Reproducibility Data for SWOT WSE Assimilation in the Ohio River Basin

This dataset supports the manuscript “Assimilation of SWOT water surface elevation enhances simulations of river dynamics in the Ohio River Basin.” It includes the study-specific LIS/HyMAP input file, metadata and HyMAP grid matches for the 66 USGS evaluation gages, and quality-controlled, preprocessed SWOT WSE observations in data-assimilation-ready format. The study covers the Ohio River Basin from December 2023 through April 2025 using a 0.1° HyMAP grid. MERRA-2 meteorological forcing and model outputs are not included.
