| Particulate matter and photo-oxidant processes in the Eastern Mediterranean
have been studied using the UAM-AERO mesoscale air quality model in
conjunction with the NILU-CTM regional model. Meteorological data were
obtained from the RAMS prognostic meteorological model. The modeling domain
includes the eastern Mediterranean area between the Greek mainland and the
island of Crete. The modeling system is applied to study the atmospheric
processes in three periods, i.e. 13–16 July 2000, 26–30 July 2000 and 7–14
January 2001. The spatial and temporal distributions of both gaseous and
particulate matter pollutants have been extensively studied together with
the identification of major emission sources in the area. The modeling
results were compared with field data obtained in the same period. The
objective of the current modeling work was mainly to apply the UAM-AERO
mesoscale model in the eastern Mediterranean in order to assess the
performed field campaigns and determine that the applied mesoscale model is
fit for this purpose. Comparison of the modeling results with measured data
was performed for a number of gaseous and aerosol species. The UAM-AERO
model underestimates the PM10 measured concentrations during summer and
winter campaigns. Discrepancies between modeled and measured data are
attributed to unresolved particulate matter emissions. Particulate matter in
the area is mainly composed by sulphate, sea salt and crustal materials, and
with significant amounts of nitrate, ammonium and organics. During winter
the particulate matter and oxidant concentrations were lower than the summer
values. |
