Greenland Climate Network (GC-Net)

Starting with a single station in 1991, the Greenland Climate Network (commonly known as GC-Net) is a set of Automatic Weather Stations (AWS) set up and managed by the late Prof. Dr. Konrad (Koni) Steffen, and spanning the Greenland Ice Sheet. This first station was "Swiss Camp" or the "ETH-CU" camp which was used as a field science and education site by Koni for years. The GC-Net was expanded with multiple NASA, NOAA and NSF grants throughout the years, and then supported by the Swiss Federal Institute for Forest Snow and Landscape Research (WSL) in the later years.

GC-Net data, previously hosted by CIRES, have now been moved to WSL’s Envidat data repository:

The dataset is undergoing further reprocessing and the latest quality-checked version of the data can be found at The near-real-time transmitted data from active stations can be accessed at

The Geological Survey of Denmark and Greenland (GEUS) in Copenhagen, has been appointed to the continuation of climate monitoring at the GC-Net sites ( The new GC-Net data will be distributed through the PROMICE website (
