1 3SAQS Network Assessment Till Stoeckenius, ENVIRON Three-State Air Quality Working Group Conference Call 19 December 2013

2 Recent Work Refinement of ozone site database – Additional state and FLM input – Identify sites currently expected to be operating 2014 – 2017 – Identify reason for site closures (funding vs logistical or other siting concerns) – Identify seasonal Forest Service monitors – Identify sites with co-located NOx Identify all sites which can be included in 3SAQS – Currently operating and expected to continue operating – Potentially being closed primarily due to funding issues 2

3 Recent Work (cont.) Additional map layers – Ozone non-attainment areas – Oil & Gas basin boundaries and total emissions by basin – Producing wells 2008, 2011, – RFD areas Correlation analysis Potentially underserved areas analysis 3

18 Potential Altitude Effects on O3 – Reduced upwind depositional losses – Increased potential for stratospheric intrusion impacts – Reduced impacts from upwind sources located at lower elevations – Others? Recent Forest Service Study: – Highest nighttime O3 at highest elevations – No correlation of daytime O3 with elevation Relationships Between O3 and Altitude 18
