2.10.3 Routeing catalogues
2.10.3.1 The procedures described here are recommended for the exchange of the routeing catalogues
of GTS Centres. The routeing catalogue is exchanged in the form of a file which can be directly ingested
into most database software packages to help in GTS data flow analysis. The files containing “routeing
catalogues” should be obtained using FTP file transfer over the Internet where possible and should be either
available at each Centre or from the WMO server. The WMO server should contain a list (with hyperlinks)
of all Centres who have routeing catalogues available for exchange. All Centres should provide the WMO
Secretariat with URL addresses of where their respective files are located.
2.10.3.2 The routeing catalogue of a GTS centre should provide the following information for each
bulletin identified by its abbreviated heading TTAAii CCCC:
(a) The GTS circuit on which the bulletin is received;
(b) The list of the GTS circuits on which the bulletin is sent.
2.10.3.3 Each RTH should prepare a routeing catalogue and make it accessible by the other GTS centres,
in particular by its associated NMCs. The routeing directory should be updated monthly if possible, but not
less than every three months.
2.10.3.4 A GTS centre should include in its routeing catalogue the abbreviated headings of all bulletins
received and/or transmitted on any GTS circuit connected to this GTS centre (GTS point-to-point circuits,
GTS point-to-multipoint circuits such as satellite distribution systems, including the remaining HF
broadcasts). Any bulletin scheduled to be received by the GTS centre, even if not actually forwarded on the
GTS, should be included in the routeing catalogue.
2.10.3.5 The bulletins received and/or transmitted on a circuit established under a bilateral agreement
for meteorological data exchange should also be included in the routeing catalogue.
2.10.3.6 The format of the routeing catalogue and the procedures for the access to the routeing catalogues
are given in the Attachment II-7. |
