abstract = {The main objective of this work is the study of the impact
of windblown dust, sea-salt aerosol and biogenic emissions
on particle pollution levels in Europe. The Natural
Emissions MOdel (NEMO) and the modelling system consisted of
the Weather Research and Forecasting model (WRF) and the
Comprehensive Air Quality model with extensions (CAMx) were
applied in a 30 km horizontal resolution grid, which covered
Europe and the adjacent areas for the year 2009. Air quality
simulations were performed for different emission scenarios
in order to study the contribution of each natural emission
source individually and together to air quality levels in
Europe. The simulations reveal that the exclusion of
windblown dust emissions decreases the mean seasonal PM10
levels by more than 3.3 μg/m3 $(∼20\%)$ in the Eastern
Mediterranean during winter while an impact of 3 μg/m3 was
also found during summer. The results suggest that sea-salt
aerosol has a significant effect on PM levels and
composition. Eliminating sea-salt emissions reduces PM10
seasonal concentrations by around 10 μg/m3 in Mediterranean
Sea during summer while a decrease of up to 6 μg/m3 is
found in Atlantic Ocean during autumn. Sea-salt particles
also interact with the anthropogenic component and therefore
their absence in the atmosphere decreases significantly the
nitrates in aerosols where shipping activities are present.
The exclusion of biogenic emissions in the model runs leads
to a significant reduction of secondary organic aerosols of
more than $90\%$ while an increase in PM2.5 levels in
central Europe and Eastern Mediterranean is found due to
their interaction with anthropogenic component.},
