2. SUMMARY WMO Priorities Global Cryosphere Watch
Rolling Review of Requirements
Opportunities for collaboration GCW-SAON

3. WMO Priorities 2016-2019 Disaster Risk Reduction
Global Framework for Climate Services
WMO Integrated Global Observing System
Aviation Meteorological Services
Polar and High-mountain Regions:
Improve meteorological and hydrological monitoring, prediction and services, by:
(i) operationalizing the Global Cryosphere Watch;
(ii) understanding the implications of changes on the global weather and climate patterns
Capacity Development
WMO Governance
Align the WMO priority activities with emerging global needs, including the needs regarding the meeting of

4. GCW Activities (what is GCW doing, or what’s happening that wouldn’t otherwise happen)
Fundamental contribution to GEOSS;
refining cryosphere observational requirements for WIGOS OSCAR ;
network of surface observations, with "CryoNet“ at its core;
collating/establishing measurement guidelines and best practices;
engaging in and supporting intercomparisons of instruments and (satellite) products, e.g., GCW Snow Watch(and SnowPEx); SPICE
enable access to data and metadata through GCW portal;
Use the WMO data regulatory framework to enable the development and implementation of data/metadata standards
contributing to WMO’s space-based capabilities database (with PSTG);
producing unique hemispheric products, e.g., “snow anomaly trackers”;
engaging in historical data rescue (e.g., snow depth);
building a glossary of cryospheric terms;

5. CryoNet network of cryospheric in-situ observations.
extensive monitoring through GCW (standardized) practices;
cryospheric data for improved process understanding and modelling;
calibration and validation data
for satellite data;
linking cryospheric ground truth observations
to cryospheric models;
training.
CryoNet

6. WMO Rolling Review of Requirements
Review of technology free requirements for observations within each area of application
Review of observing capabilities (existing, planned) of observing systems (surface, space based)
Critical review of the extent to which the technology deliver the requirements
Statement of Guidance:
Inform on the extent to which the requirements are met by the identified systems
Informs the dialogue with the observing system developing agencies, influencing future research
Feasibility and affordability

7. Application Areas GCW is an evolving area:
Global NWP;
High resolution NWP;
Nowcasting and very short range forecasting;
Subseasonal to longer term prediction;
Forecasting atmospheric composition;
Monitoring atmospheric composition;
Provide atmospheric composition information to support services in urban and populated areas;
Aeronautical meteorology;
Ocean applications;
Agriculture meteorology;
Hydrology;
Climate monitoring;
Climate applications;
Space weather
GCW is an evolving area:
requirements under development

8. RRR Process http://www.wmo-sat.info/oscar/
Requirements defined in terms of:
Horizontal and vertical resolution
Frequency of observations
Timeliness (delay in availability)
Uncertainty (acceptable RMS errors, limitations or bias)
Values:
goal,
threshold,
breakthrough.
WMO
collects requirements for observations
Catalogues the current and planned provisions of observations
Generates a database on User Requirements and Observing System Capabilities
Accessible via WMO website through the Observing Systems Capabilities Analysis and Review Tool (OSCAR).

10. Cryosphere variables
CryoNet Team meeting, Sept 20-22,
Recommended and desirable variables by component
Next steps: complete the assessment of attributes of variables

11. gcw.met.no GCW DATA PORTAL Engagement with Arctic Data Committee
Exchange cryosphere data, metadata, information and analyses among a distributed network of providers and users.
The GCW Data Portal is part of WIS,
a Data Collection and Production Centre
and is interoperable with data centres.
YOPP data management builds on GCW data management

12. GCW Steering Group Meeting: Jan 16-19, 2017, Cambridge, UK
Focus on implementation: potential for collaboration with CON SAON
Define GCW as a Programme
Data Exchange
Partnerships
New products
Expansion of the GCW Observing Network

13. Global Precipitation Climatology Centre
GCW partners:
Collaboration and cooperation with partners is essential to successfully conduct GCW activities at the international, regional and national levels. Partners include, but not limited to:
Global Precipitation Climatology Centre
