The abundance of the highly reactive hydroxyl radical is well buffered against perturbations. The oxidizing capacity of the global atmosphere is largely determined by hydroxyl (OH) radicals and is diagnosed by analyzing methyl chloroform (CH3CCl3) measurements. Previously, large year-to-year changes in global mean OH concentrations have been inferred from such measurements, suggesting that the atmospheric oxidizing capacity is sensitive to perturbations by widespread air pollution and natural… 

Topics from this paper

Modulation of hydroxyl variability by ENSO in the absence of external forcing
It is found that natural OH variability can produce (unforced) methane trends as large as the observed changes in methane over the last few decades and that ENSO is the dominant mode of OH variability, with the modulation of OH occurring primarily through lightning NOx.
Large uncertainties in global hydroxyl projections tied to fate of reactive nitrogen and carbon
It is demonstrated that intermodel differences in OH are best explained by disparate implementations of chemical and physical processes that affect reactive oxides of nitrogen and organic chemical species, and implies a need for additional observational constraints on NOy partitioning and lifetime, especially in the remote free troposphere.
Global tropospheric hydroxyl distribution, budget and reactivity
Abstract. The self-cleaning or oxidation capacity of the atmosphere is principally controlled by hydroxyl (OH) radicals in the troposphere. Hydroxyl has primary (P) and secondary (S) sources, the
Mapping hydroxyl variability throughout the global remote troposphere via synthesis of airborne and satellite formaldehyde observations
This work combines the robust chemical relationship between OH and formaldehyde (HCHO) with satellite-based HCHO observations to infer total-column OH throughout the remote troposphere, and offers unique insights on near-global oxidizing capacity.
Observational evidence for interhemispheric hydroxyl-radical parity
The findings suggest that top-down emission estimates of reactive species such as nitrogen oxides in key emitting countries in the NH that are based on a NH/SH OH ratio larger than 1 may be overestimated.
Getting a Better Estimate of an Atmospheric Radical
An indirect method is used to present a global estimate of OH's interannual variability that is consistent with past model-based estimates, which could be an important step toward understanding OH's role in the atmosphere, including its role in influencing concentrations of methane (CH4), a gas important in considerations of global warming.
Paleo-Perspectives on Potential Future Changes in the Oxidative Capacity of the Atmosphere Due to Climate Change and Anthropogenic Emissions
The oxidizing capacity of the atmosphere, defined as the global mean tropospheric abundance of the hydroxyl radical (OH·), strongly influences air pollution by controlling the lifetimes of gaseous
An Observationally Constrained Evaluation of the Oxidative Capacity in the Tropical Western Pacific Troposphere
Hydroxyl radical (OH) is the main daytime oxidant in the troposphere and determines the atmospheric lifetimes of many compounds. We use aircraft measurements of O3, H2O, NO, and other species from
Trends in global tropospheric hydroxyl radical and methane lifetime since 1850 from AerChemMIP
Abstract. We analyse historical (1850–2014) atmospheric hydroxyl (OH) and methane lifetime data from CMIP6/AerChemMIP simulations. Global OH changed little from 1850 up to around 1980, then increased
Deriving global OH abundance and atmospheric lifetimes for long-lived gases: a search for CH3CCl3 alternatives
An accurate estimate of global hydroxyl radical (OH) abundance is important for projections of air quality, climate, and stratospheric ozone recovery. As the atmospheric mixing ratios of methyl


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
On the role of hydroxyl radicals in the self-cleansing capacity of the troposphere
Thousands of megatons natural and anthropogenic gases are released and subsequently removed from the troposphere each year. Photochemical reactions, initiated by hydroxyl (OH) radicals, oxidise most
Interhemispheric asymmetry in OH abundance inferred from measurements of atmospheric 14CO
THE hydroxyl radical, OH, is the chief oxidizing agent in the atmosphere, and is responsible for removing many natural and anthropogenic trace gases1. At present, OH cannot be measured directly with
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,
Short-term variations in the oxidizing power of the atmosphere
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.
New observational constraints for atmospheric hydroxyl on global and hemispheric scales
These results set firm upper limits on the global and Southern Hemispheric lifetimes of methyl chloroform and confirm the predominance of hydroxyl in the tropics.
