Greenland Integrated Observing System
Greenland plays a unique and central role in the global climate system. The purpose of the Greenland Integrated Observing System (GIOS) is to resolve and understand the mechanisms behind climate and environmental change in Greenland and beyond. GIOS is a new coordinated network of sustainable long-term research infrastructures in and around Greenland observing the changing air, ice, land, and ocean conditions. GIOS is an important and timely national research infrastructure linking all institutions and universities currently carrying out Arctic research in the Danish Realm.

GIOS observing system
The ability to predict future changes are strongly dependent on concurrent and long-term records of glaciological, terrestrial, oceanic, and atmospheric processes. Arctic communities depend on knowledge especially at the ice sheet/ocean margins – where exchanges of heat, greenhouse gases, nutrients and freshwater are occurring. Sea level changes require monitoring of glaciers and ice sheets and have a global impact. In order to promote sustained data observations, we are developing a new and integrated system, the Greenland Integrated Observing System (GIOS).
Surface melting of the Greenland ice sheet is a major component of global sea level rise and is estimated using regional climate models, which are dependent on local observations for validation and calibration. This currently is dependent on data from a single site (Watson River in Kangerlussuaq) covered by PROMICE and dependent on seasonal manual installation and retrieval of instrumentation.
