NOCOS DT developed sea ice research applications and models tailored to the unique conditions of the Nordic, Baltic and Arctic regions and contributed to the development of a global climate change information system. The modular and open nature of the project’s software products contributes to their reusability by the target stakeholders in the region and globally. Further development leveraging NOCOS DT’s achievements is already ongoing in projects such as the European Commission funded Digital Twin of the Earth System for Cryosphere, Land Surface and Related Interactions (TerraDT).
The legacy of NOCOS DT is reflected in the open source suite of operational and research tools it leaves behind, which can be integrated into other initiatives and platforms. From the daily RIO forecasts supporting safer ship navigation to the landfast and ridged ice toolboxes aiding regional climate resilience and planning, these outputs are designed for long-term usability and adaptability. The marginal ice zone definitions and toolsets offer tactical and strategic value for fisheries and climate studies, while the marine spatial planning tools enable data-informed decision-making as the Climate DT datasets mature. Additionally, the open availability of the HiDEM sea ice model fosters continued scientific exploration into ice dynamics and their interactions with infrastructure and ecosystems. Together, these contributions ensure that NOCOS DT’s impact will extend well beyond its project timeline, supporting both regional needs and global climate initiatives.
