The ICOS-Norway infrastructure interaction mechanisms.


The ocean component measures CO2 concentration in the surface ocean using measurements from marine ICOS stations for quantifying the air-sea flux, man-made CO2 content, and its effect as Ocean Acidification.

The ocean component is operated by the University of Bergen (UiB), Uni Research, and the Norwegian Polar Institute (NPI).

The atmospheric component provides measurements of carbon dioxide, methane, carbon monoxide and nitrous oxide in the atmosphere at Birkenes Observatory (Aust-Agder, southern Norway) and Zeppelin Observatory (outside  Ny-Ålesund, Svalbard) for understating of changes, variations in these components on long-term as well as shorter times scales. Both observatories have a comprehensive measurement program including numerous of atmospheric components for the detection of atmospheric change.

NILU - Norwegian Institute for Air Research has carried out observations of atmospheric composition at these sites since the 1970s and 1980s and will coordinate the atmospheric measurements for ICOS Norway.

The ecosystem component measures the exchange of the uptake by the boreal forests in southern Norway.

NIBIO - Norwegian Institute of Bioeconomy Research is operating the ecosystem component.

The integration component aims to assemble all measurements into an inversion model to constrain the net CO2 and CH4 balance of Norway.

NILU is leading the integration component.

The coordination ensures the ICOS Norway to achieve its goals by guiding the implementation of the infrastructure and interact and liaise with both the national network and the wider ICOS RI.
