CMAQ evaluation with OMI NO 2 down wind upwind from Baltimore UMD aircraft during DISCOVER-AQ Canty, Salawitch, Dickerson, et al. Utility of satellites for long- term trend monitoring; Regional character of NO x pollution; NO x effective lifetime in models is too short.

9. AQAST Highlight: OMI observes NO x decrease from implementation of emissions control devices (ECDs) on power plants: 2005-2011 B. Duncan, Y. Yoshida, L. Lamsal, B. de Foy, D. Streets, Z. Lu, N. Krotkov, and K. Pickering Crystal River ECDs implemented June 2009 Crystal River facility, Florida x10 15 molec/cm 2 OMI NO 2 shows that regional levels decreased Tampa We analyzed the relationship between OMI NO 2 columns and emissions from 55 power plants for 2005-2011. We found that OMI clearly detects the implementation of ECDs, though this relationship varies due to changes in the background levels of NO 2 (e.g., from the decreasing mobile source), proximity to urban sources, magnitude of the emissions reduction, meteorology, etc. 2005 2011

10. AQAST Highlight: Wyoming Exceptional Event Demonstration Wyoming DEQ/AQD used AQAST resources to issue an exceptional event demonstration package for an ozone exceedance at Thunder Basin, June 6, 2012 R.B. Pierce et al.
