In countries like Finland—where the large amount of water bodies would imply enormous associated costs for authorities to use traditional monitoring methods across the entire nation—the use of satellite data are particularly helpful.

Within the framework of the 'Copernicus Sentinels Benefits Study' (SeBS), which is funded by the EU and ESA, Copernicus Sentinel-2 and Sentinel-3 data are being used to monitor Finland's water bodies.

These measurements allow the environmental institute of Finland and regional environmental agencies, known as ELY Centres, to monitor the quality of water in lakes throughout their region to a degree that would not be possible using traditional in-situ water sampling and testing.

ELY Centres are located in each of the regions of Finland, which use SYKE’s (the Finnish Institute for the Environment) service as part of their lake quality management responsibilities and for reporting to national/international level entities. They also share the information on lake water quality on their TAARKA websites.

Sentinel data from the European Union’s Copernicus Programme is helping authorities to improve water quality at a lower cost, which in turn boosts the condition of life for citizens, aids in the protection of biodiversity and helps to ensure environmental sustainability.

Sentinel data help regional authorities and the Finnish environmental institute to monitor the lakes more effectively, more frequently and more comprehensively.

Offered through a publicly available platform, the Sentinel data enable better informed economic and leisure activities and lake ecosystems are better protected. The associated benefits are important and will grow significantly in the next five to ten years.
