Sentinel-3A and Sentinel-3B radar altimetry water surface elevation in the Zambezi catchment [Data set] C. M. M. Kittel, L. Jiang, C. Tøttrup, and P. Bauer-Gottwein

Short summary
In poorly instrumented catchments, satellite altimetry offers a unique possibility to obtain water level observations. Improvements in instrument design have increased the capabilities of altimeters to observe inland water bodies, including rivers. In this study, we demonstrate how a dense Sentinel-3 water surface elevation monitoring network can be established at catchment scale using publicly accessible processing platforms. The network can serve as a useful supplement to ground observations.
