Atmosphere stations continuously measure data on greenhouse gas concentrations  in the atmosphere and basic meteorological conditions.  Additionally, descrete air samples are taken daily for possible analyses of other trace gases in the laboratory. ICOS Sweden operates three Atmosphere stations: HyltemossaNorunda and Svartberget

Parameters measured at ICOS Sweden Atmosphere stations. The measurements listed here, are those according to the ICOS Atmosphere station protocols; Please, check the individual station pages for information on additional measurements.
