What makes aqast unique

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

Semiannual aqast meetings

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!

Zoom over censara region annual ammonia emissions

Optimized inventory from the inversion has 200 km monthly resolution;

MASAGE inventory has 50 km resolution

Zoom over CenSARA region (annual ammonia emissions)


Detailed masage emissions breakdown for nebraska

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?

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]


Detection of anthropogenic voc emission hotspots by oversampling of satellite omi formaldehyde data

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?
