Short summary
The study deals with ultraviolet (UV) radiation in southern polar conditions, where ozone depletion occurs each spring. A 10-year-long time series of UV spectra from Marambio Base, Antarctic Peninsula, has been studied, with a focus on the changes of UV radiation at different wavelengths and the effects of atmospheric and terrestrial variables like ozone, solar elevation, or cloudiness. At the very short wavelengths, the effect of ozone and its deficiency was clearly observed.
