SWOT_WSE_profiles.ipynb

This Python script visualizes and compares water surface elevation (WSE) profiles derived from the SWOT mission across multiple acquisition dates and highlights the location of a known landslide. The script includes uncertainty bands (±RMSE) for each data source, allowing for visual inspection of measurement precision. Documented in: README.md
