Data, Monitoring & Forecasting
Good models need good data, and the tooling for finding, downloading and cleaning hydrological data has improved dramatically. This category collects data-access clients for national archives (USGS NWIS, NOAA, ERA5 and friends), time-series utilities built for hydrology, telemetry and monitoring stacks, and operational forecasting frameworks. If you have ever hand-downloaded gauge data from a web portal, the packages here will give you those hours back.
