Cover Story: Radar altimetry not only provides information on the surface elevation but also on the nature of the land surfaces via the radar echo and derived parameters as the backscattering coefficient. The presence of water was detected along the altimeter groundtracks using an unsupervised classification approach on the backscattering coefficient. From this detection, a dense network of altimetry-based water level stations was built over the rivers and wetlands in the center of the Congo Basin. Comparisons against manually generated altimetry-based stations showed a good agreement between the two sources of water levels. Lower annual amplitude of the water levels was observed over the wetlands than over the rivers. The inclusion of changes in water levels over the wetlands has a strong implication for surface water storage estimates. View this paper
