Traceability for surface spectral solar ultraviolet radiation

The European project, coordinated by the SFI-Davos (Switzerland), aims to develop methods for measuring direct, diffuse and global solar spectral irradiance between 290 nm and 400 nm with an uncertainty of 1% to 2% and new instruments for rapid measurement of spectral irradiance (UV to TF spectroradiometers) to take into account rapid variations in atmospheric conditions (measurement duration less than 10 s and repetition time less than 1 min).
