Ozone total column and surface comparisons during differing meteorological conditions at Edgewood, MD during summer 2011

Chemical and meteorological measurements were taken during 01 July - 31 July, 2011 in the Mid-Atlantic region as a part of the first year of NASA's DISCOVER-AQ (Deriving Information on Surface Conditions from COlumn and VERtically Resolved Observations Relevant to Air Quality) campaign. The main objective of the project is to relate total column amounts to surface amounts of constituents related to air quality for the improvement of satellite interpretation and diagnosis of surface pollution. The Nittany Atmospheric Trailer and Integrated Validation Experiment (NATIVE) trailer was deployed to Aberdeen Proving Ground in Edgewood, MD during the campaign to provide in-situ, ground-based air quality measurements. NATIVE surface data, as well as coincident free-flying and tethered balloon ozone profiles are compared with observations from a NASA P3B aircraft performing profile spirals directly over the Edgewood site. Phenomena such as bay breeze circulations and their effect on surface and column pollution amounts are also investigated.
