Horizon-2020 INTAROS – Final Online Meeting and Results

The final meeting of the Horizon-2020 Integrated Arctic Observation System (INTAROS; Dec 2016 – Feb 2022; https://intaros.nersc.no) project took place online on 24th February 2022, which attended more than 40 persons from the Partners of the INTAROS consortium. The project was coordinated by the Nansen Environmental and Remote Sensing Center (NERSC, https://www.nersc.no; Bergen, Norway) and 48 Organizations/Institutions were involved. The overall objective of INTAROS was to develop an integrated Arctic observation system (iAOS) by extending, improving and unifying existing systems in the different regions of the Arctic. The project had strong multidisciplinary focus, with tools for integration of data from atmosphere, ocean, cryosphere and terrestrial sciences. It assessed strengths and weaknesses of existing observing systems, contributed to elaboration of innovative solutions, developed platform to search/access data; elaborated a community-based observing systems (with merging local knowledge and scientific data). All this enables better decisions, strengthen socio- economical role of the Arctic and supports European strategy for the Arctic.

During the meeting, a series of presentations was delivered, and these included: observing systems for Arctic sea level changes; sea ice studies using drifting buoys; sea ice dynamic and thermodynamic processes involved in the genesis of Arctic ice minima; natural hazard assessment in the Arctic; observing climate and environmental changes in the Canadian High Arctic; results of the Greenland ice sheet studies; community-based observing systems; data systems in the Arctic – results from INTAROS and plans for further development; and others. During project lifetime in total more than 100 deliverables as the project reports and more than 100 peer-reviewed publications were delivered.

The INTAROS e-Catalogue (as a part of the iAOS Portal) includes more than 140 (540) datasets from 38 (47) Organizations/Institutions. INTAROS conducted a series of experiments in different regions of the Arctic, and collected various parameters in the atmospheric, marine, cryospheric, and terrestrial domains, as well as natural hazards, ecosystems, community-based monitoring themes.

The PEEX community contributed with the PEEX e-Catalogue. It is a collection of information on the Russian stations in the PEEX collaboration network, introducing an overview of measurements, metadata, and providing contact information. The catalogue is published in electronic format and conceived as a e-living document. Each station has lists of measured variables for atmosphere (meteorology and atmospheric composition), hydrosphere, pedosphere, cryosphere, fluxes, and other types measurements.

Moreover, the INTAROS project special session will be held on 28 March 2022 at the hybrid-format Arctic Science Summit Week (ASSW, https://www.assw.info; 26 March – 1 April 2022, Tromso, Norway).
