It is becoming an indispensable tool for oceanography as a new generation of radar altimeters providing higher resolution and precision is poised to begin service. Remarkable progress has been made since launch of the pioneering ERS-1 in 1991.

Monitoring river and lake levels from space / J. Benveniste in ESA bulletin, n° 117 (February 2004)

The most direct measurements of inland water heights are obtained from satellite altimeters, with long time series of such observations having been built up over the post decade. ESA has been developing new global river and lake monitoring products, including an expert processing system, with the help of De Montfort University (UK). A seven-year-long time series of samples was distributed to the hydrology community at the CNES Hydrology from Space Workshop in Toulouse last October in order to validate the user requirements. They responded very favorably and are now impatient to get their hands on a decade of global river-and lake-level products, as well as the latest near-real-time products coming from ESA's Envisat mission.
