Why me?
• Member of vGISC ITT Drafting Teams– (current and previous)
• WMO Regional Association VI Co-Rapporteur for Information Systems & Services – (with Leonid Bezruk, Russia)
• WMO Focal Point for RTH Exeter
• I have been around for a long time– (and partly to blame for GRIB, BUFR, & CREX)

Collaboration agreement for new ITT prepared by UKMO
2009-01: Started working
– Backup workshop
– Open source software (Geonetwork, Open SSO, …) gap analysis
– Prototyping for risk reduction
– ITT requirements document (from 280 -> 90 pages)
– ITT definition: firm components, optional components
2009-06: Advert issued, Météo-France procurement
2009-09: Bidder selection
2009-11 to 2010-02: Three rounds of Negotiations

vGISC 2009 ITT Approach
Use off the shelf components where possible– Catalogue– Metadata editor– Entity management
Possibly use SIMDAT as ‘glue’
Tender for re-factoring & missing functionality– Monitoring and Administration– Subscription and pull request– Emphasis on interfaces
Tender for baseline and options
![Page 13: © Crown copyright Met Office GISC Exeter Status WMO RA VI Workshop on the Implementation of WIS Bulgaria, Sofia, 2011-11-01/03 Chris Little, Met Office,](https://reader036.vdocument.in/reader036/viewer/2022081513/56649ea95503460f94bad6f1/html5/thumbnails/13.jpg)

vGISC 2009 Project Approach
Open– Other partners (GISC and DCPC) are welcome!– Share the work– Candidate Open Source components proposed
Requirements– Light document: We know what we want, no options– Need to have the main requirements– Reasonable performances but a scalable system– ITT based on V1.5 of vGISC requirements document
Target– Solution that can be used by a large WMO community

WIS Summary
• Build up for last 10 years
• Change is really happening now
• Less ‘go it alone’ from WMO
• More use of external standards – ISO 19xxx, Inspire, … – OGC Web services: WMS, O&M, SWE, …– NetCDF, XML, … – Etc
• WMO strong point: persistence, bureaucracy!

Global Telecommunication SystemGlobal Telecommunications System (GTS)
– Managed by WMO - World Meteorological Organization
Use to exchange– Observations
– Forecasts
– Warnings
Private Network– Node to Node network
– NOT an Internet
– ‘Store and Forward’
– Resilient and inflexible
![Page 51: © Crown copyright Met Office GISC Exeter Status WMO RA VI Workshop on the Implementation of WIS Bulgaria, Sofia, 2011-11-01/03 Chris Little, Met Office,](https://reader036.vdocument.in/reader036/viewer/2022081513/56649ea95503460f94bad6f1/html5/thumbnails/51.jpg)
Global Telecoms System
• It works!
• Developed in early 1960s
• National, regional & international exchange
• Terrestrial & satellite links• Mainly point-to-point circuits, also Multi-point circuits
• X.25, IP & asynchronous links, Mixture of speeds
• Relatively expensive, legacy technologies
• Secure Extranet: limited use of Internet
• No overall system manager
• Store & Forward• No explicit addressing, based on distributed routeing directories
• Very robust, loosely coupled
• Very slow to change, ad hoc development
• Not used much for non-operational WMO data

WIS Background Summary
WMO Telecoms, GTS, is reliable, inflexible, ‘push’ only
Still many point-to-point links
Managed Network in Europe with two roles:– Areal Meteorological Data Comms Network AMDCN– Global Core/Main Trunk Network MTN
Some of Eastern Europe/Caucasus not yet joined
Some global centres still joining MTN– Brasil – Canada– South Africa
Other regions’ AMDCNs not yet happened.

WIS Background - 2CBS-Ext (2002) Cairns: Recommended FWISCongress Cg-XIV (2003)
– Multiplicity of systems of different Programmes causes incompatibilities, inefficiencies, duplication of efforts and higher overall costs.
– Congress approves the concept of the Future WMO Information System (FWIS), to provide a single coordinated global infrastructure for the collection and sharing of information in support of all WMO and related international programmes.
Executive Council EC-LVI (2004)– Identified FWIS to be one of the key contributions of
WMO to GEOSS– Established Inter-commission Coordinating Group on WIS
Executive Council EC-LVII (2005)– Renamed FWIS to WIS– Accelerated the development and implementation of WIS– Evolution not revolution, but faster than usual WMO
