Total averaged-dry air mole fractions of greenhouse gases for the region of Thessaloniki, such as carbon dioxide, methane, water vapor, carbon monoxide . Measurements were performed using a portable Bruker EM27/SUN spectrometer in the frame of the COllaborative Carbon Column Observing Network (COCCON), which measures direct solar radiation and each spectrum is obtained every 58 seconds, during clear-sky days. Data also include other measured quantities such as: the uncertainty of each measurement (rms), the time of measurement (UTC), the solar zenith ang...

The files include daily observations of mean, maximum and minimum air temperature, mean daily values of relative humidity and daily precipitation amount since 1901 in Athens. The data are derived from the historical climatic station of the National Observatory of Athens (the oldest climatic station of Greece). The station has been permanently established atT hissio, on the small Hill of Nymphs (latitude: 37.972 N, longitude: 23.717 E, altitude: 107 m above MSL) near the centre of Athens since the late 19th century, without relocations over the years. The ...

Collection of paleoclimate proxy data, to create spatio-temporal paleoclimate restoration fields, with the aim of understanding mechanisms of significant climate changes in the last 2,000 years. Nar Lake δ18O data (Jones et al. 2006) provide indirect information on the amount of precipitation through the precipitation-evaporation balance. The Ti (cps) record of Lake Neor (Sharifi et al. 2015) determines the aeolian input to the regional peatland of Lake Neor that increases during dry periods. The high-resolution Ti/Ca record of the stratified coastal lake ...

One of the objectives of Action 2.1 "Data from aquatic (marine and terrestrial) ecosystems related to climate change" was to propose a management protocol of harmful algal blooms (HABs) in order to protect public health from exposure to the risk of cyanotoxins. Cyanotoxins released into lake water by toxic cyanobacteria are a large group of compounds with diverse physicochemical properties, chemical structures and toxic effects (hepatotoxic, neurotoxic, dermatotoxic, cytotoxic). International organizations such as WHO, US EPA and the Global Water Research ...

In the framework of Action 2.1 "Data from aquatic (marine and terrestrial) ecosystems related to climate change", the Photo-Catalytic Processes and Environmental Chemistry group of the Institute of Nanoscience and Nanotechnology of the National Centre for Scientific Research "Demokritos", focused on the study of the history of harmful algal blooms in aquatic ecosystems of Greece. One of the effects of climate change is the more frequent occurrence of harmful algal blooms in surface waters, which are mainly favored by the global warming, the eutrophicatio...

Hourly ozone values in ppb from the Finokalia station since 1997 of the Laboratory of Environmental Chemical Processes (ECPL) of the Department of Chemistry of the University of Crete

Hourly values of meteorological data from the Finokalia station of the Laboratory of Environmental Chemical Processes (ECPL) of the Department of Chemistry of the University of Crete. The data contains wind speed in m/s, direction in o, temperature in oC, relative humidity in %, total solar radiation in w/m2, pressure in hPa and precipitation height in mm.

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.
