Using knowledge about how certain substances, such as one of the main pigments of the phytoplankton (Chlorophyll a - Chl a)alter the colour of the water, these parameters can be derived from optial Earth Observation (EO) satellite sensors. Water Insight provides monitoring services of Chl a based on EO data which is validated with in situmeasurements. Also the maps of WFD phytoplankton biomass status classes are created, by application of the WFD tresholds on Chl a as a proxy for phytoplankton biomass. The maps are made available in a portal, which allows to follow the lakes in time, zoom and download maps and time series. Wind maps retrieved from Synthetic Aperture Radar are availabe for users to browse and download in near-real-time (i.e. within 24 hours of the satellite data acquisition). The maps are snapshots of the wind speed 10 m above the sea surface. They reveal the offshore wind variability in great detail and show effects of the land, offshore wind farms, and other structures on the wind flow. Wind resource maps calculated annually from DTU’s entire archive of satellite based wind maps are also available to the users. |
