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

2 WIGOS Information Resource (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   The « Standardization of Observations » Reference Tool (SORT)  Referencing WIGOS related standards and best practices into a database for easy search and access to specific documents and/or sections of documents  (TBD)  The Observing System Capability Analysis and Review Tool (OSCAR)   A tool for the WMO Rolling Review of Requirements providing information on (i) observational user requirements, (ii) space-based observing system capabilities, and (iii) surface-based observing system capabilities. Includes a critical review module to compare requirements with capabilities.

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

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 -

7 Status of SORT  Consultant recruited  Technical specifications defined  Simple taxonomy proposed  Using vocabularies and indexing words  International Meteorological Vocabulary (IMV)IMV  BIPM International Vocabulary of Metrology (VIM)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/)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 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 10

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

14 Table 2: WMO responsibility and proposed reporting mechanisms for the OSCAR project development Role and responsibilityReporting to to collaborate with MeteoSwiss in further specifying the project goals & functional requirements of OSCAR (lead: WMO) IPET-WIFI to provide human resources, including project lead and requirements engineer, in support of the project WMO Secretariat to establish the necessary conditions and WMO-internal support for the migration of the “Requirements”, “Space” and “Vol A” components of OSCAR to MeteoSwiss IPET-WIFI to establish agreements with the data owners and/or operators of external data sources regarding operational delivery of metadata needed for OSCAR IPET-WIFI to inform MeteoSwiss on milestones achieved and major deviations from the project plan WMO Secretariat

15 Table 3: WMO responsibility and proposed reporting mechanisms for the long term maintenance and operations of OSCAR Role and responsibilityReporting to to seek contributions from WMO Members to the WIGOS TF for OSCAR ICG-WIGOS to establish a line item into the WIGOS TF for the operations, maintenance & evolution of OSCAR ICG-WIGOS to contribute financially to cost of operating, maintaining, and evolving OSCAR through a contract to be established with MeteoSwiss in due course WMO Secretariat to maintain OSCAR content & provide human resources for quality monitoring of the system, coordination with Members contributing information to the system, reporting, and liaison with MeteoSwiss IPET-WIFI in consultation with IPET-OSDE to ensure the cooperation of the external (machine-to-machine) data providers WMO Secretariat to propose future evolutions of the systemIPET-WIFI to inform MeteoSwiss on any issues concerning this collaborationWMO Secretariat

20 WIGOS Metadata and OSCAR (I)  WIGOS metadata are compiled to allow adequate use of observational data  focus on data application  Metadata in OSCAR are collected to support the RRR process  focus on network design  The WIGOS RRR process consists of comparing technology-free requirements with observational capabilities  Attributes in the «OSCAR/Requirements» database determine the minimal requirements for the «OSCAR/Capabilities» database

21 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

22 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!
