Total ozone loss during the 2015/16 Arctic winter and comparison to previous years
International audience The amplitude of column ozone depletion in the Arctic is monitored every year since 1994 by comparison between total ozone measurements of eight SAOZ / NDACC UV-Vis spectrometers deployed in the Arctic and 3-D chemical transport model simulations in which ozone is considered a...
