Monitoring River Discharge Using Off-Nadir Altimetry-Derived Profiles and SAR-Derived River Width

This dataset provides supplementary materials supporting the manuscript “Monitoring River Discharge Using Off-Nadir Altimetry-Derived Profiles and SAR-Derived River Width”. The data enable reproducibility of the analysis and facilitate further research on river discharge using satellite altimetry. The dataset consists of the following components: Input_FFSAR Reach-scale water level, river slope, and river width derived from off-nadir processing and SAR imagery, used as the primary inputs for river discharge estimation. The reach id is according to the SWORD v16. mnt_FFSAR_Unconstrained River discharge estimates generated using the off-nadir FFSAR inputs and the SWOT-Confluence workflow under unconstrained conditions. mnt_FFSAR_Constrained River discharge estimates generated using the off-nadir FFSAR inputs and the SWOT-Confluence workflow under constrained conditions. [Notes]: Discharge folder (mnt_FFSAR_Unconstrained, mnt_FFSAR_Constrained) both contains discharge estimates produced by the GeoBAM, MetroMan, MOMMA, SIC4DVar, and Consensus methods. These datasets are intended to support validation, intercomparison, and further methodological development for off-nadir river discharge estimation.
