“…An overview of the instrumentation is given in Lazaridis et al (2006). Details describing the individual instruments and their operating parameters are described elsewhere (Smolík et al 2003;Eleftheriadis et al 2006;Bryant et al 2006); here, only the online instruments will be described in more detail with the focus on the SMPS measurements.…”

“…This finding is similar to that of Aaltonen et al (2006) at Pallas, a remote site in Northern Finland, where they showed that the scattering and backscattering coefficients have a clear seasonal variation while the backscattering ratio does not show a consistent seasonal pattern. Also, Bryant et al (2006) showed that the backscattering ratio obtained at Finokalia, a remote costal site on the Greek island of Crete, exhibited little variability between July 2000 and January 2001. The mean backscatter ratio values obtained in the present study are comparable to the value of 0.13±0.02 Mm −1 obtained by Andreae et al (2002) in Sde Boker (Israel), under continental pollution conditions.…”

Physical and optical properties of aerosols over an urban location in Spain: seasonal and diurnal variability

Abstract. Measurements of aerosol optical properties and aerosol number size distribution obtained during the period from December 2005 to November 2007 at Granada, an urban site in south-eastern Spain, are analyzed. Large variations of the measured variables have been found, and related to variations in emissions sources and meteorological conditions. High values of aerosol absorption and scattering coefficients are obtained during winter and low values are measured during summer. This seasonal pattern in the surface aerosol optical properties is opposite to the seasonal cycle showed by columnar aerosol optical depth. The differences in the seasonal features of the surface and column-integrated data are related to seasonal variations in the aerosol vertical distribution, aerosol sources and boundary layer height. In winter the number density of "fine" particles (0.5

“…The contribution of these light absorbing particles is particularly important during the summer period when most of air masses over the Eastern Mediterranean originate from the Balkans, Turkey and Central/Eastern Europe (Vrekoussis et al, 2005;Bryant et al, 2006). During this period, continental (anthropogenic) aerosols, mainly composed of sulfate and carbonaceous material, contribute for almost 2/3 of the Aerosol Optical Depth (AOD) over the Greek-Turkish coastal region (Barnaba and Gobbi, 2004).…”

Long-term measurements of carbonaceous aerosols in the Eastern Mediterranean: evidence of long-range transport of biomass burning

Abstract. Long-term (5-year) measurements of Elemental Carbon (EC) and Organic Carbon (OC) in bulk aerosols are presented here for the first time in the Mediterranean Basin (Crete Island). A multi-analytical approach (including thermal, optical, and thermo-optical techniques) was applied for these EC and OC measurements. Light absorbing dust aerosols were shown to poorly contribute (+12% on a yearly average) to light absorption coefficient (b abs ) measurements performed by an optical method (aethalometer). Long-range transport of agricultural waste burning from European countries surrounding the Black Sea was shown for each year during two periods (March-April and July-September). The contribution of biomass burning to the concentrations of EC and OC was shown to be rather small (20 and 14%, respectively, on a yearly basis), although this contribution could be much higher on a monthly basis and showed important seasonal and interannual variability. By removing the biomass burning influence, our data revealed an important seasonal variation of OC, with an increase by almost a factor of two for the spring months of May and June, whereas BC was found to be quite stable throughout the year. Preliminary measurements of Water Soluble Organic Carbon (WSOC) have shown that the monthly mean WSOC/OC ratio remains stable throughout the year (0.45±0.12), suggesting that the partitioning between water soluble and water insoluble organic matter is not significantly affected by biomass burning and secondary organic aerosol (SOA) formation. A chemical mass closure performed in the fine mode (Aerodynamic Diameter, A.D.<1.5µm) showed that the mass contribution of organic matter (POM) was found to be essentially invariable during the year (monthly average of 26±5%).
