Deliverable 2.7 Final report on number of long-term preserved datasets (T2.6)

The key motivation of the Arctic PASSION project is to contribute to the co-creation and implementation of a coherent, integrated Arctic observing system. It aims to overcome known flaws in the present observing system by refining its operability, improving and extending pan-Arctic scientific and community-based monitoring and the integration with Indigenous and Local knowledge. It also aims at streamlining the access and interoperability of Arctic Data systems and services and contribute to ensuring the economic viability and sustainability of the observing system. As part of the H2020’s Open Research Data Pilot[1], the Data Management Plan for the Arctic PASSION project has been designed to provide the consortium partners with a state-of-the-art data handling workflow that adheres to the FAIR data principles (ensuring that data are Findable, Accessible, Interoperable and Re-usable). All datasets generated or mobilised during the course of the project have been curated and archived by expert data editors in trusted FAIR repositories, improving the long-term preservation and integration of Arctic data and information. Specifically, all processed datasets have been enriched with standardised discovery and use metadata to simplify the reuse of data across providers, standardised web services, applications, protocols or data portals. These represent essential optimisation steps along the data value chain, supporting the process of making data machine-actionable and fit for in order to feed it into decision support systems and inform policy. This benefits not only Arctic communities, but also European and global communities.

To date, a total of 150 Arctic PASSION-related datasets, ranging from atmospheric to ice and oceanographic measurements, have been curated and successfully archived. Of these, 129 datasets (Table 1) have already been published in five trusted data repositories: PANGAEA – Data Publisher for Earth & Environmental Science[2] (119 records), Zenodo[3] (four records), the Norwegian Polar Institute[4] (three records), the Norwegian Meteorological Institute[5] (two records), the Italian Arctic Data Center[6] (one record). These include priority datasets fuelling the Arctic PASSION Pilot Services, such Alex[7] (Nitze et al. 2024, 2025) and AURORAE[8] (Cuzzucoli et al. 2025). An additional 21 Arctic PASSION-related datasets are currently pending final publication (Table 2). These datasets include measurements from various sea ice mass balance buoys as well as from automatic weather stations and are now in the final processing step before receiving a permanent DOI. the World Meteorological Organization's (WMO) Global Telecommunication System (GTS) and associated with the Arctic PASSION project are still pending publication following GTS conversion. At the time this report was concluded, the CORDIS EU research results project website for Arctic PASSION still displayed an incomplete list of all project-related data publications compiled via the OpenAIRE service (three records listed). However, the authors of this report have compiled a complete list of all published Arctic PASSION datasets, which are currently pending processing and curation by OpenAIRE services for subsequent final linkage and display in CORDIS.
