European Space Agency to Elevate Finnish Arctic Space Centre into Advanced Environmental Monitoring Supersite

In a groundbreaking venture in the context of Earth observation, the European Space Agency (ESA) is set to transform the Finnish Meteorological Institute’s Arctic Space Centre in Sodankylä, located in the northern expanse of Finnish Lapland, into a cutting-edge ‘supersite.’ This initiative, in collaboration with local industrial partners, aims to strategically position the site with advanced environmental monitoring technologies, including a remarkable high-tech airship designed to conduct extensive surveys of the region.

Nestled above the Arctic Circle and enveloped by expansive boreal forest, the Arctic Space Centre provides a unique environment that embodies the characteristics of the boreal forest biome—the largest terrestrial ecosystem, sprawling across northern regions including Canada, Scandinavia, and Russia. This makes the facility an ideal platform for enhancing satellite-based Earth observation capabilities, allowing for deeper insights into environmental changes.

The upgrade to a supersite signifies significant advancements for the collection and analysis of environmental data. The integration of new ground-level sensors alongside aerial survey capabilities will offer invaluable data on the functioning of boreal forests and their responses to environmental shifts. Additionally, this venture will foster superior quality of satellite data, facilitating meaningful comparisons between satellite observations and terrestrial measurements in this ecologically critical region.

The new supersite is poised to create fresh avenues for Finnish enterprises focused on developing and testing novel environmental sensing technologies, enabling them to benchmark their innovations against established reference sensors. Improved satellite data quality arising from this initiative is expected to lead to the development of tailored services and applications for the Arctic.

Following a contract signed during the ESA Living Planet Symposium last year, and subsequent evaluations, the agency is moving ahead with the procurement and installation of new sensing tools at Sodankylä, coupled with airborne monitoring operations backed by its FutureEO program. Malcolm Davidson, head of ESA’s Earth Observation Campaigns, emphasized the strategic importance of the supersite in bolstering Europe’s capabilities to monitor the Arctic from space, particularly with upcoming missions such as the Copernicus Anthropogenic Carbon Dioxide Monitoring and Copernicus Radar Observing System.

Hannakaisa Lindqvist, leading the initiative for the Finnish Meteorological Institute, shared insights on new instruments set for the site, including a multifrequency radiometer and innovative greenhouse gas sensors. Plans also include the deployment of a remotely-controlled airship, which will generate the first three-dimensional vegetation map surrounding Sodankylä over flights lasting up to 12 hours.

Finland’s SpacEconomy project, a strategic initiative aimed at elevating the national space ecosystem, is also a key player in this development, seeking to involve companies not traditionally aligned with the space sector, thus bridging connections between diverse industries and ESA’s activities.
