Standing Groups address scientific problems of the cryosphere that require medium- to long-term reflection. Standing Groups shall have well considered aims, objectives, milestones and deliverables. They should be international in composition. Standing Group activities could include, for example,monitoring, databasing, and dissemination of cryospheric information. Standing Groups will normally have a life-time of at least eight years. They may be renewed, with suitable justification, for further periods of eight years. Standing Groups report annually to the Bureau through the appropriate IACS Vice-President or other Bureau member and may also be subject to external expert evaluation at appropriate intervals.
