      abstract     = {The impact of six heterogeneous gas–aerosol up-take
                      reactions on tropospheric ozone and nitrogen specieswas
                      studied using two chemical transport models, the
                      Mete-orological Synthesizing Centre-West of the European
                      Moni-toring and Evaluation Programme (EMEP MSC-W) and
                      theEuropean Centre Hamburg general circulation model
                      com-bined with versions of the Hamburg Aerosol Model
                      andModel for Ozone and Related chemical Tracers
                      (ECHAM-HAMMOZ). Species undergoing heterogeneous reactions
                      inboth models include N2O5, NO3, NO2, O3, HNO3, and
                      HO2.Since heterogeneous reactions take place at the aerosol
                      sur-face area, the modelled surface area density (Sa) of
                      both mod-els was compared to a satellite product retrieving
                      the surfacearea. This comparison shows a good agreement in
                      global pat-tern and especially the capability of both models
                      to capturethe extreme aerosol loadings in east Asia.The
                      impact of the heterogeneous reactions was evaluatedby the
                      simulation of a reference run containing all hetero-geneous
                      reactions and several sensitivity runs. One reactionwas
                      turned off in each sensitivity run to compare it withthe
                      reference run. The analysis of the sensitivity runs
                      con-firms that the globally most important heterogeneous
                      reac-tion is the one of N2O5. Nevertheless, NO2, HNO3,
                      andHO2heterogeneous reactions gain relevance particularly
                      ineast Asia due to the presence of high NOxconcentrationsand
                      highSain the same region. The heterogeneous reactionof
                      O3itself on dust is of minor relevance compared to theother
                      heterogeneous reactions. The impacts of the N2O5re-actions
                      show strong seasonal variations, with the biggest im-pacts
                      on O3in springtime when photochemical reactions areactive
                      and N2O5levels still high. Evaluation of the modelswith
                      northern hemispheric ozone surface observations yieldsa
                      better agreement of the models with observations in termsof
                      concentration levels, variability, and temporal
                      correlationsat most sites when the heterogeneous reactions
                      are incorpo-rated. Our results are loosely consistent with
                      results from ear-lier studies, although the magnitude of
                      changes induced byN2O5reaction is at the low end of
                      estimates, which seems tofit a trend, whereby the more
