4. What makes AQAST unique? All AQAST projects connect Earth Science and air quality management:  Involve active partnerships with air quality managers, have deliverable application 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 4

5. Scope of current AQAST projects AQ agency Local: RAQC, BAAQD, SJVAPCD, CDPHE States: California, Georgia, Iowa, Maryland, Oklahoma, Texas, Virginia, Wisconsin Regional: LADCO, CenSARA, MARAMA National: EPA, NOAA, NPS, BLM 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

6. 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 educate Earth scientists on AQ needs To hear about pressing AQ management issues, and determine how AQAST can help – to-do list! To discuss specific issues facing east Texas, including first results from the DISCOVER-AQ aircraft campaign 5 th AQAST meeting at U. Maryland (June 9-11, 2013)

7. AQAST Highlight: Primer on using satellite data for air quality emission estimates 7 Year 2 Tiger Team activity involving nine AQAST PIs working with AQ managers

8. AQAST Highlight: Ammonia emissions and nitrogen deposition in the US 2006 2050 Present and future (RCP) US emissions US ammonia emission inventories Nitrogen deposition in US national parks Improved understanding of ammonia emissions in US by adjoint inversion of satellite and deposition data Demonstration of broad N exceedance problem in national parks, driven by ammonia in future Presently working with EPA and NPS in evaluation of secondary nitrogen oxides standard AQAST PIs: Henze, Jacob 8 NO x NH 3

9. AM3 (~2°x2°) GEOS-Chem (½°x⅔°) Fourth-highest North American background MDA8 O 3 in model surface layer between Mar 1 and Aug 31, 2006 ppb AQAST Highlight: N American background ozone estimated from two different global models (simulations with N. American anth. emissions set to zero) Large intermodel difference in background ozone over Intermountain West has important implications for AQ management strategies Higher background: More exchange with surface? Larger stratospheric influence? 35 42 50 57 65 High AM3 bias in EUS; caution on N. Amer. Background here! Excessive lightning NO x in summer J. Oberman AQAST PI: Fiore
