The dataset contains measurements of river stage and discharge for one sites along the Akuliarusiarsuup Kuua River's northern tributary, with 30 minute temporal resolution between June 2008 and December 2016. This river is a tributary to the Watson River discharging into Kangerlussuaq Fjord by the town of Kangerlussuaq, Southwest Greenland. Additional data of water temperature is also provided.

Compared to version 1.0 of the dataset, this dataset used a total of 36 in situ discharge observations collected between 2008 and 2012 to construct the rating curve. The discharge estimates have an average uncertainty of 22.7%. Compared to version 1.0 and 2.0, time series gaps due to sensor service (<3 hr) have been interpolated, and sensor drift in water level and temperature has been corrected.Funding for this data set was provided by NASA Cryospheric Sciences Program grant NNX14AH93G
