North American acetone sources determined from tall tower measurements and inverse modeling
Atmos Chem Phys 2013, 2; 13(6), 2; 10.5194/acp-13-3379-2013 - 25 March 2013
Abstract
We apply a full year of continuous atmospheric acetone measurements from the University of Minnesota tall tower Trace Gas Observatory (KCMP tall tower; 244 m a.g.l.), with a 0.5° × 0.667° GEOS-Chem nested grid simulation to develop quantitative new constraints on seasonal acetone sources over North America. Biogenic acetone emissions in the model are computed bas

Chemical transport model simulations of organic aerosol in southern California: model evaluation and gasoline and diesel source contributions
Atmos Chem Phys 17(6), 1; 10.5194/acp-17-4305-2017
Abstract
Gasoline- and diesel-fueled engines are ubiquitous sources of air pollution in urban environments. They emit both primary particulate matter and precursor gases that react to form secondary particulate matter in the atmosphere. In this work, we updated the organic aerosol module and organic emissions inventory of a three-dimensional chemical transport model, the Community Multi
