Arctic Region Discharge Data

GRDC stations in the Arctic region.

GRDC currently holds river discharge time series from 2625 gauging stations in the Arctic region with earliest records from 1877 and an average time series length of 41 years, with a range from 1 to 138 years. Initially compiled for the ACSYS and CliC projects now the Arctic Region Dataset forms an integral part of the Global Runoff Database and is continually updated. Especially in the context of the Arctic-HYCOS project, the Arctic Region dataset is being expanded and updated to support the Arctic-HYCOS basic network.

Access to data follows GRDC’s data policy of free and unrestricted but identified access and is limited to non-commercial applications. Use the catalogues of stations in the Arctic to create your individual list of project stations for download via GRDC Data Portal.

The Arctic Region Discharge dataset was created to support ACSYS, CliC, and Arctic-HYCOS.

The name “ACSYS” designates both the Scientific Concept of the Arctic Climate System Study (ACSYS) within the World Climate Research Program (WCRP) and a program of the Joint Scientific Committee for WCRP. The program ACSYS ended in December 2003 and continues under the Climate and Cryosphere Program (CliC), which focuses on studying processes of how the cryosphere interacts with the other components of the climate system.
