What makes AQAST unique?
All AQAST projects connect Earth Science and air quality management: Involve active partnerships with air quality managers, have deliverable
application outcomesExpand 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 projectsAQ agency• Local: RAQC, BAAQD, SJVAPCD, CDPHE• States: California, Georgia, Iowa, Maryland, Oklahoma, Texas, Virginia, Wisconsin• Regional: LADCO, CenSARA, MARAMA• National: EPA, NOAA, NPS, BLM

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
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)

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
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
NOx
NH3
AM3 (~2°x2°) GEOS-Chem (½°x⅔°)
Fourth-highest North American background MDA8 O3 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?

High AM3 bias in EUS;caution on N. Amer. Background here!

AQAST Products
• GLIMPSE (Henze): fast screening tool for radiative forcing implications of AQ management strategies
• Operational AQ ensemble forecasts for Maryland (Thompson)
• WHIPS (Holloway): user-friendly processing of satellite data
1. Easily obtain useful data in familiar formatsCustom 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 concentrationsOne-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)
