The development of compact, stable, portable, and robust monitoring sources based on state-of-the-art, commercially available UV light-emitting diodes (LEDs) is one of the tasks within the European Metrology Research Programme (EMRP) Project Traceability for surface spectral solar ultraviolet radiation aimed towards shortening the traceability chain and reducing the uncertainties of spectral solar UV radiation measurements in the wavelength range 280 nm to 400 nm. These sources will be used to maintain the spectral calibration of spectroradiometers while deployed at the solar UV measurement sites. As a first step, commercially available UV-LEDs have been selected and characterized with respect to their stability and spectral properties.
