Abstract:
The Wintertime Investigation of Transport, Emission, and Reactivity (WINTER) campaign used the NCAR/NSF C-130 aircraft to sample the composition of the lower troposphere over the Eastern United States between February 2 and March 13, 2015. The main scientific objectives of WINTER were to: 1) Characterize the chemical transformations of wintertime emissions via multiphase, nocturnal, and photochemical processes, 2) Assess the dominant mechanisms of secondary aerosol formation and quantify the geographical distribution of inorganic and organic aerosol types during winter, 3) Constrain wintertime emission inventories of key pollutants and characterize their export over the North Atlantic.
Here, we will present an overview of the WINTER observations obtained during 13 flights near major metropolitan areas (New York City, Washington D.C.-Baltimore, Philadelphia, Pittsburgh, Cincinnati, Atlanta), along the Ohio River Valley, and in aged pollution plumes over the Atlantic Ocean. We will analyze the WINTER observations using the GEOS-Chem chemical transport model in a nested-grid configuration with a 25 km horizontal resolution over N. America, focusing in particular on evaluating current anthropogenic emission inventories and the wintertime budget of reactive nitrogen species.
