    dct:description "Defined as the height, in meters above the geoid, of the reflecting surface of continental water bodies. It is observed by space radar altimeters and data are available at global scale in near real time in vector format with the temporal extent from 2002 to present. These are mapped products or observation time series, not weather forecasts or terrain height grids. Published archive extent and cadence do not guarantee valid pixels everywhere or continuous real-time observations." ;
