2. REVIEW
OF THE STATUS OF IMPLEMENTATION AND OPERATION OF THE REGIONAL METEOROLOGICAL
TELECOMMUNICATION NETWORK
2.1 Status of implementation of RTHs, NMCs, MTN, inter-regional and regional links
2.2 Status of implementation of data-distribution systems via satellite and radio-broadcasts
Under the various sub-items, the meeting
will review the status of implementation and operation of the different
components of the RMTN, including point-to-point circuits, data distribution
systems based on telecommunication services via satellite, satellite-based data
collection systems (DCPs) and GTS facilities of RTHs and NMCs. The meeting will also review the status of
operation of other telecommunication systems or services in the Region,
including fax and RTT radio-broadcasts, collection of reports from oceanic
areas through INMARSAT and coast telecommunication stations, and also usage of
telecommunication and data-communication networks and services (e.g. PSPDN, PSTN). The use of the Internet will be considered
under item 4.1.
All
participants are invited to submit a contribution on this matter as regards
his/her own RTH and the associated NMCs.
2.3 Review of the exchange of observational data and products
The meeting will review the operational
aspects of the collection of observational data, and the status of the
distribution of observational data and of processed information in the Region,
including transmission programmes. The
meeting is expected to identify the deficiencies and to formulate
recommendations with a view to improving the exchange and availability of data
and products within the Region as well as with other neighbouring Regions.
Participants
are invited to submit views and contributions.
3. IMPLEMENTATION PLAN FOR THE FURTHER DEVELOPMENT OF THE REGIONAL METEOROLOGICAL TELECOMMUNICATION NETWORK
3.1 Data communication techniques and procedures
3.2 Operational procedures and information
The meeting will review data communication
techniques and protocols (e.g. TCP/IP and related protocols), as well as
operational procedures applicable to the RMTN, including operational
information (Pub.9 Vol. C1 and C2 and RTH routeing catalogues), taking into
account the related outcome of CBS and RA V.
It will develop recommendations for implementation as appropriate.
3.3 FWIS overview
The meeting will be informed of the current development of the Future WMO Information System concept.
3.4 RMTN development planning, (including data distribution systems)
The meeting will develop co-ordinated
planning and implementation guidelines for the further development,
strengthening and upgrade of the GTS in Region V, taking benefit of new
telecommunication techniques and services, including TCP/IP based services
(FTP, Web), Frame Relay and managed data communication network services. The
meeting is expected to review implementation plans for systems based on
multipoint telecommunication services via satellite (e.g. EMWIN), including
coordination aspects related to the ICAO/WAFS satellite-based telecommunication
system (SADIS and ISCS). The meeting
will review plans as regard radiobroadcasts and the possible introduction of
new satellite-based systems (DVB and DAB).
The meeting will review technical and operational guidance to NMHSs for
the use of telecommunication and data-communication networks and services.
Participants and, in particular,
Mr Kevin Alder (New Zealand) Coordinator on regional aspects of
information systems and services, are invited to submit proposals.
3.5 National GTS components (national centres and networks)
The meeting will review data-communication
techniques, equipment and services applicable to NMCs and RTHs and to national
meteorological telecommunication networks with a view to providing guidance for
a cost-effective implementation and strengthening of the GTS at the national
level in RA V, particularly with respect to national data-collection. It may also wish to consider possible
back-up arrangements at NMCs in case of natural disasters.
Participants
are invited to submit proposals.
4. OTHER
INFORMATION SYSTEMS AND SERVICES ISSUES
4.1 Utilization of the Internet
Through a one-day workshop held jointly with an Expert meeting on enhanced use of data-communication services, the meeting will review the utilization of the Internet by NMHSs for the exchange of meteorological and related information. It will assess the experience gained and identify relevant technical and/or operational issues, taking into account the guidance developed by CBS.
Participants
are invited to submit proposals.
4.2 Data representation and codes
The meeting will review data representation and codes, taking account the related conclusions and recommendations of CBS. It will consider possible regional issues.
Participants
are invited to submit proposals.
4.3 Migration to table-driven code forms
The meeting will review the plan for
migration to table-driven code forms
as developed by CBS and endorsed by Cg-XIV, and will consider its regional
implications.
5. IMPLEMENTATION
COORDINATION AND SUPPORT ACTIVITIES
Taking into account implementation plans
developed under item 3, the meeting is invited to consider cooperation and
support activities, including training aspects, possibly required for
facilitating upgrade of the RMTN. The
meeting will be invited to recommend priorities in this respect, especially in the framework of WMO technical
co-operation programme activities.
6. RADIO-FREQUENCIES
FOR METEOROLOGICAL ACTIVITIES
The meeting will be informed of the issues
related to the frequency bands allocated to meteorological activities,
including radiosondes, meteorological
satellites, spaceborne passive remote sensing, weather and wind profiler
radars.
