Abstract

This resource includes a Jupyter notebook that offers a hands-on walkthrough for accessing, exploring, and analyzing global river discharge data derived from the SWOT (Surface Water and Ocean Topography) mission using the SWORD of Science (SoS) dataset. Using NASA's Earthdata earthaccess API and xarray, users learn how to search for and load SWOT SoS granules directly from the cloud without needing to download large files locally. The notebook guides users through identifying SWORD river reaches along a river of interest (e.g., the Rhine), visualizing reach centroid locations on an interactive map, and extracting reach-specific discharge time series from selected discharge algorithm outputs (e.g., HiVDI).
