Network for Detection of Atmospheric Composition Change

NDACC

 

 

 

 

 

 

The Danish Meteorological Institute (DMI) operates three  NDACC-stations in Greenland: at Pituffik/Thule Air Base,  at Kangerlussuaq/Søndre Strømfjord and at Illoqqortoormiut/Scoresbysund.

Additional info on the location and on instruments available at each station may be found from the links.

 

Near Real-Time data can be found from the links below as graphs.

 

Notice however that only data for which the DMI is responsible are updated on a daily basis.

DMI's observatories in Greenland (Thule and Søndre Strømfjord) serve 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.
