Transcript IPY Introduction (M. Drinkwater) - Byrd Polar and Climate Research

International Polar Year (IPY): STG
• The polar regions are symbolic, providing demonstrable
evidence of human fingerprint on climate change
processes
– High-lat. climate change has a broad range of physical, biogeochemical, and socio-economic impacts (e.g. IPCC 4th AR;
Stern Report etc)
– impacts lie at heart of the scientific basis and justification for
polar-orbiting satellites
• IPY provides a unique opportunity to Space Agencies:
– already federates over 60 nations in high-latitude research
– Comprehensively planned in-situ, airborne and satellite-borne
experiments
• No better opportunity to establish framework for
delivering a coordinated satellite legacy dataset
– All-time peak in terms of number of relevant polar-orbiters?

IPY Spaceborne Observations of the Polar Regions
• The IPY provides an international framework for
understanding high-latitude climate change and
predicting global impacts.
• IPY-era satellite capabilities represent a technological
leap far beyond the capabilities of the IGY
• Spaceborne technology offers unique capabilities for
obtaining essential data for predictive models.
• Coordinated spaceborne observations during IPY can
serve as a prototype for coordinated international
ventures such as:
– IGOS-Partners Cryosphere Observing System (Cry-OS)
– Global Climate Observing System (GCOS) – by fulfilling
observations of Essential Climate Variables
– GEOSS - IPY Legacy Dataset (Action Item CL-06-05: Ref
GEO Work Plan)
Meeting Goals
• For Flight Agencies to take ownership of IPY Legacy
Objectives, and elements of the IPY “Polar Snapshot”
• To allow Agencies to develop insight into how/where
they can deliver a unique contribution to IPY legacy
• To establish commitment to IPY-STG planning exercise
• For Flight Agencies to take appropriate steps towards
taking commitment to meet specific scientific objectives
• For Agencies to actively plan and coordinate IPY
acquisitions to fulfil goal of an IPY data legacy
• To schedule future meetings of IPY-STG for review of
acquisition plans and planning
• For Agencies to speak with a coordinated single voice
in support of realising the IPY goals and objectives
Proposed Meeting Foci
• Focus on issues governing planning/acquisition of
datasets which will otherwise not be accessible without
immediate planning (March 2007 IPY kick off!)
• Work on issues that act as roadblocks to the STG in
preparation for acquisition of the IPY snapshot dataset
– coordinated mission planning
– interoperability of data management systems/archives
• Establish Actions and Recommendations that help
facilitate a coordinated Interagency “snapshot”
• Establish Actions and Recommendations that feed into
the work of existing bodies such as SCOBS & CEOS
SIT (or National Agencies) to help with implementation
or realisation of the scientific benefits of the data
