Also, other factors effect
hydroxyl concentrations: NOx emissions, for example.
If this is correct, then we could be seeing be a very limited negative feedback from global warming just now which increases
hydroxyl concentrations which in turn breaks down the methane faster.
Tracking decadal trends in both methane and hydroxyl, Frankenberg and his colleagues noted that fluctuations in
hydroxyl concentrations correlated strongly with fluctuations in methane.
Not exact matches
Lower
concentration of hydrogen ions and negatively charged
hydroxyl ions helps increase energy, mental clarity, and overall alertness.
Hydroxyl radicals are important because of their role in breaking down many pollutants, although in large
concentrations, they also contribute to the formation of smog.
«Detergent» molecules may be driving fluctuations in atmospheric methane
concentrations: New study suggests
hydroxyl radicals may be behind unexplained recent increase in methane levels.»
If global levels of
hydroxyl decrease, global methane
concentrations will increase — even if methane emissions remain constant, the researchers say.
Redder regions in this simulation of a typical March
hydroxyl distribution contain higher
concentrations of the molecule.
That's the conclusion of two independent studies that indirectly tracked
concentrations of
hydroxyl, a highly reactive chemical that rips methane molecules apart.
This differs from gases like methane which do have a «real» lifetime due to reactions with
hydroxyl radicals, where for any given steady state anthropogenic methane emissions are, a stabilized
concentration value will eventually be reached.
Additional output from the ACCMIP runs will include
concentration / mass of radiatively active species, aerosol optical properties, and radiative forcings (clear and all sky) as well as important parameters that do not directly influence climate such as
hydroxyl, chemical reaction rates, deposition rates, emission rates, surface pollutants and diagnostics of tracer transport.
Model simulation of the
hydroxyl radical
concentration in the atmosphere.
First, the main chemical that reacts with methane in the atmosphere is the
hydroxyl radical (OH), thus more methane means that the
concentration of OH goes down.
