UV Radiation at Robert Island, South Shetland, Antarctica

Solar ultraviolet radiation measurements by means of chemical actinometry and spectroradiometric instrumental were carried out at the Risopatron base at Robert Island, Antarctic, during January 1996. The maxim irradiance of the UV-A and UV-B spectral range were detected between 13:00 and 14:00 hrs (local time) under clear sunny days. The actinometric measurements agree our spectroradiometric determinations and let us propose this method for local and regional scale measurements after comparing these results to those developed in the Chilean southamerican territory.
