ACTRIS Sweden, ICOS Sweden and SITES provide Sweden with long-term environmental observations, advanced measurement capabilities and research facilities spanning the land, inland waters, ocean and atmosphere. ICOS (Integrated Carbon Observation System) and ACTRIS (Aerosol, Clouds, Trace gases Research Infrastructure), which quantify the exchange of long-lived greenhouse gases and short-lived climate gases within the landscape, respectively, complement the terrestrial and aquatic ecosystem focus of SITES.
Visit the actris-icos-sites webpage for details on the collaboration between the three RIs.

Several SITES stations – Abisko (Stordalen), Svartberget (Degerö, Svartberget), Skogaryard (Mycklemossen – are co-located with ICOS and ACTRIS. Thus, in addition to SITES, users have access to ICOS and/or ACTRIS at these stations as well as co-located open data.
Co-located ICOS data connected to SITES stations can be found on SITES Data Portal by searching for “ICOS” under the Data Type tab. When using co-located data, please, acknowledge ICOS in addition to SITES, following SITES Data Acknowledgment and ICOS SE Data and Acknowledgment.
