Monitoring of the atmospheric ozone layer and natural ultraviolet radiation. Annual report 2015. NILU report

Svendby, T.M.; Hansen, G.H.; Edvardsen, K.; Stebel, K.; Dahlback, A.

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.

smelter. The model results show that the impact is in compliance with the limit values for the environment for all components except for hydrogen fluoride. The guideline for effect of hydrogen fluoride versus vegetation is exceeded in an area covering 25 km2, inclusive of the factory area and areas at sea. Impacted land area outside the plant is 11,5 km2. Emission from the roof of the production hall contributes 95 % of the total concentration within the area of exceedance.

One of NILU's main goals is to study the impact of pollution and supply decision-makers with a sound scientific platform for choosing measures to reduce the negative impacts. Furthermore, it is very important for the institute to have control of the impact the institute¿s own activities may have on the environment and to reduce negative impacts as far as possible.
NILU has for many years been working to improve the status of the environment and to reduce negative impacts. In order to take this one step further, it was decided that the institute should restructure the work according to a relevant environmental standard and to seek certification according to the same standard.
The chosen standard is ISO 14001:2004 (Environmental management systems - Requirements with guidance for use) and NILU achieved certification according to this standard in October 2010. This report summarizes the results of the system in 2015.
