 Great Greek Success!!! The Greek GEO Office, which is operated by our group, initiated in cooperation with UNESCO, a global activity within GEO titled “Earth Observations for Climate Change Impacts on World Heritage Cities”. The Community Activity was approved last week from the GEO Programme Board and has been officially included in its Working Programme, incorporating several urban cultural heritage aspects. In this initiative, more than 80 partners have already joined, originating from 24 countries and 10 international organisations. Read our article for more details.

The new research of our group demonstrates the network of low-cost, compact, particulate matter (PM) sensors which operates in Athens, the largest city in Greece, for five months now, and how it performs with respect to measurement accuracy and other external factors.

Monoterpenes and isoprene are biogenic volatile organic compounds (BVOCs) contributing significantly to the formation of secondary organic aerosol (SOA) and tropospheric ozone (O3). Despite they are considered of biogenic origin, other emission sources might contribute to their levels in urban environments. Does it also stand for Athens? Read our article for more details.


APCG digs into the impacts of chemical weathering on Cultural Heritage (CH). Twenty-one archaeological sites in Greece were selected to study their exposure to particulate pollution, in terms of aerosol loading and chemical type, to infer on the potential impact on the structural materials (specifically stone) of the monuments, using Space-Borne Remote Sensing instruments, MODIS and CALIPSO.


In our new article the novel 3D-PSCF model was applied in Athens for the first time, providing new information regarding the vertical zones in which transport of pollutants occurs.

APCG meets on a monthly basis, to discuss on state-of-the-art research issues of interest to its members. Today, another fruitful meeting was held at IERSD premises, where Dr. Stelios Myriokefalitakis introduced the importance of multiphase processes on the formation of secondary organic aerosol (SOA) in the atmosphere and on atmospheric nutrient cycles. Also, his modeling results on the impacts of bioaerosols on the global scale set the basis for a long discussion on the health aspects of atmospheric pollution, as well as on the bridging spatial model scales.


APCG members have participated in the European Aerosol Conference – EAC 2019, 25-30 August 2019, Gothenburg, Sweden, with the following presentations:

1) Iasonas Stavroulas, Eleni Liakakou, Georgios Grivas, Nikolaos Mihalopoulos and Evangelos Gerasopoulos, Characterization of atmospheric pollution at the major Greek port city of Piraeus.

2) Despina Paraskevopoulou, Aikaterini Bougiatioti, Iasonas Stavroulas, Maria Tsagkaraki, Athanasios Nenes and Nikolaos Mihalopoulos, Wintertime oxidative potential and optical properties of brown carbon in atmospheric aerosol.

Members of the APCG research team have won and participate in the newly funded program ‘Support of new researchers – B cycle’ of the Ministry of Finance and Development. State-of-the-art research will be performed, dedicated to the study of atmospheric chemistry over the urban center of Athens using in situ, remote sensing and modeling EO platforms.

Δέκα μέλη του ερευνητικού δυναμικού της ομάδας APCG επιβραβεύθηκαν και θα συμμετέχουν σε 3 ερευνητικά προγράμματα που θα χρηματοδοτηθούν στο πλαίσιο της Πράξης:  «Υποστήριξη ερευνητών με έμφαση στους νέους ερευνητές – κύκλος Β’» (δημοσίευση εδώ). Θα πραγματοποιηθεί εκτενής έρευνα στο ευρύ αντικείμενο αιχμής της ατμοσφαιρικής χημείας στην περιοχή του λεκανοπεδίου της Αττικής, χρησιμοποιώντας εξειδικευμένες μετρήσεις τόσο από επιτόπιες παρατηρήσεις, όσο και με τις μεθόδους τηλεπισκόπησης και αριθμητικών προσομοιώσεων.

According to UNs “World Urbanization Prospects: 2014 Revision” in today’s increasingly global and interconnected world, over half of the world’s population lives in urban areas, while the coming decades will bring further profound changes to the size and spatial distribution of the global population, also due to increasing migration processes. The continuing urbanization is projected to add 2.5 billion of urban population by 2050, and the world population living in cities to increase to 66%. Under these circumstances, sustainable development challenges will increasingly concentrate in cities.
