Belgium

Belgium is active in the UV monitoring and instrument development field. There are a variety of UV monitoring instruments in Belgium, inlcuding a multi-band instrument developed for use in 1996 which measures the following 10 wavelength channels: (300.3, 310.5, 318.7, 368.5, 501.3, 615.3, 674.6, 781.8, 1038.7; in the UV regions these channels have bandwidths of between 2.2 and 2.7 nm (FWHM). A total of 13 instruments are being operated by the Institute d'Aeronomie Spatiale de Belgique (IASB); The Belgian Institute for Space Aeronomy. Three of these instruments are modified Jobin Yvon HD10s and measure total irradiance, direct irradiance and diffuse irradiance. Measurements are taken every 15 minutes for solar zenith angles less than 100 degrees. A fourth instrument is a YES Model UVB-1. These instruments went into operation in March of 1993. In addition, a UVA-1 and a TSP-1 from Yankee are in operation in Brussels. A SPUV-10 from YES has now been operational since March 1996. There is now monitoring in the town of Redu, near Libramont, where three instruments are located.
All instruments operate in support of an entire network of European instruments and soon will join the NDSC , the Network for the Detection of Stratospheric Change. Data from many of the stations is supplied to the European UV Database (EUVDB). Please contact Dr. Didier Gillotay for more information on IASB monitoring or to request data .

The Royal Meteorological Institute of Belgium (RMI) continues to operate two instruments in Belgium; both spectral Brewers located in Uccle. These instruments both undergo regular calibration and participate in intercomparison exercises. Funding is provided by Federal Services for Science Policy. Please contact Hugo De Backer for more information on RMI monitoring.
