    dct:description "Daily 500 m lake-ice classifications across the published global grid. Cloud, water and no-data classes and source flags must be interpreted separately from ice observations. These are observations or derived estimates, not weather forecasts. Published cadence is distinct from continuous real-time availability." ;
