 The Hydrological Analysis Toolkit (HAT) is a software suite for hydrologists working with simulated and observed river discharge. HAT performs data analysis on hydrological datasets, with its main features being:
 - mapping station locations into hydrological model grids
-- extraction of timeseries at station locations from gridded model outputs
-- statistical analysis of hydrological timeseries
+- interactive visualizations

+> [!NOTE]
+> The station extraction and hydrostats functionality formerly in HAT now live in [ecmwf/hyve](https://github.com/ecmwf/hyve).
