Atmospheric Peroxyacetyl Nitrate (PAN): A Global Budget and Source Attribution
Fischer, E. V.; Jacob, Daniel James; Yantosca, Robert M.; Sulprizio, Melissa Payer; Millet, D. B.; Mao, J.; Paulot, F.; Singh, H. B.; Roiger, A.; Ries, L.; Talbot, R. W.; Dzepina, K.; Pandey Deolal, S. (Copernicus GmbH, 2014)Peroxyacetyl nitrate (PAN) formed in the atmospheric oxidation of non-methane volatile organic compounds (NMVOCs) is the principal tropospheric reservoir for nitrogen oxide radicals \((NO_x = NO + NO_2)\). PAN enables the ... -
Development of a grid-independent GEOS-chem chemical transport model as an atmospheric chemistry module for Earth System Models
Long, Michael Smither; Yantosca, Robert M.; Nielsen, J. E.; Keller, Christoph Andrea; da Silva, A.; Sulprizio, Melissa Payer; Pawson, S.; Jacob, Daniel James (Copernicus GmbH, 2014)The GEOS-Chem global chemical transport model (CTM), used by a large atmospheric chemistry research community, has been re-engineered to also serve as an atmospheric chemistry module for Earth System Models (ESMs). This ... -
Present and future nitrogen deposition to national parks in the United States: critical load exceedances
Ellis, R. A.; Jacob, Daniel James; Sulprizio, Melissa Payer; Zhang, L.; Holmes, C. D.; Schichtel, B. A.; Blett, T.; Porter, E.; Pardo, L. H.; Lynch, J. A. (Copernicus GmbH, 2013)National parks in the United States are protected areas wherein the natural habitat is to be conserved for future generations. Deposition of anthropogenic nitrogen (N) transported from areas of human activity (fuel combustion, ... -
Spatially resolving methane emissions in California: constraints from the CalNex aircraft campaign and from present (GOSAT, TES) and future (TROPOMI, geostationary) satellite observations
Wecht, Kevin James; Jacob, Daniel James; Sulprizio, Melissa Payer; Santoni, G; Wofsy, Steven Charles; Parker, R.; Bösch, H.; Worden, J. (Copernicus GmbH, 2014)We apply a continental-scale inverse modeling system for North America based on the GEOS-Chem model to optimize California methane emissions at 1/2° × 2/3° horizontal resolution using atmospheric observations from the ...
