Lake and reservoir water levels, satellite altimetry (CNES Hydroweb)

Water-level time series for lakes and reservoirs worldwide measured by satellite radar altimetry (CNES/LEGOS Hydroweb via hydroweb.next): height above the reference geoid in meters per satellite pass (~10-27 day revisit), plus surface area and relative storage volume for some water bodies. Operational stations reach back to the 1990s. The signal for hydropower supply, irrigation reserves, and drought — reservoir drawdowns show up months before official water or power statistics.

In SQL, this dataset is the rows of satellite.series with dataset_code = 'satellite_water_levels'.
