      abstract     = {Heterogeneous uptake of hydroperoxyl radicals (HO2) onto
                      aerosols has been proposed to be a significant sink of HOx,
                      hence impacting the atmospheric oxidation capacity. Accurate
                      calculation of the HO2 uptake coefficient γHO2 is key to
                      quantifying the potential impact of this atmospheric
                      process. Laboratory studies show that γHO2 can vary by
                      orders of magnitude due to changes in aerosol properties,
                      especially aerosol soluble copper (Cu) concentration and
                      aerosol liquid water content (ALWC). In this study we
                      present a state-of-the-art model called MARK to simulate
                      both gas- and aerosol-phase chemistry for the uptake of HO2
                      onto Cu-doped aerosols. Moreover, a novel parameterization
                      of HO2 uptake was developed that considers changes in
                      relative humidity (RH) and condensed-phase Cu ion
                      concentrations and which is based on a model optimization
                      using previously published and new laboratory data included
                      in this work. This new parameterization will be applicable
                      to wet aerosols, and it will complement current IUPAC
                      recommendations.},
