ICOS-Norway is the integrated Norwegian component of Integrated Carbon Observation System (ICOS). The infrastructure will, after installation and updates of measurement instrumentation, deliver high-quality carbon data from different sites and platforms from Norwegian territories. These include towers for air measurements in southern Norway and at Svalbard, a forest station in south-eastern Norway, and the use of two research ships and two commercial ships in the North Atlantic, the Nordic Seas, and areas around Svalbard. When everything is up and running at these sites all data will be thoroughly quality controlled. Data from the various platforms will be integrated and made available, in usable format, to carbon system scientists and various interested parties such as research communities, national agencies, oil and energy companies, and fisheries.
