      abstract     = {We use the ECHAM5-HAMMOZ aerosol-chemistry-climate model to
                      quantify the influence of trace gas-aerosol interactions on
                      the regional and global distributions and optical properties
                      of aerosols for present-day conditions. The model includes
                      fully interactive simulations of gas phase and aerosol
                      chemistry including a comprehensive set of heterogeneous
                      reactions. We find that as a whole, the heterogeneous
                      reactions have only a small effect on the SO2 and sulfate
                      burden because of competing effects. The uptake of SO2 on
                      dust and sea salt decreases the SO2 concentrations while the
                      decrease in OH (that results from the uptake of HO2, N2O5,
                      and O-3) tends to increase SO2 (because of reduced
                      oxidation). The sulfate formed in sea salt aerosols from SO2
                      uptake accounts for 3.7 Tg(S) a(-1) $(5\%)$ of the total
                      sulfate production. Uptake and subsequent reaction of SO2 on
                      mineral dust contributes to a small formation of sulfate
                      (0.55 Tg(S) a(-1), $<1\%),$ but is responsible for the
                      coating of mineral dust particles, resulting in an extra 300
                      Tg a(-1) of dust being transferred from the insoluble to the
                      soluble mixed modes. The burden of dust in the insoluble
                      modes is reduced by $44\%,$ while the total burden is
                      reduced by $5\%$ as a result of enhanced wet deposition
                      efficiency. Changes in the sulfur cycle affect the H2SO4
                      concentrations and the condensation of H2SO4 on black
                      carbon. Accounting for heterogeneous reactions enhances the
                      global mean burden of hydrophobic black carbon particles by
                      $4\%.$ The changes in aerosol mixing state result only in a
                      small change in the global and annual aerosol optical depth
                      (AOD) and absorption optical depth (ABS), but have
                      significant implications on regional and seasonal scale. For
                      example, in the main polluted regions of the Northern
                      Hemisphere, AOD and ABS increase by $10-30\%$ and up to
                      $15\%,$ respectively, in winter.},
