EO provides the opportunity to monitor bodies of water, i.e. inland waters, and to assess ground water and run-off. For lakes, this includes products about water quality, pollution, turbidity, suspended sediment concentrations (quantitative, qualitative), waterbody (temperature, extent, volume, quantity), algal blooms, alkaline water, evaporation, surface temperature. For ground water and run-off, the products focus on water run-off (water quantity), hydrological network and catchment areas (water catchment), run-off season, groundwater. Various scales are addressed, from local catchments to the global water cycle. For inland water quality, sensors are optical medium resolution (300 meters) for achieving a (strongly cloud-cover dependent) update frequency of 10-20 times per year and high resolution (5 meters) for update frequency of 3-5 times per year.
