The expanding network of radiometric stations includes two stations within Attica region, the historic radiometric station in Thissio and the newest in Penteli, but also six more stations scattered throughout Greece: in Klokotos (Trikala), in Larissa (Thessaly), in Methoni (Messinia, South Peloponnese), in Filotas (Florina), in Andros island (Cyclades) and in Antikythira island. Also included is another high altitude station (at 2340 m) in Neraidorahi site of Helmos mountain in Kalavryta (Achaia).
At all of the above stations, the intensity of the total incoming solar radiation (in W/m2) incident at a horizontal plane is recorded, in five of them the diffuse solar component (in W/m2) is recorded in parallel, while in four of them the duration of sunshine duration (in minutes) is also measured.
Both radiometric stations at Thissio and Penteli sites also record the intensity of the incoming Ultra-Violet solar radiation (Total UV, UV-A, UV-B, in W/m2) as well as the intensity of the natural daylight (in Lux) (Total and Diffuse components).
Furthermore, all basic meteorological parameters such as air temperature (oC) and relative humidity (%), atmospheric pressure (hPa), wind speed (m/sec) and direction (degrees) and total precipitation (mm) (rainfall, snow, hail) are recorded in parallel.
Real-time measurements of the above actinometric and meteorological parameters are widely available to the public through the following WEB link: www.iersd.noa.gr/WeatherOnLine.
For each parameter presented, the historic daily fluctuation is also available throughout the WEB-page for a period of 10 days.
All actinometric and meteorological observations and measurements are automatically saved in the database for further statistical analysis.
