Short summary
This study introduces CAMELS-FI (Catchment Attributes and MEteorology for Large-sample Studies-Finland), an extensive, consistent, high quality and easily usable hydro-meteorological dataset for 320 catchments in Finland. For each catchment, it includes daily streamflow data of up to 63 years (19612023) at the pour point of the catchment, daily catchment averaged meteorology for 14 variables for the full 63 years and 85 “static” attributes describing metadata of the stream gauges and the catchments, biogeophysical and societal attributes.
