TL;DR: In this article, the authors determined enhancement ratios for NOx, PAN, and other NOy species from boreal biomass burning using aircraft data obtained during the ARCTAS-B campaign and examined the impact of these emissions on tropospheric ozone in the Arctic.
Journal ArticleDOI

TL;DR: In this paper, the authors used observations from the April 2008 NASA ARCTAS aircraft campaign to the North American Arctic, interpreted with a global 3D chemical transport model (GEOS-Chem), to better understand the sources and cycling of hydrogen oxide radicals (HOx≡H+OH+peroxy radicals) and their reservoirs (HOy≡HOx+peroxides) in the springtime Arctic atmosphere.
Journal ArticleDOI
Emissions of greenhouse gases from a North American megacity
TL;DR: In this article, the South Coast air basin (SCB), a densely populated urban region of Southern California, USA, which includes Los Angeles and the surrounding suburbs, was studied.
Journal ArticleDOI
Boreal forest fire emissions in fresh Canadian smoke plumes: C 1 -C 10 volatile organic compounds (VOCs), CO 2 , CO, NO 2 , NO, HCN and CH 3 CN
Isobel J. Simpson,S. K. Akagi,Barbara Barletta,Nicola J. Blake,Yonghoon Choi,Glenn S. Diskin,Alan Fried,Henry E. Fuelberg,Simone Meinardi,F. S. Rowland,Stephanie A. Vay,Andrew J. Weinheimer,Paul O. Wennberg,P. Wiebring,Armin Wisthaler,M. Yang,M. Yang,Robert J. Yokelson,Donald R. Blake +18 more
TL;DR: In this paper, the authors estimate that boreal forest fires release 2.4 ± 0.6 Tg C yr−1 in the form of NMVOCs, with approximately 41 % of the carbon released as C1-C2 NMVs and 21 % as pinenes.
Journal ArticleDOI
The photochemistry of acetone in the upper troposphere: A source of odd-hydrogen radicals
Stuart A. McKeen,Tomasz Gierczak,James B. Burkholder,Paul O. Wennberg,Thomas F. Hanisco,E. R. Keim,R. S. Gao,Shaw Chen Liu,A. R. Ravishankara,David W. Fahey +9 more
TL;DR: In this paper, the photodissociation quantum yields for acetone in the 290-320 nm wavelength region for pressures and temperatures characteristic of the upper troposphere were compared with those obtained during the NASA and NOAA sponsored Stratospheric Tracers of Atmospheric Transport (STRAT) field campaign.
