AQAST members

  4. On AQAST website (google AQAST), click on “members” for list of 19 members and areas of expertise

  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 quicklyto demands Quick, collaborative, flexible, responsive to the needs of the AQ community www.aqast.org

  6. 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

  7. Semiannual AQAST meetings Boulder (May 11), RTP (Nov 11), Wisconsin (Jun 12), CARB (Dec 12), Maryland (Jun 13); AUSTIN JANUARY 15-17 2014! • 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, educate Earth scientists on AQ needs • Hear about pressing AQ management issues, and determine how AQAST can help We hope to see you in Austin! http://acmg.seas.harvard.edu/aqast/meetings/2014_jan Local host: Dan Cohan (Rice University) AQAST meeting at U. Maryland (June 9-11, 2013)

  8. ARSET/AQAST at CMAS • Twice-yearly AQAST meetings • AQAST workshops and training sessions • AQAST representation at AQ meetings • Ozone garden network • Website, quarterly newsletter (click here to subscribe) • Media center, Twitter AQAST communicationsand outreach St. Louis ozone garden NO2 trends lenticular

  9. Optimizing NH3 emissions in US (and globally) by adjoint inversion of 2005-2008 NH4+ wet deposition flux data NADP data (circles) and GEOS-Chem model after adjoint inversion April: fertilizer July: livestock kgN ha-1 month-1 GEOS-Chemadjoint Chemical transport model (GEOS-Chem) NH3 emission NH3(g)/NH4+ wet dry agriculture, other sources Paulot et al. [submitted]

  10. Optimized ammonia emissions …and new MASAGE bottom-up ammonia emission inventory US EU E Asia x 0.5 8.4 (China) 2.8 3.1 8.4 2.7 2.9 natural crops other anthro livestock Paulot et al. [submitted]

  11. Seasonality of ammonia emissions in different regions Paulot et al. [submitted]

  12. Optimized inventory from the inversion has 200 km monthly resolution; MASAGE inventory has 50 km resolution Zoom over CenSARA region (annual ammonia emissions)

  13. Detailed MASAGE emissions breakdown for Nebraska Total emissions of 121 Tg N yr-1 (2005-2008 average) What product(s) would be of particular value to CenSARA members?

  14. Using satellite observations of methane to constrain US methane emissions methane emissions SCIAMACHY methane (Jul-Aug 2004) adjoint inversion ppb 1700 1800 Total US anthropogenic emissions (Tg a-1) EDGAR v4.2 26.6 EPA 28.3 This work 32.7 Wecht et al. [in prep]

  15. Current satellite observations of methane available from GOSAT Correction factors to EDGAR v4.2 from preliminary inversion GOSAT data, May-June 2010 • GOSAT data are sparser than SCIAMACHY (RIP 2005) but of good quality; TROPOMI (2015 launch) will give full daily coverage • We are presently working to squeeze all the information we can get from the GOSAT data; need stakeholder interest to focus our efforts • Is this of interest to CenSARA? Can we develop collaborations? Turner et al. [in progress]

  16. Detection of anthropogenic VOC emission hotspotsby oversampling of satellite (OMI) formaldehyde data Res=0.04o, bandwidth=36km • Data can be used to evaluate reactive VOC emissions in regional AQ models • Unexpected hotspots can be identified (oil/gas operations?) • Can cover CenSARA region if there is interest – or focus on suspected hotspots?
