Coordinated satellite observations during the IPY: Towards achieving a polar constellation

Abstract

Summary The Global Interagency IPY Polar Snapshot Year (GIIPSY), the World Meteorological Organization (WMO) Space Task Group (STG) for the International Polar Year (IPY), and the Integrated Global Observing Strategy Cryosphere Theme are related projects involved in the implementation of recommendations for spaceborne observations during the IPY. Science requirements are being compiled by GIIPSY and IGOS Cryosphere, which are also seeking to identify ways in which the resources of space-faring countries can be used to achieve the scientific objectives without putting undue burden on any single organization. The STG brings together space agencies from around the world to coordinate their IPY activities. Thus far, the space agencies have worked to develop IPY data ‘portfolios’ that, in total, aim to satisfy a significant number of scientific requirements. The data legacy and the experience gained in developing scientific consensus and space agency collaborations will provide a strong foundation for the continued observations planned through IGOS Cryosphere. This paper discusses the progress made by GIIPSY, STG and IGOS Cryosphere entities in coordinating international efforts to collect spaceborne ‘snapshots’ of the polar regions during the IPY, and in establishing a preliminary structure for sustaining observations into the future.
