1. Coordination with GCOS and GEO – Cryosphere Observations Jeff Key NOAA/NESDIS (Agenda item 4.5)

2. Disappearing glaciers menace water supplies Inuit say spring in the Arctic is becoming more dangerous Polar bears could face extinction as global climate change warms the Arctic Tourism at risk Thawing permafrost, GHG emission and coastal erosion Floods feared as glaciers melt Melting Ice sheets, glaciers and global sea level rise Socio-economic Impacts Relevance to GEO SBAs:

3. The IGOS Cryosphere Theme developed the information (assessment of observational capabilities, requirements, and gaps) needed for a robust contribution to GCOS and GEOSS.

4. Accomplishments & Activities The IGOS Cryosphere Theme assessment resulted in improved coverage of cryospheric elements in the GCOS Implementation Plan and contributed to the GCOS-CEOS plan for satellite-based products. Began efforts to ensure an IPY legacy through the GEO Work Plan (AR-09-03b). Influenced the satellite mission planning process resulting in: –Approval of three orbital cycles of coordinated, experimental inter-satellite (ERS-SAR and Envisat ASAR) SAR interferometry. –Approval of the Global Monitoring for Environment and Security (GMES) Sentinel-1A C-band SAR mission. –Approval of the GMES Sentinel-3A SAR altimeter mission that will provide sea-ice thickness measurements. –Approval of RADARSAT MiniMAMM (Modified Antarctic Mapping Mission) SAR mapping of Antarctica. –Approval of CryoSat-2 with a re-launch in 2009. Developed new satellite products for real-time applications, e.g., sea ice concentration, thickness, and motion from MODIS. New acquisitions through GIIPSY. Contributed to the planning of ongoing SCAR scientific research projects (ISMASS, ASPeCT, PPE, and AGCS).  Fed directly into SAON (Sustaining Arctic Observing Networks) and the Arctic Council’s SWIPA project (Snow, Water, Ice, and Permafrost in the Arctic).  Inspired the WMO Global Cryosphere Watch. The community involvement in CryOS gave it the credibility needed for these accomplishments…the first time this has been done internationally for the cryosphere. The community that started with CliC and SCAR expanded through CryOS.

5. GEO Task AR-09-03b, “Legacy of the International Polar Year 2007-08” “Coordinate with the projects involved in the International Polar Year (IPY) to enhance the production and utilization of Earth observations in the realm of cryosphere. Advocate for an appropriate legacy for IPY projects and the continuation of relevant efforts beyond the duration of the IPY.” Area: Climate Relevant Committee: Architecture & Data Committee Point of Contact: WCRP

6. GEO Committee Interaction User Interface Committee: Participate in UIC meetings at least annually. Discussions revolve around communities of practice. Science and Technology Committee: Currently contributing to a STC report that will review the GEO Work Plan with respect to the integration of science activity and the integration of IGOS themes, and to identify underlying critical research needs.

7. The Cryosphere Community of Practice Weather prediction (NCEP, ECMWF,...) Weather forecast offices National ice centers (NIC, NAIS) River forecast centers Climate prediction centers GCOS, IASC, IPA, WMO, etc. Space agencies (NOAA, ESA, JAXA, …) National surface station operators Research scientists NSIDC, NCDC, WIS, … The cryosphere community was established through WCRP CliC and ICSU SCAR. It was expanded through the IGOS Cryosphere Theme, one of the last themes to be established. It is being expanded further through GCW and (potentially) GEO with increased emphasis on societal benefits.

8. The 15th WMO Congress (May 2007) welcomed the proposal of Canada that WMO will create a Global Cryosphere Watch which would be an important component of the IPY legacy. Congress requested the WMO Inter-commission Task Group on IPY to establish an ad-hoc expert group to explore the possibility of creation of such global system and prepare recommendations for its development. The Global Cryosphere Watch A legacy of IPY A component of WIGOS A legacy of WCRP/CliC in the area of observations A contribution to GEOSS

10. CliC and GCOS Interaction Recommendation from WOAP-3: WOAP recommends that CliC and the GCOS panels examine the list of cryosphere essential climate variables (ECVs) for completeness, and evaluate the compatibility of the GCOS and IGOS Cryosphere observational requirements for snow and ice. It is suggested that in the near term this be done in part through the revision of the GCOS Implementation Plan. In the longer term, the WMO Global Cryosphere Watch (GCW) should be the integrator of input and actions from the three GCOS panels. GCOS lists GCW as an implementation agent, so CliC interaction with GCOS will also be through GCW (if approved by WMO in 2011). GCOS Implementation Plan contains numerous actions relevant to CliC. CliC has submitted comments to the plan.
