GCW Framework

GCW’s organizational, programmatic, procedural governance is based on WMO structures and interfaced with those of partner organizations. An initial framework, or conceptual model, for GCW is shown below. It illustrates the “why, what, and how” of GCW operation.

The GCW Steering Group (GSG) and Working Groups (WG) are central to GCW operations. The GCW Steering Group provides high-level guidance on GCW development and implementation and steers the activities of its Working Groups. The GSG currently reports to the WMO Executive Council through the Panel of Experts on Polar Observations, Research and Services (EC-PORS) and provides recommendations for GCW development and implementation for consideration by the WMO Executive Council and the WMO Congress. Working Groups and their Teams are responsible for implementing the GCW tasks.

GCW data include basic measurements and higher-level products. The GCW Portal (http://gcw.met.no) is a web interface that contains information about datasets (metadata), but not necessarily the data themselves. Instead, it links to data that are stored at partner data centres and therefore functions as a catalogue. It is WIS compatible and will become a WIS Data Collection and Production Centre (DCPC) to allow for ingesting the available data into GTS/WIS. Information and analysis products will be derived from surface and satellite observations, operational products, reanalyses, and research datasets.

Collaboration and cooperation through partnership is essential. Cryospheric data, information, products and knowledge is provided not only from National Meteorological and Hydrological Services (NMHSs), but also from national and international partner organizations, agencies, and the scientific community. National weather and ice services, space agencies, and research groups are critical to the development, implementation and success of GCW. They not only provide the basic observations for GCW, but also contribute the development of measurement practices, observational requirements, and product selection.
