Monitoring in Greece is being conducted by two organizations in Greece: Aristotle University of Thessaloniki and the University of Athens. The scientists of the University of Thessaloniki in Greece have pioneered instrument intercomparisons of UV instruments. In addition to extensive monitoring in Greece, Aristotle University operates both a Brewer and a Yankee in Reykjavik. They have also established close collaboration and issue annual UV-B bulletins with Iceland, Poland and Hungarian UV-B networks. Aristotle University also participated in an instrument intercomparison in the Ispra, Italy in May 1995.
All measurements are global irradiance, with additional measurements of direct irradiance taken 5-9 times per day in Thessaloniki. There is also a LIDAR system for tropospheric aerosol measurements and an ozone soundings program at Thessaloniki. Turbidity measurements and cloud cover observations are available. A dark room with lamp calibration facilities is installed at LAP AUTH since 1994. Albedo measurements include columnar total ozone and SO2 amounts, long-path Differential Optical Absorption Spectrometers (DOAS), and a Canterbury Filter Photometer. Air pollution monitoring station and automatic two meteorological station (with speed, direction, temperature, and humidity). Other ancillary measurements of total global irradiance are made with the use of Kipp & Zonnen AC21 pyranometers at the stations of Thessaloniki, Kos, and Aktion.
