Peroxyacetic acid rural atmosphere PAN-NOx cycle radical chemistry
2010/2/1
Peroxyacetic acid (PAA) is one of the most important atmospheric organic peroxides, which have received increasing attention for their potential contribution to the oxidation capacity of the troposphe...
Constraining the concentration of the hydroxyl radical in a stratocumulus-topped marine boundary layer from sea-to-air eddy covariance flux measurements of dimethylsulfide
hydroxyl radical stratocumulus-topped marine boundary layer sea-to-air eddy covariance flux measurements
2009/12/31
The hydroxyl radical (OH) is an important oxidant in the troposphere due to its high reactivity and relative abundance. Measuring the concentration of OH in situ, however, is technically challenging. ...
