Fully coupled “online” chemistry within the WRF model
Georg Grell,Steven E. Peckham,Rainer Schmitz,Stuart A. McKeen,Gregory J. Frost,William C. Skamarock,Brian Eder +6 more
TL;DR: The WRF/Chem model is statistically better skilled in forecasting O3 than MM5/Chem, with no appreciable differences between models in terms of bias with the observations, and consistently exhibits better skill at forecasting the O3 precursors CO and NOy at all of the surface sites.

TL;DR: It is shown that human exposure to carbonaceous aerosols of fossil origin is transitioning away from transportation-related sources and toward VCPs, and the focus of efforts to mitigate ozone formation and toxic chemical burdens need to be adjusted.

TL;DR: It is found that ozone production occurs at lower NOx and much larger VOC concentrations than does its summertime urban counterpart, leading to carbonyl (oxygenated VOCs with a C = O moiety) photolysis as a dominant oxidant source.

Determination of urban volatile organic compound emission ratios and comparison with an emissions database

TL;DR: In this paper, the emission ratios of VOCs relative to CO and acetylene were calculated using a method in which the ratio of a VOC with acetylene is plotted versus the photochemical age.
Potential impact of iodine on tropospheric levels of ozone and other critical oxidants
Douglas D. Davis,James H. Crawford,Shaw Chen Liu,Stuart A. McKeen,Alan R. Bandy,Donald C. Thornton,F. S. Rowland,Donald R. Blake +7 more
TL;DR: In this article, the first ever observations of CH3I in the middle and upper free troposphere as recorded during the NASA Pacific Exploratory Mission in the western Pacific were used.
