AQAST members

  3. Pollution monitoring Exposure assessment AQ forecasting Source attribution Quantifying emissions External influences AQ processes Climate interactions satellites AQAST suborbital platforms models AQAST

  4. What makes AQAST unique? • All AQAST projects connect Earth Science and air quality management: • active partnerships with air quality managers with deliverables/outcomes • self-organizing to respond quickly to demands • flexibility in how it allocates its resources • INVESTIGATOR PROJECTS (IPs): members adjust work plans each year to meet evolving AQ needs • “TIGER TEAM” PROJECTS (TTs): multi-member efforts to address emerging, pressing problems requiring coordinated activity www.aqast.org: click on “projects” for brief descriptions + link to pdf describing each project • Tiger Team proposals currently under development (Y3, review in Sept) include: • Web-enabled AQ management tools • AQ reanalysis • Ensemble based AQ forecasting • Dynamical natural inputs for AQ models • Source attribution for O3 and PM events over EUS • Oil & gas emissions • Satellite-derived NOx emissions and trends

  5. 5 AQ agency SIP Modeling AQ processes Monitoring AQ-Climate Background IC/BC for AQ models Forecasting Emissions Future satellites • Local: RAQC, BAAQD • State: TCEQ, MDE, • Wisconsin DNR, CARB, • Iowa DNR, GAEPD, GFC • Regional: LADCO, EPA Region 8 • National: EPA, NOAA, • NPS Scope of current AQAST projects Theme 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 Earth Science resource

  6. 6 Semiannual AQAST meetings engage air quality managers Boulder (May 11), RTP (Nov 11), Wisconsin (Jun 12), CARB (Dec 12), Maryland (Jun 13) • Share knowledge and experience in using Earth Science data and tools for serving AQ management • Educate AQ managers in the use of Earth Science data and tools, and to educate Earth scientists on AQ needs • Hear about pressing AQ management issues, and determine how AQAST can help AQAST meeting at U. Maryland (June 9-11, 2013)

  7. AQAST Highlight: CO trends and NOx budgets in Maryland 7 • Utility of satellites for long-term trend monitoring; • Regional character of NOxpollution; • NOx effective lifetime in models is too short.

  8. 8 Wyoming DEQ/AQD used AQAST resources to issue an exceptional event demonstration package for an ozone exceedance at Thunder Basin, June 6, 2012 AQAST Highlight: Wyoming Exceptional Event Demonstration AQAST PI: Pierce

  9. 9 • Uncontrolled landfill liner fire within 5 miles of >150K people • 7.5 acres burned, May-June 2012 • 1.3 million shredded tires • Irritants + mutagens + SO2 + 5-80 µg/m3 PM2.5 • AQAST Nowcasting tool helped policymakers decide public health response & favorable conditions for fire intervention • WRF-Chem + GSI 3DVAR 72hr forecast assimilating MODIS data. • + AERMOD @ 100 m • + emissions factors from mobile monitoring by 3 groups • = New decision support toolkit for rapid public health response to urban toxic releases AQAST decision support for the Iowa Landfill Fire of 2012 AQAST PI: Carmichael

  10. 10 Nitrogen deposition in US national parks US ammonia emission inventories Present and future (RCP) US emissions Ammonia emissions and nitrogen deposition in the US NOx • 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 NH3 2050 2006 AQAST PIs: Henze, Jacob

  11. 11 Year 2 Tiger Team activity involving nine AQAST PIs working with AQ managers Primer on using satellite data for air quality emission estimates AQAST PI: Streets

  12. 12 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

  13. 13 • 1. Easily obtain useful data in familiar formats • Custom OMI NO2 “Level 3” products on any grid in netCDF with WHIPS (Holloway) • Annual NO2shapefiles - 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.
