  1. LADCO and AQAST: one regional air quality manager’s perspective Donna Kenski Lake Michigan Air Directors Consortium Houston AQAST Meeting, Jan 15-17, 2013

  2. About LADCO • Purpose: • provide technical assessments for and assistance to its member states on air quality; • provide a forum for its member states to discuss air quality issues. • Focus is on ozone, fine particles, regional haze and their precursors • Geographic focus is our member states and surrounding areas that impact them

  3. Technical Support • Schedule dictated by regulatory requirements • Four components: • Emissions inventory development, • Photochemical modeling, • Data analysis, • Monitoring and special projects • All work is done in collaboration with the states, via workgroups

  4. Average Maximum Temperature Departure from Mean, June-August 2005 2002 2003 2004 2009 2006 2007 2008 2013 2010 2011 2012

  5. Improving InventoriesInventory perspective : Mark Janssen • Many studies have promised to improve inventories but often those promises do not connect with the products necessary to improve inventories. • Products must have a clear path to integration with inventories. • Researchers need to work with inventory developers to translate results into appropriate emission inventory inputs

  6. Remote sensing can make it worse. • Current NEI has “broken” satellite-based inventory for agricultural burning in Midwest. • Analysis sees freshly plowed black Midwest soil and calls it new burn. 10% of Indiana ag land burning? • EPA adopts national inventory,Midwest states now must wrestle those bad numbers out of NEI. 24,000 TPY PM25 IowaTwice onroad/industrial COMBINED!

  7. Issues, Challenges, Questions • Need to speak the same language; satellite data streams are very rich but hard to translate into data that can be used to modify inventories. Tracey’s calls with AQ mgrs seems like a good start. • Great AQAST progress on NOx point sources; can we distinguish or quantify NOx from cars versus trucks and onroadvsoffroad? • Agricultural ammonia (summer and winter) ; decreasing SOx and NOx make NH3 even more important. • Organic carbon (worst model performance): • Refineries; many studies have shown inventories significantly underestimate VOCs from these and similar sources, including Lei Zhu yesterday • Temporal and spatial patterns of SOA formation • New oil and gas development (spatial, magnitude) • Residential wood combustion (spatial, temporal, magnitude) • NOxdisbenefit in urban areas; can it be seen in the satellite data? • Visibility: Can satellite data help us quantify transport between states and across national borders or oceans, distinguish between natural and anthropogenic carbon sources • Can satellite data improve meteorological model performance?
