Summary
A physics-based component-wise simulation framework decomposes Sentinel-3 radar altimetry waveforms into river and interference contributions using topography and water masks. Across 55 validation virtual stations, it reduced median unbiased root-mean-square error (ubRMSE) to 0.47 m, outperforming standard retrackers and recovering water levels at complex reaches where operational databases routinely discard observations.
