3. CliC Goal and Objectives Principal Goal: Assess and quantify the impacts that climatic variability and change have on components of the cryosphere and the consequences of these impacts for the climate system, and to determine the stability of the global cryosphere Supporting Objectives: • Enhance the observation & monitoring of the cryosphere in support of process studies, model evaluation and change detection • Improve understanding of the physical processes and feedbacks through which the cryosphere interacts within the climate system • Improve the representation of cryospheric processes in models to reduce uncertainties in simulation of climate and predictions of climate change (role of the cryosphere on predictability of the climate system) • Facilitate assessment of changes in the cryosphere and their impact, and to use this information to aid in the detection of climate change

9. Where We Are • SCAR becomes a co-sponsor • MOA with IPA • ACSYS CD • Arctic Panel formed – Cecilie Mauritzen chair • GCOS – continued interaction to ensure cryosphere captured • GEO/GEOSS – input at national/international levels • IGOS-P Cryosphere – Jeff Key and OPP • WCRP COPES – how does CliC contribute? • Interactions with other groups – carbon, water, weather • ICSI – Commission on the Cryospheric Sciences • CliC/IGS/ICSI Symposium on Cryo as Indicator of Climate Change (2006) • ICARPII (November 2005) • International Polar Year – Ian Allison, Vladimir Kotlyakov • CliC 1st Science Conference (April 11-15 2005, Beijing)

10. CHALLENGES for CliC • CliC – cryosphere is gaining prominence –people care about snow and ice; it is in the media regularly; it affects people’s lives in northern communities; it affects economic development • We have a constituency or users broader than the scientific community – it is not just an academic exercise • To move forward: • WE NEED EVERYONE’S HELP AND CONTRIBUTIONS DURING THE YEAR • Secretariat and CIPO being run ragged • FUTURE: • White, bright, busy, challenging, engaging • To Succeed we need everyone’s ideas, help, suggestions and hard work

11. CRYSYS • NASA IDS Project • CSA Government Related Initiatives Program (GRIP) • “Cryospheric System in Canada” recompetedsuccessfullyin 2003as a NASA IDS project for next 3 years • highly rated in peer review • project is a sub-set of CRYSYS team members who responded to the call to participate in the NASA IDS. • CSA GRIP project “The Cryosphere and its Response to Climate Change” addresses IDS objectives and other ongoing CRYSYS research activities that address MSC and CSA objectives.

12. NASA IDS Project • How are global ecosystems changing? • Improved passive-microwave SWE mapping (Derksen, Goita, Walker) • Validation of EOS cryospheric products (Agnew, De Abreu, Derksen, Fernandes, Walker) • Integrated retrievals of sea ice type and thermodynamic state from AMSR-E (Barber) • Diurnal and seasonal snow covered sea ice process studies using surface and satellite based polarimetric microwave remote sensing data (Yackel) • Development and analysis of a long term land surface temperature database from spaceborne passive microwave data for the northern high latitude environment (Royer et al. ) • Development of approaches for monitoring river ice and frozen ground with SAR (Bernier et al.) • Monitoring glacier mass balance and glacier contributions to streamflow (Demuth - National Glacier Monitoring Programme, GSC/NWRI) • Monitoring permafrost temperature, active layer thickness, and permafrost sensitivity to warming (Smith – National Permafrost Monitoring Programme, GSC)

13. 2. How is global sea level affected by climate change? • Determining Canadian Arctic glacier contributions to sea level rise (Sharp) • Validation of CryoSat (Demuth and Sharp) • 3. How are variations in local weather, precipitation and water resources related to global climate variation? • Detailed evaluation of snow cover simulated by the Canadian Regional Climate Model (CRCM) for contrasting land surface types (Mackay and Derksen) • Examination of scaling issues in the representation of snow processes in CRCM (Derksen and Walker) • Assimilation of remotely sensed snowpack data into the WATCLASS coupled land surface process hydrological model (Fassnacht) • 4. What are the consequences of climate and sea level changes and increased human activities on coastal regions? • CRYSYS contributing (in advisory role) to GMES Northern View project which includes projects looking at the implications of changes in the near-shore ice complex (NIC) on shoreline erosion in the Gulf of St. Lawrence and the Beaufort Sea, and the development of an operational ice edge monitoring and forecasting product for use in northern communities.

14. 5. How well can long-term climate trends be assessed or predicted? • Evaluation of the representation of high latitude snow cover processes in climate models (Mackay and Marsh) • Modelling and validation of arctic snow distribution and melt at the local and meso-regional scales (Young and colleagues) • Merging of satellite and in situ data for assessing variability and change in SWE (Derksen and Walker) • Investigation of the role of the Arctic Oscillation and sea ice feedbacks in the Eastern Canadian Arctic and Beaufort Sea (LeDrew) • How well can cycling of carbon through the Earth system be modeled, and how reliable are predictions of future atmospheric concentrations of carbon dioxide and methane by these models? • Understanding the role of ice crusts and lenses on GHG emissions (Bernier) • BERMS

15. The proposed research activities contribute to several ESA initiatives related to the cryosphere (CryoSat and GMES), and to a number of international scientific projects (ArcticNet, ACSYS/CliC, BERMS, CALM, CASES, GEWEX, GCOS, GTN-P, GTN-G, MAGICS and SEARCH). • The CRYSYS project has made significant advances in the areas of data rescue/sharing and outreach over the period since 1999. The Canadian Cryospheric Information Network (CCIN) was established at the University of Waterloo in collaboration with the Canadian Space Agency and the private sector (www.ccin.ca). The ‘State of the Canadian Cryosphere” website (www.socc.ca) has continued to be developed as part of the CCIN to provide information and outreach. • We must integrate these initiatives and make sure we see the bigger picture and address the science questions that need to be answered to increase our knowledge of climate and cryosphere science to contribute to policy and socio-economic issues .

19. CRYSYS – the Future • Must continue to deliver new knowledge and information to meet its objectives as a cryosphere IDS team • Must continue to demonstrate the important contribution of satellite data to “cryosphere and climate change” in support of CSA, MSC and other national and international initiatives • CRYSYS transition to “CliC Canada” • CRYSYS is recognized internationally • Canada is seen as a key player in CliC • must build a strong partnership within the Canadian cryosphere community to contribute to CliC • Must get on with establishing a “CliC Canada/CRYSYS” structure to develop and implement Canada’s contribution to CliC

20. Thoughts for IGOS-P Cryosphere • What is the motivation for this effort? • Why is cryosphere important? • ACIA • It is not just cryosphere for climate – all applications • Not just remote sensing • Don’t forget in-situ networks • What are the cryosphere gaps – from all methods of observation • Antarctica? • Alpine regions of the world • Cryosphere is global • Data management • Links to GCOS, other IGOS-P, GEOSS- lot done (eg Canada) • Lot of reports on needs for obs have been prepared – let’s use them and not try to reinvent the wheel – update and expand • Solid precipitation, snow, sea-ice, freshwater ice, glaciers, ice caps and ice sheets, permafrost and frozen ground
