The atmospheric monitoring and research station at the Norwegian Troll site in Queen Maud Land, Antarctica, aims at providing year-round information on atmospheric conditions and composition from the transition region between the coastal zone and the ice plateau in Antarctica. In June 2003, the Norwegian Ministry of the Environment decided to upgrade the station and provide it with a runway for airplanes, the Troll Airfield, enabling year-around operation. The new station was officially opened in February 2005 by Her Majesty Queen Sonja of Norway. The Troll Station can house up to 8 persons for wintering. The main all-year activities at Troll Station are a satellite receiver station operated by Kongsberg Spacetec and the Atmospheric Monitoring and Research Station Troll-Air run by NILU. First atmospheric measurements were performed by NILU in austral summer 2004/05 with pilot measurements of UV radiation and black carbon.
The main atmospheric facility was established in January 2007 and is located in a separate container set about 200 m away from the main station building. After one year of routine operations, the suitability of the site will be assessed with respect to local contamination.
