1 Global Cryosphere Watch (GCW) WMO; Observing System Division (OSD) Miroslav Ondráš, OBS/OSD – Raymond Le Bris – ICG-WIGOS-4 19 January 2015 Geneva, Switzerland

2 The 16 th WMO Congress (2011) agreed that “WMO needs to have a focus on global cryosphere issues to be able to provide authoritative information to meet Members’ responsibilities on regional and global weather, climate, water and related environmental matters” and decided to embark on the development of the Global Cryosphere Watch (GCW), as an IPY Legacy, with a view of an operational GCW.

3 GCW Organization and Framework Mission: GCW will provide authoritative, clear, and useable data, information, and analyses on the past, current and future state of the cryosphere. WMO’s ability to support ongoing development and delivery of weather, climate, and water services contributes to ensuring the sustainable development and well being of nations. GCW will provide, directly or indirectly, data, information, products and analyses that will help Members and partners provide needed services to the wider user community.

4 1.Establish the core standardized surface-based observing network called CryoNet: 2.Identify Best Practices that will be applied by the two types of CryoNet sites. pes.htmlwww.globalcryospherewatch.org/cryonet/site_ty pes.html Immediate priority for GCW Scientific equipment on Antarctic Ice Sheet

5  CryoNet is one part of the whole GCW observing system, which is a component observing system of the WMO Integrated Global Observing System (WIGOS).  CryoNet covers all components of the cryosphere (glaciers, ice shelves, ice sheets, snow, permafrost, sea ice, river/lake ice) through an extensive approach of in-situ observations.  CryoNet is (initially) comprised of existing stations/sites, rather than creating new sites.  CryoNet is one part of the whole GCW observing system, which is a component observing system of the WMO Integrated Global Observing System (WIGOS).  CryoNet covers all components of the cryosphere (glaciers, ice shelves, ice sheets, snow, permafrost, sea ice, river/lake ice) through an extensive approach of in-situ observations.  CryoNet is (initially) comprised of existing stations/sites, rather than creating new sites. CryoNet – the core GCW Network

6 Two types of sites are envisioned based on the number of “spheres” that are monitored (e.g. atmosphere, biosphere, cryosphere, hydrosphere, etc.). Sites definitions

7 Typical CryoNet Integrated Site 7

8 CryoNet: Minimum Requirements for Inclusion

9 The process of selecting sites and stations as part of CryoNet is in its initial stage An online site application form - Site Questionnaire (metadata) - has been made available and several sites were identified for the pre-operational testing phase The whole process will be completed by December 2015 for consideration by EC-68. CryoNet Sites Selection

10 CryoNet Sites identified for the pre-operational testing phase CryoNet observations cover all components of the cryosphere through in situ observations (glaciers, ice shelves, ice sheets, snow, permafrost, sea ice, river/lake ice and solid precipitation). #Site Operating Country Location Integrated? 12 Morenas Coloradas Rockglacier Argentina no 24 Vuriloches Argentina no 25 Aonikenk Argentina no 3 Sonnblick Austria yes 8 Eureka Canada no 36 Valle Nevado Chile no 4 Qilianshan Station of Glaciology and Ecologic Environment China no 6 Qilian China yes 7 Tanggula Cryosphere and Environment Observation Station China no 20 Xidatan China yes 21 Tanggula China yes 27 Tianshan China no 29 The Koxkar Glacier Camp (KGC) China yes 2 PROMICE Greenland Ice Sheet Monitoring Network DenmarkGreenlandno 28 Zackenberg DenmarkGreenlandyes 10 Antisana 15 alfa Ecuador no 5 Sodankylä-Pallas Finland yes 33 Dome-C FranceAntarcticano …

11 Requirements and Capability for observations  GCW Requirements are being formulated and documented on the GCW website;  They will draw from various sets of existing user requirements and will be vetted by the scientific community;  Those requirements will become part of the WMO Rolling Review of Requirements (RRR);  Will be accessible through the Observing Systems Capability Analysis and Review Tool (OSCAR), the official source for WMO requirements, which has a cryosphere theme;  Need for a new application area “GCW”.

12 Measurement standards and practices

13 Step 1: Inventory of existing guidelines: Step 2: GCW works through these documents, engages the community, and reaches a consensus on best practices for each variable. Measurement Standards and Best Practices GCW is drawing on existing measurement methods where possible and where a scientific consensus has been or can be reached.

14 As a step toward in the development of the GCW best practices and the homogeneity of delivered observational data, a database of cryospheric terms as defined by existing glossaries has been compiled and is available through the GCW Website: Further work is needed to evaluate alternative definitions and converge on the official GCW Glossary that will be formally vetted and then translated into the UN languages. GCW Glossary

15 The design of the network is progressing in parallel with the establishment of the GCW Data Portal. It maintains metadata records and pointers to the data repositories physically holding the data. It also collects data to be provided to WIS according to user requirements. GCW Data Portal Provide the ability to exchange cryospheric data, metadata, information and analysis among a distributed network of providers and users. Data interoperability with established data centres such as NSIDC, WGMS, CryoClim and CCIN is being developed

16 Products and Services  Identification and development of initial products  Development of Hemispheric snow ”anomaly” trackers for SE & SWE  An inventory of snow datasets  Product intercomparison:  Snow intercomparison project ESA SnowPEX

17 GCW Website  About GCW – impact, framework  GCW News  Cryosphere now - products  CryoNet:  site requirements,  practices,  sites for pre-oper. phase  Activities – mtgs, projects  Outreach – forum, video  References – Glossary, acronyms, GCW documents
