Springtime evolution of stratospheric ozone and circulation patterns over Svalbard archipelago in 2019 and 2020
The polar vortex was exceptionally intense and persistent in late winter and spring 2020. The unusually cold lower stratosphere subsequently enabled ozone depletion over the Arctic. The behaviour of ozone layer and stratospheric parameters at the Ny-Ålesund station in the late winter and spring 2019...

The polar vortex was exceptionally intense and persistent in late winter and spring 2020. The unusually cold lower stratosphere subsequently enabled ozone depletion over the Arctic.
