  1. Spaceborne Observations of the Polar Regions during IPY • The IPY provides an international framework for understanding high-latitude climate change and predicting world wide impacts. • Spaceborne technology offers unique capabilities for obtaining essential data for predictive models. • IPY era spaceborne instrumentation represents a technological leap beyond the capabilities of the IGY

  2. Global Inter-agency IPY Polar Snapshot Year (GIIPSY) GIIPSY aims to facilitate: • Use of current and soon to be launched earth observing satellites to develop broad spectral, medium and high resolution snapshots of the polar regions. • Use of the snapshots as gauges for assessing the impacts of past and future high latitude environmental changes. • Establishment of technical and programmatic infrastructure for sustaining international observations beyond IPY.

  3. GIIPSYScience Goals • Understand the polar ice sheets sufficiently to predict their contribution to global sea level rise • Understand sea ice sufficiently to predict its response to and influence on global climate change and biological processes • Measure how much water is stored as seasonal snow and its variability. • Understand glaciers and ice caps in the context of hydrologic and biologic systems and their contributions to global sea level rise. • Understand the interactions between the changing polar atmosphere and the changes in sea ice, glacial ice, snow extent, and surface melting. • Understand the spatial distribution of permafrost, its interactions with other systems or processes, and predict its response to climate change. • Improve understanding, observing and modeling capabilities of lake and river ice and its influence on energy, water and biochemical cycling, and aquatic ecosystems.

  5. The End to End System To include Svalbard and Antarctic Stations • IPY science goals can be realized through collaboration on the end-to-end system of: • Sensors and Spacecraft • Acquisition Planning • Receiving Ground Stations • Processing Facilities • Calibration and Validation • Historical data sets Additionally, plans should include suborbital campaigns where there may be a need to tie interrupted spaceborne observations (e.g. ERS-2 to IceSAT to Envisat RA2) that bracket the IPY period.

  6. New Technical Innovation The IPY is a scientific endeavour. Yet it is likely that the IPY investigations will also identify new technical requirements and approaches. A recommendation to the flight agencies is to seed the most promising ideas so as to prepare for next generation observations. GISMO/CReSIS: Build an instrument to image Greenland and Antarctica as they would appear were the ice sheets stripped away

  7. GIIPSY Strategy • Specify data requirements (IGOS, IPY-SCOBS) • Identify requirements satisfied through the routine operations (eg MODIS, MERIS) • For routine observations, work with flight agencies to assure that data are available/archived in standardized fashion • Identify requirements that can only be satisfied by non-routine tasking, processing and distribution (eg SAR, InSAR, high resolution optical). • Work with the flight agencies to acquire non-routine data so as to distribute the operational load. • Following selection of projects through the national A.O.’s, identify whether any legacy data sets are absent from the acquisition plans.

  8. GIIPSY Vision • Acquire key legacy data sets necessary to understand the changing polar environment. Examples include: • First, pole to coast measurement of Antarctic Ice Sheet surface velocity; • Annual, basin-scale measurements of Arctic sea ice motion; • First, circumpolar, fine resolution measurements of Antarctic sea ice kinematics • High spatial resolution measurements of polar glacier elevation; • Pan-Arctic view of lake and river ice break-up dynamics; • Infrastructure and programs for continuing observations into the future.

  9. GIIPSY Plans and Accomplishments • ESA IPY Data A.O. • CSA RADARSAT-1 archive access • U.S. NASA and NSF funds for ALOS processing • GIIPSY Data Requirements Document • GIIPSY meeting, 2006 Fall AGU • WMO sponsored meeting of international flight agencies, January, 2007
