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 understanding of oxidation in forest atmospheres is being challenged by measurements
of unexpectedly large amounts of hydroxyl (OH). A significant number of these OH …

Most pollutants in the Earth's atmosphere are removed by oxidation with highly reactive
hydroxyl radicals. Field measurements have revealed much higher concentrations of …

Peroxy radicals formed by addition of OH and O2 to the olefinic carbon atoms in
methacrolein react with NO to form methacrolein hydroxy nitrate and hydroxyacetone. We …

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 …

Measurements of hydroxyl (OH) and hydroperoxy (HO2*) radical concentrations were made
at the Pasadena ground site during the CalNex‐LA 2010 campaign using the laser‐induced …

A consistent body of experimental evidence from work of other groups is presented in
support of the novel, theoretically based, isoprene oxidation mechanism we recently …

Triggered by recent developments from laboratory and field studies regarding major NO x
sink pathways in the troposphere, this study evaluates the influence of chemical …

Theoretical, laboratory, and chamber studies have shown fast regeneration of the hydroxyl
radical (OH) in the photochemistry of isoprene, largely due to unimolecular reactions which …

HO 2 concentration measurements are widely accomplished by chemical conversion of HO
2 to OH including reaction with NO and subsequent detection of OH by laser-induced …
