abstract = {The impact of six heterogeneous gas-aerosol uptake
reactions on tropospheric ozone and nitrogen species was
studied using two chemical transport models, EMEP MSC-W and
ECHAM-HAMMOZ. Species undergoing heterogeneous reactions in
both models include N2O5, NO3, NO2, O3, HNO3 and HO2. Since
heterogeneous reactions take place at the aerosol surface
area, the modeled surface area density Sa of both models was
compared to a satellite product retrieving the surface area.
This comparison shows a good agreement in global pattern and
especially the capability of both models to capture the
extreme aerosol loadings in East Asia.The impact of the
heterogeneous reactions was evaluated by the simulation of a
reference run containing all heterogeneous reactions and
several sensitivity runs. One reaction was turned off in
each sensitivity run to compare it with the reference run.
The analysis of the sensitivity runs confirms that the
globally most important heterogeneous reaction is the one of
N2O5. Nevertheless, NO2, HNO3 and HO2 heterogeneous reaction
gain relevance particularly in East Asia due to the presence
of high NOx concentrations and high Sa in the same region,
although ECHAM-HAMMOZ showed much stronger responses than
EMEP in this respect. The heterogeneous reaction of O3
itself on dust is of minor relevance compared to the other
heterogeneous reactions. The impacts of the N2O5 reactions
show strong seasonal variations, with biggest impacts on O3
in spring time when photochemical reactions are active and
N2O5 levels still high. Evaluation of the models with
northern hemispheric ozone surface observations yields a
better agreement of the models with observations in terms of
concentration levels, variability, and temporal correlations
at most sites when the heterogeneous reactions are
incorporated.},
