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
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 (www.euro-argo.eu). 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.
https://argo.ucsd.edu/data/data-from-gdacs/ in the US or https://www.coriolis.eu.org/Observing-the-Ocean/ARGO in Europe.
First floats will be deployed in 2023 in NE Greenland. Near real time data can be visualised via the fleet monitoring tool. https://www.euro-argo.eu/Argo-Data-access.

Abstract: Pituffik is a newly established geomagnetic observatory located in the high Arctic – a region with sparse geomagnetic observational coverage. Positioned within the polar cap at Quasi-Dipole geomagnetic coordinates 83.19° latitude and 25.25° longitude, the observatory provides valuable data from a geophysical significant area. The observatory was carefully designed and constructed using non-magnetic materials with special considerations for the Arctic conditions. All building components were pre-assembled and tested in Denmark before being disassembled, shipped, and reassembled at the remote site in northwest Greenland. This paper presents the observatory design, and an analysis of over one year of operational data, including baseline stability, temperature control, and calibrated vector and scalar magnetic field measurements. The results demonstrate stable baselines and high data quality, confirming the observatory’s readiness for data-distribution to the international geomagnetic community.
Data from GEUS
Glaciological data from Greenland (PROMICE)
The Greenland Ice Sheet is monitored by 25 fully automatic stations which measure the ice melt, the climate and ice movement, and then transmit the data to GEUS in Copenhagen via satellite. The programme focuses on what is happening along the rim of the ice sheet where the mass loss from melting and calving of icebergs take place.
More information on the data can be found here: PROMICE/GC-NET https://promice.org

Data from Asiaq
Asiaq has extensive knowledge of the construction and operation of weather stations for both private and public clients. Our equipment comes from established suppliers and our own, competent workshop, and is well adapted to the arctic environment. The measured weather data is sent directly to our servers via satellite or mobile network, and can be monitored on a daily basis.
Asiaq operates a network of weather stations on the west coast of Greenland, in cooperation with Greenland Airports and the Danish Meteorological Institute. The weather observations are continuously updated here: http://vejr.asiaq.gl/#/map
