Impact of halogen monoxide chemistry upon boundary layer OH and HO[subscript 2] concentrations at a coastal site
The impact of iodine oxide chemistry upon OH and HO[subscript 2] concentrations in the coastal marine boundary layer has been evaluated using data from the NAMBLEX (North Atlantic Marine Boundary Layer Experiment) campaign, conducted at Mace Head, Ireland during the summer of 2002. Observationally c...
