| Zusammenfassung |
| A month (4 May to 8 June 2008) of ambient aerosol, air ion and gas phase
sampling (Finokalia Aerosol Measurement Experiment 2008, FAME-08) was
conducted at Finokalia, on the island of Crete, Greece. The purpose of the
study was to characterize the physical and chemical properties of aged
aerosol and to investigate new particle formation. Measurements included
aerosol and air ion size distributions, size-resolved chemical composition,
organic aerosol thermal volatility, water uptake and particle optical
properties (light scattering and absorption). Statistical analysis of the
aerosol mass concentration variations revealed the absence of diurnal
patterns suggesting the lack of strong local sources. Sulfates accounted for
approximately half of the particulate matter less than 1 micrometer in
diameter (PM1) and organics for 28%. The PM1 organic aerosol
fraction was highly oxidized with 80% water soluble. The supermicrometer
particles were dominated by crustal components (50%), sea salt (24%)
and nitrates (16%). The organic carbon to elemental carbon (OC/EC) ratio
correlated with ozone measurements but with a one-day lag. The average OC/EC
ratio for the study period was equal to 5.4. For three days air masses from
North Africa resulted in a 6-fold increase of particulate matter less than
10 micrometers in diameter (PM10) and a decrease of the OC/EC ratio by
a factor of 2. Back trajectory analysis, based on FLEXPART footprint plots,
identified five source regions (Athens, Greece, Africa, other continental
and marine), each of which influenced the PM1 aerosol composition and
properties. Marine air masses had the lowest PM1 concentrations and air
masses from the Balkans, Turkey and Eastern Europe the highest. |
