Monitoring of the atmospheric ozone layer and natural ultraviolet radiation. Annual report 2015. NILU report
This report summarizes the results from the Norwegian monitoring programme on stratospheric ozone and UV radiation measurements. The ozone layer has been measured at three locations since 1979: in Oslo, 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 the 1979-1989 average. However, there are large inter-annual variations and in 2015 the average ozone level was close to the 1979-1989 average values at all three Norwegian stations.

Monitoring of greenhouse gases and aerosols at Svalbard and Birkenes in 2015 - Annual report. NILU report
The report summaries the activities and results of the greenhouse gas monitoring at the Zeppelin Observatory situated on Svalbard in Arctic Norway during the period 2001-2015 and the greenhouse gas monitoring and aerosol observations from Birkenes for 2009-2015.

NILU was commissioned by 8 Norwegian companies with FeSi-/Si-industry to perform passive air measurements of SO2 and PAH around the Finnfjord AS FeSi-smelter and to analyse microsilica dust samples from the companies.
Passive monthly samples were taken at 10 sampling sites around Finnfjord AS in the period October-December 2014. The PAH samples were analysed for 42 PAH compounds. 5-7-ring PAHs, i.e. particle bound components, were generally below the detection limit during the measurement period. There was no significant correlation of SO2 and PAH2-4-ring and thus no significant impact from the smelter was found in October-December 2014 for gaseous PAHs. An additional source of PAHs in winter was likely residential heating by wood burning.
