Abstract

The gas-phase concentrations were always less than 2.4 ppbv and generally less than 1 ppbv. Vertical profiles of H2O2 in the clear air around clouds and storm systems were highly variable. The concentrations of H2O2 in the cloud water ranged from the detection limit of 0.3μM to 112μM, with the higher values generally occurring in the vicinity of lightning activity. Hydrogen peroxide concentrations in cloud water were well below those calculated to be in Henry's law equilibrium with the gas-phase concentrations of H2O2 in the cloudy air. This is attributed to the rapid depletion of aqueous-phase H2O2 as it oxidizes S(IV). -from Authors
