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 ...

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.
