(Corresponding) Bougiatioti A., Dimitriou K., Ramonet M., Pierros F., Michalopoulos P., Liakakou E., Solomos S., Quehe P., Delmotte M., Gerasopoulos E., Kanadikou M., Mihalopoulos N.

Topic:

Climpact: national network for climate change and its impacts

Yearlong greenhouse gases (CO2 and CH4) concentration measurements were performed for the first time in the city of Athens, from 21/12/2018 to 31/12/2019, and analyzed in relation to atmospheric levels, wind direction at a local, regional and long-range transport scale. Clear diurnal and seasonal...Read more

Estimating Flood Risk at town scale: the case of the 2017 flash flood in Mandra, Greece.

(Corresponding) Bloutsos A., Diakakis M., Mitsopoulos G., Tsokanis K., Lekkas E., Baltas E., Stamou A.

Topic:

Climpact: national network for climate change and its impacts

Effective flood management requires the priori assessment of the flood event, its consequences, and thus its risk, which give insight into what situations we expect and allow us to evaluate possible measures, including the implementation of an Early Warning System. In the present work, we briefly...Read more

Flood modelling using a combined 1D/2D model: the case of the 2017 flash flood in Mandra, Greece

(Corresponding) Mitsopoulos G., Bloutsos A., Diakakis M., Panagiotatou E., Lekkas E., Baltas E., Stamou A.

Topic:

Climpact: national network for climate change and its impacts

The design of an efficient Early Warning System for floods in a specific region requires the knowledge of the hydrodynamic behavior of floods that affects flood arrival times and thus the available warning times. In the present work, we attempt to answer the following research question “Is a...Read more

Interannual large-scale variability in the Eastern Mediterranean Sea and interactions with the Aegean Sea

(Corresponding) Velaoras D.

Topic:

Climpact: national network for climate change and its impacts

The Mediterranean Sea and its eastern sub-basin are marginal oceanic basins subjected to strong anthropogenic and natural pressures. During the last decades new findings have revised the way of assessing the circulation and physical functioning of the eastern Mediterranean Sea. Natural oscillations...Read more

Methane distribution over Greece as derived from Sentinel-5P TROPOMI data

EVANGELOU I., GIALESAKIS N., DASKALAKIS N., (Corresponding) KANAKIDOU M.

Topic:

Climpact: national network for climate change and its impacts

Global warming, induced mainly by greenhouse gases emitted by human activities, is an environmental issue of crucial importance for society. Greenhouse gases, such as methane (CH4), need to be monitored and their anthropogenic emissions quantified in order to be reduced. We here present, the first...Read more

System-Dynamic models for groundwater management in SW Messinia, under different climatic scenarios

(Corresponding) Kastanidi E., Maneas G., Panagopoulos I., Viaene P., De Kok J., Berg H., Manzoni S., Velaoras D., Karageorgis A.

Topic:

Climpact: national network for climate change and its impacts

SW Messinia, Greece, is an interlinked coastal-inland area in the Eastern Mediterranean region. Extensive olive tree plantations and tourism are the main human activities in the area, both of which depend on groundwater resources to cover their irrigation and supply needs. The same groundwater...Read more

CO2 and NO2 distributions over Greece as seen by OCO-2 and TROPOMI

Gialesakis N., Daskalakis N., (Corresponding) Kanakidou M.

Topic:

Climpact: national network for climate change and its impacts

Greenhouse gases are the driving force behind human-induced global warming. Carbon dioxide (CO2) is the greenhouse gas (GHG) with the longer lifetime in the atmosphere, in the order of hundreds of years, and the largest contribution to the radiative forcing of the atmosphere due to its increasing...Read more

Influence of fires on atmospheric composition over Greece as seen by TROPOMI S5P

Kalogeraki E., Sfakianaki M., Gialesakis N., Chatziparaschos M., Daskalakis N., (Corresponding) Kanakidou M.

Topic:

Climpact: national network for climate change and its impacts

The present study uses data from the TROPOspheric Monitoring Instrument (TROPOMI) on board Copernicus Sentinel-5 Precursor satellite to investigate the impact of the forest fires plumes on atmospheric aerosols and gases. For this purpose, the Aerosol Index, nitrogen dioxide (NO2) and carbon...Read more

(Corresponding) Chantzi P., Papadimitriou E., Aidona E., Kantiranis N., Doani S., Vouvalidis K., Almpanakis K.

Topic:

Climpact: national network for climate change and its impacts

Sediment cores of 4m were sampled in Epanoni coastal lagoon basin in Eastern Thermaikos Gulf. Within this study, we present results of Magnetic Susceptibility (MS) measurements and sedimentological analysis (XRD and grain-size distribution) for the first meter EP1-1 aiming to contribute to the...Read more
