SUVIM stations in Belgium until 2016

Between 1993 and 2016, BIRA-IASB maintained 6 stations in Belgium for the monitoring of the ground-based solar irradiance, mainly in the UV spectral range. A collaboration was also established with the Grand Duchy of Luxembourg (station at Diekirch). Measurements were also performed at the Princess Elisabeth Antarctica (PEA) Research Station. Radiometric measurements of solar irradiance: mainly performed using spectroradiometer, filter radiometers and pyranometers. Anscillary measurements: cloud coverage, sunshine duration, sky imager and atmospheric parameters (using meteorological instruments). Following highest level of quality assurance and for traceability reasons, the proposed data from this network are currently limited to those obtained with multi-channel filter radiometers (GUV-2511) manufactured by [BIOSPHERICAL Inc](https://www.biospherical.com/) for the time period 2011-2015.
