Monitoring of the atmospheric ozone layer and natural ultraviolet radiation: Annual Report 2022

Om publikasjonen

This report summarizes the results from the Norwegian monitoring programme on stratospheric ozone and UV radiation measurements in 2022.

The ozone layer has been measured at three locations since 1979: In Oslo/Kjeller, Tromsø/Andøya and Ny-Ålesund.

The UV measurements started in 1995. The results show that there was a significant decrease in stratospheric ozone above Norway between 1979 and 1997. After that, the ozone layer stabilized at a level ~2% below pre-1980 level.

The year 2022 was characterized by annual average total ozone values slightly below “normal”.
