| Zusammenfassung |
| This paper summarizes an evaluation of model simulations with a regional
scale atmospheric climate-chemistry/aerosol model called REMOTE, which has
been extended by a microphysical aerosol module. Model results over Europe
are presented and compared with available measurements in surface air
focusing on the European distribution and variability of primary and
secondary aerosols. Additionally, model results obtained with detailed
aerosol microphysics are compared to those based on an aerosol bulk mass
approach revealing the impact of dry deposition fluxes on atmospheric burden
concentration. An improved determination of elevated ozone and sulfate
concentrations could be achieved by considering a diurnal cycle in the
anthropogenic emission fluxes. Deviation between modelled and measured
organic carbon concentrations can be mainly explained by missing formation
of secondary organic aerosols and deficiencies in emission data. Changing
residential heating practices in Europe, where the use of wood is no longer
restricted to rural areas, need to be considered in emission inventories as
well as vegetation fire emissions which present a dominant source of organic
carbon. |
