We are proud to announce the acceptance and publication of the final version of our latest manuscript in the open access journal Atmospheric Chemistry and Physics. In this paper we present a new parameterization of the reactive uptake of glyoxal and methylglyoxal by atmospheric aerosols and cloud droplets. Our calculations take into account newly available information regarding the gas-particle partitioning of these species and their chemical processing in the aerosol phase. The particle and droplet types considered were based on definitions in GEOS-Chem v11, but the approach is general. We expect application of these parameterizations will result in improved representation of aqueous secondary organic aerosol formation in atmospheric chemistry models.
