takes part in monitoring of UV radiation in both hemispheres at locations, where polar ozone loss has been detected. In this work UV data from Sodankylä (67 N) and Jokioinen (61 N) have been used to represent the Arctic, and UV data from Marambio (64 S) and Ushuaia (54 S) represent the Antarctic. Maximum UV index values of the studied period are around 5 and 6 in Sodankylä and Jokioinen, respectively, whereas maximum UV index values can exceed 7 and 9 in Marambio and Ushuaia, respectively. Arctic data In the Arctic, in Finland, the FMI has UV measurements using broad band SL501A radiometers, multiband NILU-UV radiometers and Brewer spectrophotometers. In this study Brewer measurements from Jokioinen and
