Data from Greenland Gradient – ARC/AU

Data from our ARC-MO (Arctic Research Centre – Mobile Observatory at Aarhus University) units is released near real time and is not calibrated. Use of data will be at own risk. Data will be downloaded manually once a year during technical service of our units, calibrated and reported on this site. More details on the ARC-MO system can be found in: Rysgaard et al. (2022) A mobile observatory powered by sun and wind for real time measurements of atmospheric, glacial, terrestrial, limnic and coastal conditions in remote off-grid areas. HardwareX.

Data from DTU Aqua

Data from DTU Aqua

DTU Aquas contribution to GIOS is to establish sustained oceanographic observations from the Greenland shelf. This will be achieved by developing a national program to maintain and facilitate deployment ARGO floats as well as the development of new hybrid solutions. Via GIOS and the Danish Centre for Marine Research, Denmark is now a member of the European Infrastructure Research Consortium (ERIC) for the ARGO program ( The data from the oceanographic floats deployed as part of GIOS (together will all ARGO data) will be freely available from the global data acquisition centres. in the US or in Europe.

First floats will be deployed in 2023 in NE Greenland. Near real time data can be visualised via the fleet monitoring tool.

DTU Space data

Data from DTU Space

DTU Space provides data in forms of magnetograms of the magnetic variation along the local magnetic north component (H), the local magnetic east component (E), and the vertical component (Z). The plots below show magnetograms from the latest 24 hours from the following magnetometer stations:
