As part of the Commonwealth of the Realm of Denmark DMI has a long tradition studying, monitoring and forecasting Greenland’s weather, atmosphere, ocean, ice and climate. Further, climate change is more pronounced in the Arctic than almost everywhere else on the globe. It is therefore important to assess potential future Arctic changes using climate models.
Many lines of research at the DMI are centered around the Arctic. DMI is responsible for forecasting the weather, ocean , ice and wave conditions for Greenland, and thus runs numerical weather, ocean-ice and wave prediction models for Greenland and provides official forecasts. DMI participates in a number of climate studies in the Arctic, including coupled atmosphere -ice sheet modelling as well as ocean and sea ice studies with focus on Greenland fjords, the surrounding waters and the Arctic Ocean.
Atmosphere and ocean climate models are run over numerous Arctic domains and coupled atmosphere, ocean, ice sheet and permafrost models are developed. The arctic stratosphere, which is determining for the ozone layer over the Northern Hemisphere, is a long-standing research area at DMI. Finally, DMI researchers are part of the team behind the outreach web site polarportal.org and take part in several expert groups on short-lived climate pollutants (SLCPs) in the Arctic.
Increasing economic activities in the Arctic waters such as maritime transport, offshore oil and gas exploitation and fishery have raised new research challenges such as e-navigation, environmental protection and ice service. Combing modeling, remote sensing and in-situ monitoring, DMI has been actively developing integrated Arctic System science for serving a variety of social benefit areas.
ARCPATH (Arctic Climate Predictions: Pathways to Resilient, Sustainable Societies)
Project aims: To improve Arctic climate prediction by reducing uncertainties originating from changes in the cryosphere and the ocean, and to explore Arctic climate sensitivity to anthropogenic forcing; To increase understanding and reduce uncertainties regarding how changes in climate interact with multiple societal factors including the development of local and regional adaptation measures; To supply this knowledge as potential “pathways to action” to the specific Arctic regions singled out for special focus in the project.
DMI's role: DMI will work together with SMHI to develop the EC-Earth seasonal to decadal prediction system with ocean+sea ice assimilation; DMI will also perform high resolution prediction experiments to assess the importance of higher model resolution for better climate services for the Arctic communities.
CARRA (Copernicus Arctic Regional ReAnalysis)
Project aims: A 24-year reanalysis with the same regional model setup will be implemented and run on two complementary domains to cover the European sector of the Arctic. This will be done with the HARMONIE-AROME model running at 2.5 km resolution. The project is planned for four years duration and starts with a design and setup phase, then the reanalysis enters production in Month 20. The reanalysis dataset will be continuously updated to provide a complete 24 years time series before the end of the project. The work also includes a proof-of-concept Pan-Arctic reanalysis to be run for one year duration.
DMI's role: DMI leads WP1, the work package on system development. DMI participates in all most task within WP2, the work package on input data, and will lead the WP2 tasks 2.1, 2.2 and 2.3 on physiography, glacier input and albedo, and SST and sea ice, respectively. Additionally, DMI will be responsible for the reanalysis production (part of WP3) for one of two CARRA model domains. This domain covers Greenland, Iceland and a few of the adjacent islands in the high Arctic. Met.no will be responsible for the reanalysis production in the other domain that covers the Barents Sea, Svalbard and Northern Scandinavia. Finally, DMI will contribute to WP4 on user guidance and support, in which documentation and guidance on the available products from the service will be made.

eSTICC: eScience Tools for Investigating Climate Change at High Northern Latitudes (Link: english (external))
Project aims: The overarching goal of eSTICC is a more accurate description of the high-latitude feedback processes in the climate system via further development of the eScience tools of the climate research community. It brings together climate researchers and scientific computing experts in Nordic countries to develop eScience tools needed for more efficient use of experimental and model data, and to improve the computational efficiency and coding standards of ESMs and of the tools used for inverse modeling of emission fluxes.
DMI’s role: DMI will work on improving the interface to the model data archive (CORDEX/ENSEMBLE), improving representation of ice sheets and their surface mass balance in ESM-Ice Sheet Model coupling system, improving the performance of the ESM (i.e., EC-EARTH) for carrying out extended long (millennial time-scale) experiments.
Funding: Nordic Top-level Research Initiative (TRI)
Period: Jan. 1, 2014 – Dec. 31, 2018
Collaborators: eSTICC is led by the Norwegian Institute for Air Research (NILU), and gathers 13 research groups from the Nordic countries working in the fields of climate research and/or eScience, including the most prolific groups from the existing Nordic Centers of Excellence CRAICC, DEFROST and SVALI.
Monitoring the Ozone Layer and the Solar UV radiation in Greenland (link: danish (external))
Project aims: To continue the monitoring that was started in the early 90'es in order to fulfill the danish obligations to the "Vienna Convention for the Protection of the Ozone Layer". Part of the network for the Detection of Atmospheric Compostion Change (NDACC).
DMI’s role: To measure the Ozone Layer and the solar UV radiation at three locations in Greenland, at Thule/Pituffik, Scoresbysund/Ittoqqortoormiut and Sondre Stromfjord/Kangerlussuaq.
OSI SAF (Link: www.osi-saf.org )
Project aims: Project aims: For complementing its Central Facilities capability in Darmstadt and taking more benefit from specialized expertise in Member States, EUMETSAT created Satellite Application Facilities (SAFs) based on co-operation between several institutes and hosted by a National Meteorological Service.
The Ocean and Sea Ice Satellite Application Facility (OSI SAF) is an answer to the common requirements of meteorology and oceanography for comprehensive information on the ocean-atmosphere interface. One of the objectives of the OSI SAF is to produce, control and distribute OSI SAF operational products in near real-time using available satellite data.
DMI’s role: DMI is part of the High Latitude center (in cooperation with met.no) responsible for the production and distribution of the OSI SAF Sea Ice products, in particular: global sea ice concentration, global sea ice emissivity, medium resolution ice drift, and ice surface temperature.
