TL;DR: In this article, the authors report the results of grab samples made in the Arctic winter atmosphere, which were analyzed for the presence of nonmethane hydrocarbons (C{sub 2} - C{sub 6}).

TL;DR: The concept of ozone production efficiency (OPE) per unit NOx is based on photochemical models and provides a tool with which to assess potential regional tropospheric ozone control strategies involving NOx emissions reductions.

TL;DR: In this article, the authors measured the mixing ratios and total reactivity of HO2 and OH during the mid-summer 1999 SOS campaign in Nashville, Tennessee, and found that HO2 was greater than expected during daytime when NO mixing ratios were high; ozone production did not decrease as expected when NO was higher than 2 ppbv.

TL;DR: A wide array of volatile organic compound (VOC) measurements was conducted in the Valley of Mexico during the MCMA-2002 and 2003 field campaigns as discussed by the authors, where four distinct analytical techniques were used: whole air canister samples with Gas Chromatography/Flame Ionization Detection (GC-FID), on-line chemical ionization using a Proton Transfer Reaction Mass Spectrometer (PTR-MS), continuous real-time detection of olefins using a Fast Olefin Sensor (FOS), and long path measurements using UV Differential Optical Absorption Spect

TL;DR: A weekly air sampling program at Fraserdale, Ontario (latitude 50° N, longitude 82° W) has revealed distinct seasonal trends in the isoprene, alkane, and acetylene concentrations over the period April 1990 to October 1992 as mentioned in this paper.
