  1. TT-WMD-2(Geneva, 12-15 May 2014)Item 4.2WIGOS Information Resource (WIR) andObserving System Capability Analysis and Review tool (OSCAR)Etienne Charpentier (WMO/OSD)Joerg Klausen (MeteoSwiss) WMO; Name of Department (ND)

  2. WIGOS Information Resource (WIR)www.wmo.int/wigos/wir Goal: Provide single access point for WIGOS stakeholders (Network decision makers, Implementation Coordinators, Data users etc.) Shall contain all relevant information on the status and evolution of WIGOS and its components Formally launched at EC-65 (May 2013) To be fully operational from 2015

  3. The WIR Components • The Portal • www.wmo.int/wigos/wir • The « Standardization of Observations » Reference Tool (SORT) • ReferencingWIGOS related standards and best practices into a database for easysearch and access to specific documents and/or sections of documents • www.wmo.int/sort(TBD) • The Observing System CapabilityAnalysis and ReviewTool (OSCAR) • www.wmo.int/oscar • A tool for the WMO Rolling Review of Requirements providing information on (i) observational user requirements, (ii) space-basedobserving system capabilities, and (iii) surface-basedobserving system capabilities. Includes a criticalreview module to compare requirementswithcapabilities.

  4. OSCAR complexity and effort vs. other WIR components Web Portal, Basic Information OSCAR SORT 4

  5. Status of the Portal • Most pages developed • Missing pages/parts • Information on Standardization, System Interoperability, and Data Compatibility • Information on Data Discovery, Delivery and Archival • Status of WIGOS implementation • In Regions • By Technical Commissions • By Members • Link to OSCAR/Surface (once developed) • Link to SORT (once developed)

  6. The WIR web portal - www.wmo.int/wigos/wir

  7. Status of SORT • Consultant recruited • Technical specifications defined • Simple taxonomy proposed • Using vocabularies and indexing words • International Meteorological Vocabulary (IMV) • BIPM International Vocabulary of Metrology (VIM) • Issues • Managing both documents (standards) content and metadata • Limited number of standards referenced in SORT initially (WMO No. 49, 8 , 544, 488, 558, 571) (see annex 3 of doc.) • Later: WIGOS Manual & Guide, GAW, regional & national best practices • Technical options under investigation • e.g. using Typéfi (http://www.typefi.com/)

  8. Status of OSCAR • OSCAR/Requirements operational at WMO since 2011 • Further developments made in 2013 • OSCAR/Space operational at WMO since Sept. 2012 • Complete overhaul of Earth Obs. Instrument assessments performed in 2013 • Initial assessment of > 200 space weather instruments in 2013 • Both components hosted by private operator • OSCAR is a tangible and visible success of WIGOS • OSCAR/Space is very popular (>150 visits / day) • Success of current OSCAR largely due to the WMO Space Programme Office, and to Nils Hettich (German JPO) in particular. • Nils left WMO Secretariat for another position, but we are grateful for his contributions, and to Germany!

  9. Future Operations of OSCAR • OSCAR needs an operational environment for operations and further development. • Partnership with MeteoSwiss (MoU) for OSCAR platform • Content management with WMO • Operations with MeteoSwiss • Funding from WMO RB & MeteoSwiss/Switzerland & Voluntary Contributions (WIGOS trust fund) • MeteoSwiss also in charge of developing and operating the new version of GAWSIS. • Excellent opportunity to integrate both systems

  10. Migration of OSCAR to MeteoSwiss • Phase I (by 2015): • Develop OSCAR/Surface with basic observing network types and include it in the MeteoSwiss IT infrastructure • Continue to evolve OSCAR/Requirements and OSCAR/Space in parallel at WMO • Adapt OSCAR/Requirements to MeteoSwiss IT infrastructure • Jointly develop critical review module • Phase II (by 2017): • Adapt OSCAR/Space to MeteoSwiss IT infrastructure • Complement OSCAR/Surface with missing observing network types (Annex 1 of doc.) • Integrate Space and Surface into the critical review module test footer

  11. Some points worth noting on OSCAR (1/2) • OSCAR will continue to be operated from the WMO Secretariat during migration process • OSCAR/Requirements needs to be further promoted as unique repository of observational user requirements from WMO • User Requirements for some application areas are incomplete (e.g. Agromet., Hydrology, Aeromet., GAW) • ET-EGOS & IPET-OSDE recommendations to be taken into account

  12. Some points worth noting on OSCAR (2/2) • ICG-WIGOS agreed that OSCAR should be repository of a sub-set of WIGOS metadata, and particularly • Metadata required for observing systems capabilities for RRR critical review module • Metadata required for operational use (evolution of Vol. A) • Other metadata to be collected, maintained and archived by Members • TT-WMD to clarify (i.e. detail) what metadata to be included in OSCAR and what metadata to be mandatory (see Appendix D for proposal) • OSCAR Leadership discussed & agreed at IPET-OSDE, IPET-WIFI, ICT-IOS (ICG-WIGOS to eventually decide) • Technical specifications of OSCAR to be coordinated by IPET-WIFI in close liaison with the Secretariat during requirements engineering phase • OSCAR aspects to be included in the workplans of the OPAG-IOS Expert Teams, in particular with regard to OSCAR content quality

  13. Table 1: Proposed split of responsibility within WMO for the management of OSCAR [1] ET-SUP and IPET-OSDE have a role of reviewing OSCAR content proposed by ET-SAT [2] if necessary, the ET-ABO will consult with the CIMO TT on Aircraft Based Observations (TT-ABO)

  14. Table 2: WMO responsibility and proposed reporting mechanisms for the OSCAR project development

  15. Table 3: WMO responsibility and proposed reporting mechanisms for the long term maintenance and operations of OSCAR

  18. WIGOS Metadata and OSCAR (I) • WIGOS metadata are compiled to allowadequate use of observational data  focus on data application • Metadata in OSCAR are collectedto support the RRR process focus on network design • The WIGOS RRR processconsists of comparingtechnology-free requirementswithobservationalcapabilities Attributes in the «OSCAR/Requirements» databasedetermine the minimal requirements for the «OSCAR/Capabilities» database

  19. Scope of “OSCAR/Requirements” Database • Requirements are specified for 4-dimensional tuples • Geophysical variable  Accumulated precipitation (over 24 h) • Vertical layer  near surface • Application area  Climate-AOPC • Coverage (type)  Global • Requirements are expressed with 6 criteria • [required] horizontal resolution,  {100 | 200 | 500} km • [required] vertical resolution,  n/a • [required] observing cycle,  {12 | 16 | 24} h • [required] timeliness,  {1 | 3 | 12} d • [required] uncertainty, and  {1.0 | 1.3 | 2.0} mm • [required] stability (1/decade)  not specified

  20. WIGOS Metadata and OSCAR (I) Element needed for OSCAR and present in standard • Element needed for OSCAR and can be deduced from elements in standard • Vertical layer (from spatial extent of observation) • Coverage (from spatial extent of observation) • Element needed for OSCAR and not in standard • None!
