What makes AQAST unique?

All AQAST projects connect Earth Science and air quality management: Involve active partnerships with air quality managers, have deliverable

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• State: TCEQ, MDE, Wisconsin DNR, CARB, Iowa DNR, GAEPD, GFC• Regional: LADCO, EPA Region 8 • National: EPA, NOAA, NPS

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 to educate Earth scientists on AQ needs• To hear about pressing AQ management issues, and determine how

AQAST can help – to-do list!

• Utility of satellites for long-term trend monitoring;

• Regional character of NOx pollution;

• NOx effective lifetime in models is too short.

AQAST Highlight: OMI observes NOx decrease from implementation of emissions control devices (ECDs) on power plants: 2005-2011

We analyzed the relationship between OMI NO2 columns and emissions from 55 power plants for 2005-2011. We found that OMI clearly detects the implementation of ECDs, though this relationship varies due to changes in the background levels of NO2 (e.g., from the decreasing mobile source), proximity to urban sources, magnitude of the emissions reduction, meteorology, etc.
