The biometer was installed in 2007 at Concordia to monitoring the evolution of ultraviolet radiation (UV) over the Antarctic plateau and to evaluate the influence of ozone depletion on UV. The biometer has been working perfectly until beginning of March 2008. Probably due to several electrical power failures, the temperature inside the UVB was no more regulated and decreased ... down to -60°C. The instrument has been severely damaged and is not working any more. There is no funding for the moment to replace the broken biometer.
