European stratospheric monitoring stations in the Arctic II (ESMOS/ARCTIC II)

The Norwegian contribution consists of modelling work and measurements of stratospheric trace gases with UV-vis spectrometer. The project addresses the issues of arctic ozone depletion and its causes. Changes of the composition of the arctic stratosphere will be observed by a network of stations and determined by performing long-term measurements and model calculations.
Note: The instrument was moved from Ny-Ålesund to Andenes in 1997.
