Hydrometeorological dataset (2014–2019) from the high Arctic unglaciated catchment Fuglebekken (Svalbard)

A hydrometeorological dataset of the unglaciated Fuglebekken catchment (SW Spitsbergen) is provided. The time series includes air temperature, precipitation, potential evapotranspiration, and runoff data from 2014 to 2019 in three time steps (6 h, 12h, and 24 h). Meteorological data comes from the Hornsund meteorological station (WMO 01003). Runoff was measured using a portable flowmeter Nivus PCM-F with Active Doppler sensor at the bottom of the Fuglebekken stream in each hydrological active season. Provided variables are essential to the recognition of the functioning of Arctic catchments. In particular, this dataset can be used to understand water circulation in the catchment as input data to multiple hydrological models.
