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) 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)
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. OSCAR complexity and effort vs. other WIR components
Web Portal, Basic Information
OSCAR
SORT
As we are talking a lot about individual modules such as SORT and the web portal, just to stress that OSCAR is really the “meat” of the WIR and will require most of the work
OSCAR has already been partly development, namely Space and Requirements modules 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 (

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

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!
