Greece

Monitoring in Greece is being conducted by three organizations: Aristotle University of Thessaloniki, the University of Athens, and the Foundation for Biomedical Research of the Academy of Athens.
The scientists at the University of Thessaloniki in Greece have pioneered instrument intercomparisons with UV instruments. In addition to extensive monitoring in Greece, Aristotle University operates 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 Ispra, Italy in May 1995. All UV-measurements carried out by the University are part of the GR-UVNET in Greece. Data from LAP-AUTH is submitted to both the European UV Database (EUVDB) and European Database for UV Climatology and Evaluation (EDUCE).
Please contact Alkiviadis Bais for more information on UV monitoring at Thessaloniki.

Varotsos Costas at the University of Athens is responsible for the operation of one spectal radiometer in the city of Athens.

Christos Zerefos, with the Foundation for Biomedical Research of the Academy of Athens, operates two instruments at the Academy in Athens. Both instruments contribute to the Greeek National Network for UV-Monitoring (UV-NET). Data has been submitted to the World Ozone and UV Radiation Data Centre (WOUDC). Both instruments undergo regular calibration.

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.
