Arctic

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. 


Blue-Action (Arctic Impact on Weather and Climate) - Horizon 2020

Blue-Action is coordinated by DMI (Dr. Steffen M. Olsen)

Cordis: https://cordis.europa.eu/project/id/727852


Project aims:
Businesses, policymakers, and local communities need to access reliable weather and climate information to safeguard human health, wellbeing, economic growth, and environmental sustainability.

However, important changes in climate variability and extreme weather events are difficult to pinpoint and account for in existing modelling and forecasting tools. Moreover, many changes in the global climate are linked to the Arctic, where climate change is occurring rapidly, making weather and climate prediction a considerable challenge.

Blue-Action evaluates the impact of Arctic warming on the northern hemisphere and develop new techniques to improve forecast accuracy at sub-seasonal to decadal scales. Blue-Action specifically works to understand and simulate the linkages between the Arctic and the global climate system, and the Arctic’s role in generating weather patterns associated with hazardous conditions and climatic extremes.

In doing so, Blue-Action aims to improve the safety and wellbeing of people in the Arctic and across the Northern Hemisphere, to reduce the risks associated with Arctic operations and resource exploitation, and to support evidence-based decision-making by policymakers worldwide.

DMI's role: DMI is involved in most aspects of the project including science coordination and project management.

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.

Funding: The Copernicus Climate Change Services (C3S) programme, which is a programme initiated by the EU commission.

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.
