Outline   WWW – a 50 year old role model WMO   Introducing WIGOS   Relationship with WWW   Vision   Integration   What and why   Who …. with an emphasis on Members and users

50 years of WWW: a role model for a future observing framework   International cooperation in collecting and exchanging world-wide meteorological observations   End to end connection across components of WWW (GOS, GTS, GDPFS)   Strongly user driven, from requirements to service delivery   Integration – space and in situ, system design, observe once-use many times, numerical models   Think global, act local

WIGOS: A future observing framework for WMO World Weather Watch GOS



GCOS Partners





What is WIGOS?   An over-arching framework for the coordination and evolution of WMO observing systems and the contributions of WMO to co-sponsored observing systems.   A WMO priority   With WIS, a WMO contribution to GEOSS.   WIGOS is not:   Replacing or taking-over the existing observing systems, which will continue to be 'owned' and operated by a diverse array of organizations, programmes and, importantly, Members.

WIGOS Vision   Coordinated, comprehensive, reliable and trusted observations for WMO   Addressing, in a cost-effective and sustained manner, the evolving observing requirements of Members in delivering their weather, climate, water and related environmental services.   Enhanced coordination of WMO observing systems with those of partner organizations for the benefit of society.   WIGOS will build on the WWW 'role model'

To achieve the WIGOS Vision….   WIGOS will implement a framework for enabling the integration, interoperability, optimized evolution and best-practice operation for   WMO observing systems, and   WMO’s contribution to co-sponsored systems.   WIGOS will use and exploit the WMO Information System (WIS)   To allow continuous and reliable access to an expanded set of environmental data and products, and associated metadata

What do we mean by integration?      

Composite systems 'Network of networks’ Integration through:                


Supporting diverse user needs Systems designed for efficiency & effectiveness NWP data assimilation Partnership & collaboration End-to-end service model Data policy, access and exchange Coordinated network operation & maintenance Practices and procedures

Integration is NOT one-sizefits-all

What do we mean by interoperability?   Ability to access, combine or compare observations from one source or system with those from another   To achieve this, need:   Metadata   Standards   Regulatory material

  Interoperability is key to turning observations into effective data, products and services that meet real user needs

WIGOS will…   Result in increased information flow and knowledge, improved efficiency and enhanced services across all WMO Programmes.   Support and sustain the delivery of the other four priorities, especially:   Global Framework for Climate Services   Disaster Risk Reduction   Capacity Development   Support Members and deliver benefits at global, regional and national levels, but requires commitment at all those levels

WIGOS Framework: Key activity areas Management of WIGOS Implementation

Collaboration with cosponsors and partners

Observing system operation & maintenance

To plan, implement and evolve WIGOS component systems

Data discovery, delivery & archival

To ensure supply of and access to WIGOS observations

To oversee, guide and coordinate WIGOS Design, planning and optimised evolution

Capacity Development

To facilitate and support the operation of WIGOS Communications and outreach

Operational Information Resource

Standards, interoperability & compatibility

Quality Management

Why WIGOS – and why now?   Global environmental change agenda   Increased awareness of need to act   Value of evidence-based decision making   Scientific and technical advances   Numerical modelling and data assimilation   Greater capacity to access and use observations in decision making   Response to climate and natural disasters   Multi-sector, multi-hazard and multi-disciplinary   Ongoing resource pressures and accountability

In conclusion…   At its simplest, the WIGOS framework is about:   Documenting and implementing best practice in making and sharing observations   Coordination and collaboration for efficiency and effectiveness   Integration and interoperability in all senses   Delivering observations that meet user needs in a way they can use them   Empowering WMO and especially NMHSs   to assume a national leadership role and   to better serve their communities
