Criegee intermediates found to have big impact on troposphere

Scientists report direct measurements of reactions of a gas-phase Criegee intermediate using photoionization mass spectrometry. They found that oxidation of SO2 by Criegee intermediate is much faster than modelers assumed, so Criegee reactions may be a major tropospheric sulfate source, changing predictions of tropospheric aerosol formation.
