6 CMA’s Information Networks  GTS international network  CMA Wide Arae Network(WAN)  CMA Local Arae Network(LAN)

7 GTS  GTS(Global Telecommunication System) is the key component of WMO WWW(World Weather Watch) program  3 layers: Main Telecommunication Network(MTN), Regional Network, and National Network  MTN is the Kernel of GTS, interconnecting 3 World Meteorological Centres, and 15 regional telecomunication centres

8 GTS - Means of communication  point-to-point circuit: surface, ocean, and satellite links  multipoint-to-point: Data Collection Platform(DCP) of Meteorological Satellite  point-to-multipoint: satellite-based data broadcasting, radio facsimile broadcasting  Global, regional, national centres exchange of observation and product data

9 CMA’s International Network  GTS RTH Beijing RTH( Regioonal Tele. Hub ) on WMO GTS/MTN 64Kbps links with Offenbach and Tokyo Regional Links to Moscow, Bangkok, New Delhi, Seoul, etc Alpha server+VAX based, OpenVMS, to be replaced in 2003 with UNIX system X.25, Frame relay, TCP/IP Joining RMDCN ( Regional Meteorological Data Communications Network Project ) soon
