A three-dimensional-model inversion of methyl chloroform to constrain the atmospheric oxidative capacity [PDF]
Atmospheric Chemistry and Physics, 2021 Variations in the atmospheric oxidative capacity, largely determined by variations in the hydroxyl radical (OH), form a key uncertainty in many greenhouse and other pollutant budgets, such as that of methane (CH4).

Ozone pollution around a coastal region of South China Sea: interaction between marine and continental air [PDF]
Atmospheric Chemistry and Physics, 2018 Marine atmosphere is usually considered to be a clean environment, but this study indicates that the near-coast waters of the South China Sea (SCS) suffer from even worse air quality than coastal cities.
