CAMELS-NZ: Hydrometeorological time series and landscape attributes for New Zealand

To support comparative hydrology and climate impact research, we present a large-sample dataset with hourly streamflow and hydrometeorological data from 369 catchments across Aotearoa New Zealand. It includes detailed catchment attributes and represents diverse hydrological regimes. This open-access resource enables model evaluation and international comparisons and helps fill a key regional gap in global hydrological data.
