The biometer was installed in 1995 at Dumont dUrville to monitoring the evolution of ultraviolet radiation (UV) over this region and to evaluate the influence of ozone depletion on UV. The biometer at Dumont dUrville is working continuously since 1995. The French Polar Institute (IPEV Institut Polaire Français Paul-Emile Victor) supplies recurrent funding and logistics.
... Between 1995 and 2009 no calibration was performed. To ensure good quality data the instrument has to be calibrated regularly. A new biometer of the same model as the old one was installed in January 2008 at Dumont dUrville. The two instruments have been operated in parallel during a two months period, and then the 15 years old instrument was sent back to the laboratory in February 2008 for calibration. The calibration has taken place in a special laboratory equipped for certified UV-calibration at Davos, Switzerland in summer 2009.
