GTS facilities in RTH Tokyo -Conceptual design- Message/File Switching System Back-end system • Central telecommunication facility in JMA was fully replaced in October 2005. • The new GTS switching system is composed by two UNIX servers in a cluster. Message editing Fax format conversion BUFR encode & decode Shared disk WMO monitoring cluster control NWP system Intranet systems Major functions supporting GTS operations + Message and Fax exchanges by both socket and so-called batched ftp through GTS + File exchanges by ftp through GTS + Collection of observational data by e-mail via the Internet
