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:

* UVA pyranometer - Calibrated to provide:
- Global solar UVA irradiance. Wavelength integration: 315-400 nm and 320-400 nm
- Time sampling: 1 minute (or better: down to 3s)
* UVB pyranometer - Calibrated to provide:
- UV index measurements
- Global solar UVB irradiance. Wavelength integration: 280-315 nm and 280-320 nm
- Time sampling: 1 minute (or better: down to 3s)
* Total Solar Pyranometer (TSP) - Calibrated to provide:
- Global solar irradiance. Wavelength integration: 300 - ~2800 nm
- Time sampling: 1 minute (or better: down to 3s)
- Multi-channel filter radiometers (GUV-2511) manufactured by [BIOSPHERICAL Inc](https://www.biospherical.com) - Global solar irradiance at the following wavelengths:
