Better measures of how global levels of OH vary from year to year will improve climate science. The hydroxyl radical (OH) is an oxidizing molecule that has a major impact on the distribution and concentrations of pollutants and greenhouse gases in Earth's atmosphere. It is the most common oxidant in the troposphere, the lowest portion of the atmosphere. Understanding OH variability is important to evaluating human impacts on the atmosphere and climate. Measuring global OH distribution and… 
Uncertainties in isoprene photochemistry and emissions: implications for the oxidative capacity of past and present atmospheres and for climate forcing agents
Abstract. Isoprene and its oxidation products are major players in the oxidative chemistry of the troposphere. Current understanding of the factors controlling biogenic isoprene emissions and of the
Aqueous production of oxygen atoms from hydroxyl radicals.
TLDR
Details of the reactions and interactions that can occur between two OH* in water are probed by utilizing Car-Parrinello molecular dynamics simulations and advanced visualization techniques and reveal that the hemibonded interaction plays key role in the behavior of OH*(aq).
Investigating Climate-Chemistry Interactions on Multiple Spatiotemporal Scales
Fine dust is a significant component of regional fine particulate matter (PM2.5) air pollution in the western U.S., especially during spring, and human-caused climate change could increase dust
Future changes in global warming potentials under representative concentration pathways
Global warming potentials (GWPs) are the metrics currently used to compare emissions of different greenhouse gases under the United Nations Framework Convention on Climate Change. Future changes in
Need to Estimate the Net Global Warming Potential of Nitrogenous Fertilizers
Besides N2O emission, other oxidized and reduced N compounds (NH3, NOx, NO3-) are also emitted from soils as result of use of N fertilizers which have shortand long-term, direct and indirect impacts
Mobility mechanism of hydroxyl radicals in aqueous solution via hydrogen transfer.
TLDR
In insights into the local hydration and electronic structure of the OH* in aqueous solution from Car-Parrinello molecular dynamics and the mechanism of H-transfer between OH* and a water molecule are reported, revealing a novel H- transfer mechanism of hydrated OH*, resembling that ofhydrated OH(-) and presenting hybrid characteristics of hydrogen-atom and electron-proton transfer processes, where local structural fluctuations play a pivotal role.
Quantifying impacts of nitrogen use in European agriculture on global warming potential
This paper summarizes current knowledge on the impacts of changes of nitrogen (Nr) use in agriculture on the global warming potential (GWP) by its impact on carbon dioxide (CO2), nitrous oxide (N2O)
Quantitative structure-reactivity relationships of hydroxyl radical rate constants for linear and cyclic volatile methylsiloxanes.
TLDR
To measure •OH reaction rate constants for 4 cyclic and 4 linear VMS based on a relative rate method using a newly designed atmospheric chamber and to establish structure-reactivity relationships for the kinetics, better empirical models were developed by simple and multiple linear regressions of the measured values.
Laser-Induced Fluorescence of Hydroxyl (OH) Radical in Cold Atmospheric Discharges
The application of laser-induced fluorescence (LIF) to measurement of absolute concentration of hydroxyl radicals in cold atmospheric discharges is described. Though only the case of OH is presented,

New Directions: Watching over tropospheric hydroxyl (OH)
Mean tropospheric hydroxyl radical (OH) abundance is often used as a measure of the oxidation capacity (or “self-cleansing”) of the atmosphere. The primary mechanism by which atmospheric pollutant
Evidence for variability of atmospheric hydroxyl radicals over the past quarter century
[1] The hydroxyl free radical (OH) is the major oxidizing chemical in the atmosphere, destroying about 3.7 petagrams (Pg) of trace gases each year, including many gases involved in ozone depletion,
Small Interannual Variability of Global Atmospheric Hydroxyl
TLDR
A small interannual OH variability is inferred, indicating that global OH is generally well buffered against perturbations and consistent with measurements of methane and other trace gases oxidized primarily by OH, as well as global photochemical model calculations.
Short-term variations in the oxidizing power of the atmosphere
TLDR
Records of carbon monoxide containing radiocarbon (14CO), which is oxidized by hydroxyl radicals, from clean-air sites at Baring Head, New Zealand, and Scott Base, Antarctica, spanning 13 years are shown.

Interannual variability and trend of CH4 lifetime as a measure for OH changes in the 1979–1993 time period
[1] The interannual variability and trend in the CH4 lifetime, as a measure for global mean OH concentration, have been analyzed systematically with three-dimensional (3-D) chemistry-transport model
