Item 4.2
WIGOS Information Resource (WIR) andObserving System Capability Analysis and Review tool
(OSCAR)
Etienne Charpentier (WMO/OSD)Joerg Klausen (MeteoSwiss)
WMO; Name of Department (ND)
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
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
www.wmo.int/sort (TBD) The Observing System Capability Analysis and Review Tool (OSCAR)
www.wmo.int/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.
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)
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/)
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!
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
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

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
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

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
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
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!
