Sources of Atmospheric Aerosols in Heraklion, Crete During Winter Time
Abstract
The contribution of Black Carbon (BC) to the levels of PM10 was studied in the city of Heraklion, Crete. Measurements were performed at the atmospheric quality measurement station of the Region of Crete at the Heraklion city center during the winter/spring period of 2014–2015 and 2015–2016. Continuous measurements were performed using a beta-attenuation PM10 monitor and a 7-wavelength Aethalometer with a time resolution of 30 and 5 min respectively. For direct comparison to background regional conditions, concurrent routine measurements at the atmospheric research station at Finokalia were utilized as background reference. Analysis of exceedances in the daily PM10 mass concentration (50 µg m−3) showed that the majority of the exceedances was related to long range transport of Saharan dust rather than local sources. However, compared to the Finokalia station it was found that there were 60 % more exceedances in Heraklion, the superimposition of transported pollutants on the local pollution was the reason for the additional exceedance days. Excluding dust events, it was found that the PM10 variability was dependent on the BC abundance, traffic during rush hours in the morning and biomass burning for domestic heating in the evening contributed significantly to PM10 levels in Heraklion.
