Introduction

• International Polar Year - Space Task Group (IPY-STG) is a coordination success story

• Built a working interface between polar and cryospheric scientific community of practice and Space Agencies

• Enabled IPY coordination amongst Space Agencies• Allowed to fulfil IPY goals – and also key Recommendations

captured by former IGOS Partners Cryosphere Theme• Cryospheric science cuts across ocean, land, atmosphere physical

domains, and oceanographic, terrestrial, glaciological and science disciplines

• High-latitude polar, and 3rd pole cryospheric science is reliant upon on satellite remote sensing

• Desires coordinated use of R&D and operational satellite assets – via a coordinating body.

Mandate

• The Polar Space Task Group (PSTG) has been established under the auspices of the World Meteorological Organization’s (WMO) Executive Council Panel of Experts on Polar Observations Research and Services (EC-PORS).

• The group’s mandate is to provide coordination across space Agencies to facilitate acquisition and distribution of fundamental satellite datasets, and to contribute to or support development of specific derived products in support of cryospheric scientific research and applications

Why IPY Space Task Group?

• The IPY provided an international framework for understanding polar processes and high-latitude climate

• Spaceborne technology offered unique capabilities for obtaining essential data for predictive models

• During the recent IPY era, spaceborne instrumentation represented a technological leap beyond the capabilities of the previous IPYs (1882-83, 1932-33)

• Required coordination in order to optimize space agency contributions - to achieve IPY science objectives

Role of IPY - Space Task Group

• Established under mandate of WMO/ICSU Joint Committee for the International Polar Year (IPY) -

…to coordinate agency planning, processing and archiving of IPY Earth observation legacy data sets

• Satisfy science requirements in a fashion that distributes the acquisition and processing loads across agencies

• Identify a limited number of the most important scientific objectives achievable within the IPY time period and STG framework

• Invited participation from National and International Agencies: ASI, CSA, CMA, CNES, DLR, ESA, EUMETSAT, INPE, JAXA, NASA, NOAA, ROSHYDROMET, USGS, WMO, WCRP-CliC.

Re-establishedPolar Space Task Group (PSTG)

• PSTG established in 2011 under auspices of WMO Exec Council Panel of Experts on Polar Observations, Research and Services (EC-PORS)

• PSTG comprises members nominated by Heads of Space Agencies, upon invitation by WMO Secretary General;

• Objective is to contribute to, or provide support to, development of specific derived products required for cryospheric scientific research and applications;

• Actively seek realisation of benefits from the growing constellation of polar orbiting satellites, by mobilising the unique and complementary capabilities of each of the respective participating Agencies, in response to the Polar science priorities

• Secretariat provided by WMO

Recovery Glacier – TerraSAR-X

• Sea and glacial ice mass variability and contribution to sea level and ocean dynamics

• Glacial ice mass balance contribution to sea level• Polar atmospheric, ocean, cryosphere and terrestrial

products to facilitate improved weather, climate and environmental observation, monitoring and prediction

• Freshwater budget closure at high latitudes (snow and permafrost impact on polar hydrological cycle)

• Circumpolar changes in permafrost and terrestrial biosphere (consequences for Carbon and hydrological cycles)

• Physical and biological forcing of atmospheric chemistry in polar atmosphere

• Identifying new opportunities for integrated applications in response to emerging socio-economic issues of polar regions

Collaborative Approach for the PSTG

• Review and understand cryosphere and polar scientific requirements;

• Establish a balanced implementation strategy covering atmosphere, ocean and terrestrial domains;

• Develop a set of key strategic goals and translate them into observational requirements;

• Commitment to support data acquisition, and support for product development and establishment of relevant accompanying scientific studies, as appropriate for the Agency;

• Identify gaps in the existing observation capabilities and formulate recommendations for future satellite missions

Future Steps

• CEOS SIT: Establish communication link to CEOS and via WG Climate for reporting purposes

• Collect state of art and cryospheric science requirements and priorities via Workshops and interactions with representatives of Cryospheric science community

• Establish WGs (as required) for coordinating data acquisition activities

– SAR Coordination WG established• Establish Strategic Implementation Plan• Implement through annual meetings

and alignment of commitments taken through respective Agency programmes

• Periodic reporting to CEOS, CGMS, EC-PORS, CM

SAR Coordination WG

• Established to provide coordination across space agencies with SAR missions, to facilitate acquisition and distribution of fundamental SAR satellite datasets, and to contribute to or support development of specific derived products in support of cryospheric scientific research and applications.

• The membership of the SAR Coordination Working Group will be as inclusive as possible and will include:

– All SAR Operating Agencies (thematic experts and mission managers);– Other agencies - to ensure availability of complementary datasets, necessary ground

segment and contribution of thematic experts;– Members of the science community or scientific team leaders responsible for a specific

thematic requirement and who want to ensure that their collective needs are addressed;– Members of the “commercial arm” of SAR missions – under invitation by their public

counter-part.

Summary

• The multi-agency Polar Space Task Group is established on the foundation laid by the IPY Space Task Group

• In absence of any other similar coordinating body - PSTG has been re-established to continue to organise and coordinate future earth observing campaigns in support of Polar and Cryospheric science

• PSTG provides an essential link between the Polar Science communities and space agencies for articulating coherent, space-based data requirements in support of the operational implementation

• Facilitates more efficient use of space infrastructure in polar regions
