Journal ArticleDOI
Why do models overestimate surface ozone in the Southeast United States
Katherine R. Travis,Daniel J. Jacob,Jenny A. Fisher,Patrick S. Kim,Eloise A. Marais,Lei Zhu,Karen Yu,C. Chan Miller,Robert M. Yantosca,Melissa P. Sulprizio,Anne M. Thompson,Paul O. Wennberg,John D. Crounse,Jason M. St. Clair,Ronald C. Cohen,Joshua L. Laughner,Jack E. Dibb,Samuel R. Hall,Kirk Ullmann,Glenn M. Wolfe,Glenn M. Wolfe,I. B. Pollack,Jeff Peischl,Jeff Peischl,J. A. Neuman,J. A. Neuman,Xianliang Zhou,Xianliang Zhou +27 more
TL;DR: The authors used detailed chemical observations from the SEAC4RS aircraft campaign in August and September 2013, interpreted with the GEOS-Chem chemical transport model at 0.3125° horizontal resolution, to understand the factors controlling surface ozone in the Southeast US.
Journal ArticleDOI
Direct observation of changing NO x lifetime in North American cities.
TL;DR: Satellite observations of NO2 from a new high-resolution product are used to show that NOx lifetime in approximately 30 North American cities has changed between 2005 and 2014 in a manner consistent with the understanding of NOx chemistry.
Journal ArticleDOI
Using satellite observations of tropospheric NO 2 columns to infer long-term trends in US NO x emissions: the importance of accounting for the free tropospheric NO 2 background
Rachel F. Silvern,Daniel J. Jacob,Loretta J. Mickley,Melissa P. Sulprizio,Katherine R. Travis,Eloise A. Marais,Ronald C. Cohen,Joshua L. Laughner,Sungyeon Choi,Joanna Joiner,Lok N. Lamsal,Lok N. Lamsal +11 more
TL;DR: In this article, the authors show that the decrease in NO2 emissions reported by the US Environmental Protection Agency (EPA) is in fact largely consistent with observed network trends of surface NO2 and nano-ozone concentrations.
Journal ArticleDOI

Osterman,Ryan Pavlick,Coleen M. Roehl,Robert Schneider,Gary D. Spiers,Cathy To,Christopher Wells,Paul O. Wennberg,Amruta Yelamanchili,Shanshan Yu +32 more
TL;DR: The first public release of the OCO-3 Level 2 (L2) data products, called vEarly, is being distributed by NASA's Goddard Earth Sciences Data and Information Services Center (GES DISC).
Journal ArticleDOI
Lightning NOx Emissions: Reconciling Measured and Modeled Estimates With Updated NOx Chemistry
Benjamin A. Nault,Benjamin A. Nault,Joshua L. Laughner,Paul J. Wooldridge,John D. Crounse,Jack E. Dibb,G. Diskin,Jeff Peischl,Jeff Peischl,James R. Podolske,I. B. Pollack,I. B. Pollack,I. B. Pollack,T. B. Ryerson,Eric Scheuer,Paul O. Wennberg,Ronald C. Cohen +16 more
TL;DR: In this article, the authors combine upper tropospheric in situ observations from the Deep Convective Clouds and Chemistry (DC3) experiment and global satellite-retrieved NO 2 column densities to constrain mean lightning NO 2 emissions per flash.
