Proton-transfer-reaction mass spectrometry (PTR-MS) has been widely used to study the
emissions, distributions, and chemical evolution of volatile organic compounds (VOCs) in …

Proton‐transfer‐reaction mass spectrometry (PTR‐MS) allows real‐time measurements of
volatile organic compounds (VOCs) in air with a high sensitivity and a fast time response …

We evaluate the performance of a new chemical ionization source called Vocus, consisting
of a discharge reagent-ion source and focusing ion–molecule reactor (FIMR) for use in …

A fully coupled “online” Weather Research and Forecasting/Chemistry (WRF/Chem) model
has been developed. The air quality component of the model is fully consistent with the …

We present emission measurements of volatile organic compounds (VOCs) for western US
wildland fires made on the NSF/NCAR C‐130 research aircraft during the Western Wildfire …

Abstract The United States is now experiencing the most rapid expansion in oil and gas
production in four decades, owing in large part to implementation of new extraction …

Proton-transfer reaction mass spectrometry (PTR-MS) is a technique developed almost
exclusively for the detection of gaseous organic compounds in air. Volatile organic …

Proton-transfer-reaction mass spectrometry (PTR-MS) developed about 10 years ago is
used today in a wide range of scientific and technical fields allowing real-time on-line …

An extensive set of volatile organic compounds (VOCs) and particulate organic matter
(POM) was measured in polluted air during the New England Air Quality Study in 2002 …

Volatile organic compounds (VOCs) were measured online at an urban site in Bei**g in
August–September 2010. Diurnal variations of various VOC species indicate that VOCs …
