Outcome of the Implementation Co-ordination meeting on the GTS in Region VI (Eastern part) (Moscow, 24 to 27 April 2001). 1. An Implementation Co-ordination meeting on the GTS in Region VI (Eastern part) was held in Moscow from 24 to 27 April 2001. Experts from Armenia, Azerbaijan, Belarus, ECMWF (partially), Georgia, Kazakstan, Republic of Moldova, Russian Federation and Ukraine participated in the meeting. 2.1 Status of implementation of the centres, circuits and broadcasts

Status of the implementation of the centres 2.1.1 In the Eastern part Region VI, four centres are automated (Minsk, Kiev, Tbilisi and Moscow) and three centres are not automated (Kishenev, Baku and Yerevan). Kazakstan is in the zone of responsibility of RTH Tashkent. NMC Almaty is automated. Status of the implementation of the circuits 2.1.2 The regional meteorological telecommunication plan in Region VI calls for the implementation of point-to-point circuits (see Figure 1). 2.1.3 Thirty-two RA VI Member countries are connected to the Regional Meteorological Data Communication Network (RMDCN). None of the countries located in the zone of responsibility of WMC/RTH Moscow are connected to the RMDCN. 2.1.4 The five following countries are connected to the RMTN by dedicated point-to-point circuits operating at a speed of 9600 bits/s or higher: Belarus, Georgia, Republic of Moldova, Russian Federation, and Ukraine. Four NMCs (Minsk, Kiev, Tbilisi and Baku) have direct telephone channels with WMC/RTH Moscow. The Moscow – Baku telephone-type circuit is not currently in operation, but will be put into operation in the near future. NMC Yerevan is connected to WMC/RTH Moscow via Internet, as well as over a telegraphic circuit through Rostov. Two NMCs (Kishenev and Yerevan) have no direct circuits with any of the RTHs, including WMC/RTH Moscow. 2.1.5 At present Azerbaijan and the Republic of Moldova transmit data to Moscow by the switching telegraphic network, and receive data from Moscow via Internet and the TV-InformMeteo system, operated by Russian Federation. 2.1.6 NMC Almaty is connected to RTH Tashkent and WMC/RTH Moscow by medium-speed dedicated circuits. 2.1.7 The TCP/IP protocol is used on the regional circuits Moscow - Minsk and Moscow – Tbilisi, and on the inter-regional circuit Moscow – Almaty. 2.1.8 The MTN circuits Moscow - Bracknell and Moscow - Prague as well as the regional circuit Moscow - Norrköping are operated through direct analogue channels at the rate of 9600-14400 bits/s. The operation of the MTN circuit Moscow - Sofia was discontinued in 2000. The X.25 protocol is used on the circuits Moscow-Bracknell and Moscow - Norrköping and the FTP protocol is used on the circuit Moscow - Prague. The procedure for using the RMDCN for the circuit Bracknell - Moscow has started and by the end of 2001 the Moscow - Prague circuit is scheduled to be part of the RMDCN. State of the implementation of the multipoint telecommunication systems 2.1.9 The regional meteorological telecommunication plan in Region VI includes the implementation of multipoint telecommunication systems (see Figure 2).

2.1.10 Four countries (Armenia, Belarus, Georgia and Ukraine) are equipped to receive RETIM and five countries (Armenia, Azerbaijan, Georgia, Republic of Moldova and Russian Federation) are equipped to receive TV-Inform-Meteo. Access to the Internet 2.1.11 NMHSs of Armenia, Azerbaijan, Belarus, Kazakstan, Republic of Moldova, Russian Federation and Ukraine have access to the Internet. Georgia was implementing the access. The countries use the Internet to exchange data and products either as a primary means (e.g. Azerbaijan) or as a back-up means. 3. Analysis of the weaknesses and opportunities with respect to the implementation and operation of the GTS in the eastern part of Region VI

3.1 The meeting noted the following weaknesses in the implementation of the GTS in the eastern part of Region VI:  NMCs Baku, Kishenev and Yerevan are not automated.  Some GTS circuits are not implemented or are implemented at a low speed.  Medium-speed circuits are analogue telephone circuits, which are less reliable and efficient than digital circuits.  The protocol TCP/IP is not used on all circuits. 3.2 The meeting noted the following opportunities to improve the implementation and operation of the GTS in the eastern part of Region VI:  To automate NMCs Baku, Kishenev and Yerevan.  To implement digital circuits using TCP/IP protocol. The transport service for the GTS may also be based on the use of Frame relay services such as the Regional Meteorological Data Communication Network (RMDCN). However, the meeting was of the opinion that the connection of the NMHSs to the RMDCN still remained much more expensive than the implementation of dedicated circuits. The connection to the RMDCN should be envisaged when the costs of the dedicated circuits and the costs of the RMDCN services would converge and the use of the RMDCN would become economically and technically attractive.  To complement the exchange of data and products on point-to-point circuits by the reception of satellite-based data distribution systems. 4. Recommendations for the improvement of the GTS in the eastern part of Region VI

4.1 The meeting recommended the following action for improving the GTS in the eastern part of Region VI:  To automate NMCs Baku, Kishenev and Yerevan. Taking into account the financial limitations, it is suggested to implement a minimum set of MSS functions as follows: automation of the reception of observational data from RBSN stations, compilation of bulletins and transmission of the compiled bulletins to the RTH in accordance with the WMO standard protocols, reception of observational data and processed information from the RTH and/or adjacent centres and their visualisation, connection to the NMC LAN, and interface with the users’ terminals and other data transmission systems (RETIM, TV-Inform-Meteo) in accordance with standard protocols. During the meeting, the specifications for the automation of the NMCs were prepared.  To put into operation the circuit Moscow - Baku.  To arrange for the implementation of direct circuits between Moscow and Yerevan, and between Kiev and Kishenev.

 To arrange for the automatic switching of GTS messages on the triangle Moscow – Kiev – Minsk. In this respect, a router should be installed at NMC Kiev and the WMO TCP/IP protocol should be used. The circuit Moscow - Minsk should be upgraded during 2001 from an analogue circuit to a digital circuit operating at 64 Kbits/s. The upgrading of the analogue circuit Moscow – Kiev to a digital one should be considered.  To increase the reliability of the operation of the MSS in NMCs Almaty and Tbilisi by ensuring a guaranteed power supply.  To protect NMC Almaty and the relevant part of the GTS from unauthorised access from Internet by installing a router (firewall).  Within the framework of the upgrading of the RETIM system (RETIM2000), to consider the possibility of upgrading the hardware and software installed in NMCs Yerevan, Kiev, Minsk and Tbilisi in a LAN version.  To make the information included in Volume C1 of WMO Publication No. 9 consistent with the list of RBSN stations and real observations, and transmit accordingly the observations. A special list of stations, which should transmit CLIMAT and CLIMAT TEMP data, should be established in Region VI as it was done in Region II.  In the GTS plan in Region VI, to include the multipoint telecommunication system TV-InformMeteo system, and the circuits Moscow – Baku and Baku – Ankara, and to delete the circuits Minsk – Riga and Moscow – Warsaw, which are not in operation. The countries concerned should send formal confirmations to the WMO Secretariat. 4.2 The meeting also recommended that the WMO WWW server should provide information in Russian; as a first step, appropriate links should be included to access the documents which are already available in Russian. 5. Implementation co-ordination and support activities

5.1 If the WMO Members concerned require support to implement the recommendations given in paragraph 4, they should send to the WMO Secretariat the appropriate requests for supporting their respective projects under the WMO Voluntary co-ordination Programme (VCP). The meeting felt that the projects for the automation of NMCs Baku, Kishenev and Yerevan should be considered with the highest priority and that the other projects related to the recommendations given in paragraph 4 should be considered with a high priority. The meeting recommended that the countries designate focal points for the preparation of the projects. 5.2 With a view to ensuring a successful implementation of the projects related to the automation of NMCs Baku, Kishenev and Yerevan within the framework of the GTS, it is necessary to co-ordinate the following issues:  For NMC Baku, to put into operation the circuit Moscow - Baku.  For NMC Kishenev, to determine the date of implementation and operation of the circuit Kiev – Kishenev, the protocol to be used on this circuit (FTP?), and the type of modem; to co-ordinate with NMC Bucharest the type of protocol for the exchange of data and charts; for the installation of the RETIM station, to co-ordinate with the donor the interface (protocol) between the MSS and the RETIM station via the LAN, including the IP address.  For NMC Yerevan, to determine the date of implementation and operation of the circuit Moscow – Yerevan; to co-ordinate the interface (protocol) with the RETIM station and the IP address. 5.3 NMC Kishenev proposed to consider the possibility to exchange data between RTH Moscow and NMC Kishenev through NMC Bucharest. If NMC Bucharest agrees, such an exchange can be arranged. However, it was stressed that the most reliable way of exchanging data would the establishment of a direct logical circuit between the RTH and the NMC.
