The hydroxyl radical, OH, initiates the removal of the majority of trace gases in the
atmosphere, and together with the closely coupled species, the hydroperoxy radical, HO2, is …

Online coupled mesoscale meteorology atmospheric chemistry models have undergone a
rapid evolution in recent years. Although mainly developed by the air quality modelling …

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 …

We implement a new isoprene oxidation mechanism in a global 3‐D chemical transport
model (GEOS‐Chem). Model results are evaluated with observations for ozone, isoprene …

We use 2005–2009 satellite observations of formaldehyde (HCHO) columns from the OMI
instrument to infer biogenic isoprene emissions at monthly 1× 1° resolution over the African …

The lifetime of methane is controlled to a very large extent by the abundance of the OH
radical. The tropics are a key region for methane removal, with oxidation in the lower tropical …

The first nitryl chloride (ClNO2) measurements in the UK were made during the summer
2012 ClearfLo campaign with a chemical ionization mass spectrometer, utilizing an I …

The Uintah Basin in northeastern Utah, a region of intense oil and gas extraction,
experienced ozone (O 3) concentrations above levels harmful to human health for multiple …

Tropical tropospheric ozone affects Earth's radiative forcing and the oxidative capacity of the
atmosphere. Considerable work has been devoted to the study of the processes controlling …

UV radiation is an essential driver for the formation of photochemical smog, which includes
ground-level ozone and particulate matter (PM). Recent analyses support earlier work …
