European Ultraviolet Calibration Center (EUVC)
A GAW regional UV calibration center for the European region (WMO RA VI (Europe)) has been established at PMOD/WRC since January 1, 2008.
Its main function is to ensure that the data submitted to the GAW World UV data Centre (WOUDC) operated by the Meteorological Service of Canada in Toronto is of known and adequate quality to meet the needs of the scientific community.
By its activities, the EUVC aims at improving the data quality in the European GAW UV network and at harmonising the results from
different stations and monitoring programs in order to ensure representative and consistent UV radiation data on a European scale.
The specific goals of the EUVC are to:
- Maintain a set of reference irradiance standards and ensure their traceability to the SI units through purchase and intercomparison of
transfer standards traceable to primary irradiance standards held at National Metrological Institutes (NMIs).
- Perform intercomparisons of irradiance standards between regional calibration centers as well as UV monitoring institutes.
- Maintain and operate a transportable reference spectroradiometer for the routine quality assurance and calibration of spectroradiometers
measuring spectral solar UV irradiance. Perform calibrations and quality assessments of spectroradiometers operated by UV monitoring stations through regular site visits.
- Maintain and operate a calibration center for the characterisation and calibration of UV filter radiometers.
- Provide on-site training and expert advice to station personnel to help maintain the required data quality.
The instrumentation of the EUVC is made available by the Joint Research Centre of the European Commission in Ispra , Italy under the cooperation agreement 2004-SOCP-22187.
