SUVIM stations in Belgium

Since 2022, the measurements of ground-based solar UV-VIS irradiance are performed at four sites in Belgium.
The CSV resource contains the locations.

List of the BIRA-IASB instruments available on the stations:

• Spectrometer - Only installed in Uccle/Ukkel:
  • Double monochromator for global solar spectral UV-VIS irradiance measurements
  • Spectral coverage: 280 nm to 500 nm. Time sampling: 15 minutes.
  • Spectral sampling: 0.5 nm. Spectral resolution: 0.58 nm

Available on all sites:
