The Lake Water Quality Products from the Copernicus Land Monitoring Service
Monitoring water quality in lakes and reservoirs is essential for assessing environmental conditions and supporting water resource management.
The Lake Water Quality Products (LWQP) from the Copernicus Land Monitoring Service enable consistent, large-scale observation of inland waters, reducing reliance on in situ monitoring. They provide key water quality parameters, including turbidity, trophic state, and surface reflectance. These together support the assessment of water clarity, biological productivity, and optical properties. The LWQP also provide observations every 10 days, made available in near real-time, at 100 m spatial resolution for a wide range of medium and large lakes.
This data visualisation, based on LWQP data, shows the turbidity in Lake Balaton, Hungary, for the period 21 February - 1 March 2026. Clearer waters are visible in blue and green tones, and more turbid waters in yellow and red.
