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

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
5th AQAST meeting at U. Maryland (June 9-11, 2013)

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

8. AQAST Highlight: Ammonia emissions and nitrogen deposition in the US
US ammonia emission inventories
Nitrogen deposition in US national parks
2006
2050
Present and future (RCP)
US emissions
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
NOx
NH3
AQAST PIs: Henze, Jacob

9. AQAST Highlight: Fourth-highest North American background MDA8 O3
N American background ozone estimated from two different global models (simulations with N. American anth. emissions set to zero)
Fourth-highest North American background MDA8 O3
in model surface layer between Mar 1 and Aug 31, 2006
AM3 (~2°x2°)
GEOS-Chem (½°x⅔°)
Higher background:
More exchange with surface?
Larger stratospheric influence?
High AM3 bias in EUS;
caution on N. Amer. Background here!
Excessive lightning NOx in summer
ppb

Operational AQ ensemble forecasts for Maryland (Thompson)
WHIPS (Holloway): user-friendly processing of satellite data

11. OMI NO2 KML in SARP flight planning
AQAST progress toward an OMI AQ management toolkit: AQ managers can now…
1. Easily obtain useful data in familiar formats
Custom OMI NO2 “Level 3” products on any grid in netCDF with WHIPS (Holloway)
Annual NO2 shapefiles - OMI & CMAQ on CMAQ grids (AQAST Tiger Team)
Google Earth
2. Find easy-to-use guidance & example scripts for understanding OMI products and comparing to simulated troposphere & PBL concentrations
One-stop user portal (Holloway & AQAST Tiger Team)
OMI NO2 & SO2 guidance, field campaign example case studies (Spak & AQAST Tiger Team)
3. Obtain OMI observational operators for assimilation & emissions inversion in CMAQ
NO2 in GEOS-Chem  CMAQ (Henze, Pye)
SO2 in STEM  CMAQ (Spak, Kim)
O3 in STEM  CMAQ (Huang, Carmichael, Kim)
