Hourly values of hydrological data in the area of Antikythira strait, produced by a marine mooring deployed by HCMR. The monitoring instruments have been positioned at two depths: a) Close to the bottom (approximately 895 m) and b) At intermediate depth (325 m). The mooring site is found at latitude 35ο 36.8 N and longitude 23o 32.3 E.

The files include daily observations of total ozone (DU), AOT at 1020 nm, water column (at 936 nm) and solar irradiance at 305 nm, 312 nm, 320 nm, 936 nm and 1020 nm (W/m2). Observations were made with the spectrophotometer MICROTOPS II by the Climate Research Group, Section of Environmental Physics and Meteorology, Faculty of Physics, National and Kapodistrian University of Athens. Validation of the data is needed for their proper use.

The data concern ozone measurements carried out at the Akrotiri station located at the Technical University of Crete. Measurements represent hourly ozone concentrations (ppb) from July 2020.

The dataset can be used to assess the spatial distribution of vulnerability of the urban fabric to floods based on individual specific characteristics that are statistically associated with vulnerability including underground garage ramps (UGR), light wells (LW), the construction material (MATERIAL), the presence of pilotis (PLT), the number of adjoining buildings on the side of each building (ADJ). The above are part of the geodatabase (attribute table) that accompanies the shapefile. The projection is Hellenic Geodetic Reference System 1987. In specif...

The file is a collection of paleo-proxies from the NE Mediterranean. The data are exclusively from cores from deep sea basins (ODP cores) and geological sections in Cyprus and relate to targeted periods of geological time: 1. Pliocene Warm Period (PWP): the high CO2 paleo-analogue of the "warm Pliocene" (5.3-3.0 million years) 2. Miocene Climatic Optimum (MCO): the Miocene Climate Optimum (14.7-17 million years). The file contains different sheets based on the study period (Miocene or Pliocene) and the code/name of each ODP core or geological section...

Mapping of the urban areas of Athens, Larissa and Rethymno into Local Climate Zones (LCZ). Data are available as raster images at a 100 m resolution. The LCZ classification system [(Stewart & Oke, 2012)](https://journals.ametsoc.org/view/journals/bams/93/12/bams-d-11-00019.1.xml) divides cities into discrete zones with specific urban form and function characteristics. Using remote sensing data, digital elevation models from the Hellenic Cadastre, and GIS data, we first derived urban morphological parameters, including the building height, the vegetation...

Time series of warm spell events using climate indices (1961-2021) for the cities of Athens and Larissa. Data include the first and the last day of each warm spell, and aggregate statistics about its intensity. Warm spell days were detected using the climate indices CTX90pct and CTX95pct. According to the climate index CTX90pct [(Perkins & Alexander 2013)](https://doi.org/10.1175/JCLI-D-12-00383.1), a warm spell event occurs when the maximum temperature exceeds for at least 3 consecutive days its 90th percentile for the base period. The 90th percentile ...

Time series with in-situ data of the Poseidon system for the monitoring of the Greek Seas. Data include atmospheric (such as air temperature, wind speed and direction, waves, currents) and marine physical and biochemical parameters (such as temperature, salinity, chlorophyll-a, dissolved oxygen, turbidity). Data have been collected by several measuring platforms like fixed buoys, Argo floats, oceanographic cruises, FerryBox systems. They have been subject to delayed mode quality control and expand from 25/5/2000-27/5/2020.

The data series consists of meteorological variables form 54 meteorological stations for the period 2010-2019. You can see the data visualization on https://www.meteo.gr/climate/ The parameters are ambient air temperature (°C), relative humidity (%), atmospheric pressure (hPa), rainfall (mm), wind speed (km/h) and direction. The observations stem from the automatic weather stations network of the National Observatory of Athens/meteo.gr. Information for the stations and possible malfunctions can be found on http://meteosearch.meteo.gr/ on the corre...

The data were produced by the nationwide phone survey carried out by the National Centre for Social Research (EKKE) during November-December 2020. The survey was conducted on a representative sample of the Greek population aged 18-65 years old , using structured questionnaire. It was aimed at identifying the views and attitudes of the Greek citizens regarding the climate change and its impacts. 1201 phone interviews were conducted with Greek residents. The response rate was 24,5%. Open-access data will be available until December 2022.
