Network for the Detection of Atmospheric Composition Change (NDACC)

The Danish Meteorological Institute (DMI) operates in cooperation with the Danish Energy Agency and the Danish Ministry of the Environment three NDACC-stations in Greenland: at Pituffik/Thule Air Base (until 2017), at Kangerlussuaq/Sondre Stromfjord and at Illoqqortoormiut/Scoresbysund.

Information on the location and on instruments available at each station is available from the menu or click on image below. Near Real-Time data can be found under 'Measurements'. Notice however that only data for which the DMI is responsible are updated on a daily basis.

DMI's observatories in Greenland (Thule and Sondre Stromfjord) has served as arctic stations in the world wide "Network for the Detection of Atmospheric Composition Change" (NDACC). The observatories included in this network of stations are all equipped with instruments of high quality for monitoring the state of the stratosphere, and processes leading to chemical ozone loss. Besides groundbased ozone and NO₂-observations DMI conducts ballon borne ozone soundings and spectral measurements of the UV radiation. In addition to DMI's own instruments DMI's observatories host instruments from international collaborators, including e.g. a LIDAR for measurements of stratospheric aerosols (University of Rome, Italy ) and cloud particles and an infrared spectrometer for detection of important stratospheric molecules.
