  2. Design, planning and optimized evolution of WIGOS component observing systems • WIGOS Framework Implementation Plan (WIP) KAA#3 • WIP addresses overarching framework for integration of observing systems • EGOS-IP addresses evolution of WIGOS component observing systems • Activity under responsibility of IPET-OSDE • Coordinating undertaking of Rolling Review of Requirements, inc. Vision for the GOS, and Implementation Plan for the Evolution of Global Observing Systems (EGOS-IP) • Impact studies • Monitoring progress on EGOS-IP (through NFPs) • Defining principles for observing system network design • CBS support to WIGOS, GFCS, GCW

  3. WMO Rolling Review of Requirements (RRR)http://www.wmo.int/egos • Addressing the requirements for all WMO applications • Commission for Basic Systems (CBS) in charge of RRR • Inter Programme Expert Team on the Observing System Design and Evolution (IPET-OSDE) • Databases managed by WMO Space Programme • User requirements for observations • Observing system capabilities

  4. Application areas in RRR • Global Numerical Weather Prediction (NWP) • High Resolution NWP (HRNWP) • Nowcasting and Very Short Range Forecasting (NVSRF) • Seasonal to Inter-annual Forecasts (SIAF) • Aeronautical Meteorology (CAeM) • Atmospheric Chemistry (CAS) • Ocean Applications (JCOMM) • Agricultural Meteorology (CAgM) • Hydrology (CHy) • Climate Monitoring (GCOS) • Climate Applications (other aspects – CCl) • Space Weather • Cross cutting (or under discussion) • Global Cryosphere Watch (GCW) • Global Framework for Climate Services (GFCS) • Obsolete: Synoptic Meteorology (merged into Nowcasting & VSRF)

  5. Rolling Review of Requirements (RRR) and Evolution of Global Observing Systems Long term vision of global observing systems Application Areas Critical review User requirements Statements of Guidance (gap analysis) Priorities, cost effectiveness Impact Studies Observing Systems Capabilities (OSCAR) Implementation Plan (EGOS-IP) Members’ and Space Agencies Observation Programmes

  6. The RRR • Observing Systems Capability Analysis and Review tool (OSCAR) • OSCAR/Requirements: Technology free user requirements • Observing systems capabilities • OSCAR/Space: Space-based capabilities • OSCAR/Surface (under development): Surface-based capabilities • Critical review – inputs: • Comparisons of URs with capabilities • Results from impact studies • Analysis by experts • Statements of Guidance (SoGs) = gap analyses • SoG for each application area reviewed by IPET-OSDE • Feeds into Vision of the GOS and EGOS Implementation Plan • EGOS-IP responding to the Vision of the GOS in 2025 approved by CBS-15 and EC-65

  7. How user requirements are specified • For each application & each geophysical variable • Horizontal resolution • Vertical resolution • Accuracy • Observing cycle • Timeliness (Delay) • For each parameter • “min” (or threshold) : value below which observations are worthless • “max” (or goal) : value beyond which improvement gives no additional value • “breakthrough” : proposed target for significant progress

  23. Users of the WIR (audience) • Members • Regional Associations • Technical Commissions & experts • Data users (internal & external to WMO) • Obs. network managers & implementers • Partners • All use information from the WIR • All contribute information to the WIR

  24. Role of Members, RAs, TCs • Members & RAs • Compilation of national & regional requirements • Assist for the collection of information on national & regional capabilities • Use the WIR tools for national & regional network design & planning • Technical Commissions • Technical advise (e.g. IPET-OSDE on OSCAR requirements) • Compilation and validation of global requirements (application area focal points) • Assist for the collection of information on specific observing systems capabilities (e.g. GAWSIS, WHYCOS, JCOMMOPS)

  25. WIR Tools 1/2 • “Standardization of Observations” Reference Tool (SORT) • Allows network supervisors, managers, operators, and data users to easily access information on relevant WIGOS Regulatory Materials, incl. standards • Experts to better apprehend standards, identify inconsistencies, and propose solutions • Goals are to • Optimize operational & development costs • Support production of coherent, traceable, documented data-sets • Improve data quality, and measurement uncertainty • Enhance data usability • Harmonize standards & enhance interoperability

  26. WIR Tools 2/2 • Observing System Analysis and Review Tool (OSCAR) • http://www.wmo.int/oscar • Used by the Rolling Review of Requirements (RRR) for the analysis, design and planning of WIGOS, allowing comparison of observational user requirements with actual or planned capabilities (critical review) • One-stop shop access to satellite, instrument, and ground-based network metadata • A tool for developing countries (avoiding having to develop their own database nationally) • Components of OSCAR • OSCAR/Requirements (observational user requirements) • 12 Application Areas • > 200 variables • OSCAR/Space (space capabilities and tools) • OSCAR/Surface (basic/core metadata of surface-based obs. systems) • OSCAR/Distributed (complete metadata sets made accessible by Members & partners)
