  3. State Council China Meteorological Administration Administrative Departments National Meteorological Centre Other Operational Centres Local Meteorological Bureaus

  4. Merging of the former National Climate centre to form the new National Meteorological Centre in 2001 Three sub-centres Weather Forecasting Climate Information System National Meteorological Centre

  5. The Organization of Meteorological Information Center Telecommunication Division High performance Computer Division Meteorological Information Center Network & Storage Division Lab. of Meteorological Data

  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

  12. CMNET - China Meteorological NETwork(sWAN） • Project code named “9210”, means approved in October, 1992 • CMA’s national meteorological operational information network • 1993-94 overall design, selecting of key technology • 1995- 96 pilot system • 1997-1999 full scale application software development; equipment deployment, trial-operation • 2000 operation started in Jan.

  13. CMNET - Components • Asiasat-2, Ku band transponder • VSAT based TCP/IP network • 1 hub station, 31 provincial stations, 300 small stations; data rate 512Kb/s (outbound) and 8*128Kb/s(inbound) • Satellite telephone network • PCVSAT data broadcasting network • with more than 2000 receiving stations, total data rate: 2 Mb/s

  14. CMNET - Application software • 3 Functional subsystems: data exchange, database, and operation supervision • developed by a single team for different levels of weather centres, centralized technical support • 3 different types of computers：IBM RS6000，DEC ALPHA、PC

  15. Asiasat-2 Regional Centres VSAT Control Center Server CHINAPAC PBX Surface backup network TCP/IP Provincial Weather Forecasting Offices National Operation Centres CMA’s VSAT Two-way Information Network City-level Weather Forecasting Offices Framework of CMNET -- 4 levels

  19. CMA‘s Campus Network（LAN） • History of LAN • 1989, implemented CDCNET and DECNET(10Mbps Ethernet) with installtion of CYBER main frame and VAX • 1989,using 50Mbps Local Couple Network(LCN) connecting CYBER and M360 and VAX and IBM main frame ，forming a heterogenous main frame network • 1995, implemented 100Mbps FDDI instead of LCN

  20. CMA‘s Campus Network • 2001, gigabit Ethernet implementation • Gigabit/s Ethernet L3switching, CISCO switch • connecting all office buildings in CMA’s headquaters • 4Gbps between core switchs • 2Gbps form office builldings to core switch • 100Mbps for desktop • Internet connection: 10Mbps
