Reactive Trace Gas in-situ instruments for ACTRIS Sweden

Within the framework of the Swedish national research infrastructure ACTRIS Sweden (www.actris.se) we are equipping five stations and one mobile platform with instruments that measure reactive trace gases, including NOX, SO2, O3, and at some stations also a range of volatile organic compounds (VOC). The long-term observations of these trace gases are performed at regional background stations, often at trace levels. When relevant, we follow the recommendations from the European ACTRIS ERIC (actris.eu).
