This dataset contains in situ observations of meltwater discharge through supraglacial stream networks and auxiliary data. Forty-six discrete discharge measurements and continuous water level measurements were collected for 62 days (13 June to 13 August) in 2016 for a 0.56 square kilometer supraglacial stream catchment in southwest Greenland. The dataset also contains water level observations in a cryoconite hole, shapefiles of the catchment boundary, gauging station location, and stream network. The dataset consists of the following files: Discharge_summary.csv : contains the 46 discrete discharge measurements (along with velocity and area) Discharge_profiles.csv : contains cross-sectional stream profiles of discharge for every 0.2 meters over the stream bed with reference to its deepest point Discharge_timeseries.csv : contains time series of stream water level and discharge with a 5-minute temporal resolution Cryoconite_hole_water_level.csv : contains time series of water level measured from a cryoconite hole with a 5-minute temporal resolution is shown Gauging_Station.zip : contains an ESRI shapefile with point data of the gauging station Stream_network.zip : contains an ESRI shapefile with the stream network Catchment_boundary.zip : contains an ESRI shapefile with the catchment boundary Please refer to the publication associated with this dataset for detailed uncertainty analysis and more information: Muthyala, R., Rennermalm, Å.
