67 ROBEX Handbook 1 1. INTRODUCTION 1.1 The Regional Operational Meteorological (OPMET) Bulletin Exchange (ROBEX) scheme was established by the MID/SEA COM/MET Regional Planning Group at its first meeting, July 1972, Bangkok. The scheme became operational in 1974 and has since been successfully serving the ASIA/PAC and MID ICAO Regions in the exchange of the required OPMET information. 1.2 The ROBEX scheme was intended initially only for METAR exchange; AIREP and TAF exchanges were added to the scheme at a later stage. The operation of the ROBEX scheme included exchange of OPMET bulletins between the originating tributary offices and the bulletin compiling centres, which, according to their functions and responsibilities, were classified as Main Collection Centres or Sub-collection Centres, or TAF Collection Centres. The operational exchange has been carried out according to agreed transmission schedules; the bulletin contents were specified in the ROBEX Handbook. 1.3 Based on COM facilities of very limited capacity in the early seventies, the ROBEX scheme was strictly planned to accommodate only those OPMET exchanges considered vital for the flight operations. Over the years, the COM facilities have been improving considerably and the ROBEX scheme has been developing accordingly. 1.4 Recently, it has been identified that significant changes in the scheme were needed in order to make it compatible with the existing COM environment and satisfy the evolving user requirements. In view of this, APANPIRG adopted conclusions that called for further development of the ROBEX scheme according to the new operational requirements. 1.5 The ROBEX Handbook is the main guidance material providing detail on the procedures for OPMET exchange under the ROBEX scheme. The Handbook defines the responsibilities of the ROBEX centres and the procedures to be followed. It defines also the content and format of the ROBEX bulletins. 1.6 The ROBEX Handbook is published and kept up-to-date by the ICAO Office, Bangkok in coordination with ICAO Office, Cairo.

68 ROBEX Handbook 2 2. ROBEX SCHEME GENERAL 2.1 Objective The main purpose of the Regional Operational Meteorological Bulletin Exchange (ROBEX) Scheme is to: 2.2 Structure - ensure the most efficient exchange of OPMET information within the ASIA/PAC and MID Regions as well as with the other ICAO regions to meet the requirements by the users of OPMET information; and - ensure the implementation of the OPMET-related SARPs in Annex 3 and Annex 10, and the relevant provisions of the ASIA/PAC and MID Air Navigation Plans (ANP) in a highly efficient and standardized way The above objective is achieved by implementing a number of ROBEX collecting and disseminating centres (ROBEX centres), regional OPMET data banks (RODB), and interregional OPMET gateways (IROG). All these operational units form the ROBEX scheme. In order to ensure seamless global exchange of the required OPMET information the ROBEX scheme should be developed in compliance with similar structure in the other ICAO regions, as well as with the AFS satellite distribution systems and internet based services (SADIS, Secure SADIS FTP and WIFS) used to disseminate OPMET data. 2.3 Products The ROBEX scheme produces and delivers to the aviation users the required OPMET information in the form of predefined bulletins. The scheme should handle all types of OPMET information in alphanumeric bulletin form and should provide facilities and services for scheduled and non-scheduled delivery of OPMET information to the users. 2.4 Management Monitoring of the OPMET exchange under the ROBEX Scheme, planning for improvements and preparation of proposals for any changes of the Scheme that may become necessary, are carried out by the ASIA/PAC Air Navigation Planning and Implementation Regional Group (APANPIRG) and the Middle East Air Navigation Planning and Implementation Regional Group (MIDANPIRG). In order to achieve these tasks, the ROBEX implementation status and planning is part of the agenda of the MET sub-groups of the two PIRGs. Note:When necessary, supplementary expert groups can be established by the PIRGs or the CNS/MET Sub-groups to deal with OPMET specific issues. The Meteorological Information Exchange Working Group (formerly the ROBEX Working Group and the OPMET Management Task Force) is currently tasked to deal with all OPMET related issues in the ASIA/PAC region.

69 ROBEX Handbook Any proposals for amendments to the ROBEX scheme, which States or international organizations concerned consider necessary, due to changes in the operational requirements for OPMET data or to developments of the AFS system, should be forwarded for consideration by the ICAO Asia and Pacific Office, Bangkok and/or the ICAO Middle East Office, Cairo. 2.5 Documentation The ROBEX Handbook is the main guidance material related to the ROBEX scheme. It should be kept up-to-date by the ICAO Asia and Pacific Office, Bangkok in coordination with the ICAO Middle East Office, Cairo The ASIA/PAC OPMET Data Banks Interface Control Document (ICD) is a supplementary document, which provides users with guidance on the interrogation procedures and the content of the RODBs. This document at present covers only ASIA/PAC Region. The ICD should also be kept up-to date by the ICAO Asia and Pacific Office, Bangkok. Note: The MID Region is served by the international OPMET data bank in Vienna.

70 ROBEX Handbook 4 3 OPMET INFORMATION AND OPMET EXCHANGE 3.1 OPMET data types The following OPMET data types should be handled by the ROBEX scheme: Data type Abbreviated name WMO data type designator Aerodrome reports METAR SPECI SA SP Aerodrome forecasts TAF: 12 to 30 hour 9 hour FT FC SIGMET information SIGMET SIGMET for TC WS WC Volcanic ash and tropical cyclone advisories SIGMET for VA Volcanic Ash Advisory Tropical Cyclone Advisory WV FV FK Air-reports AIREP SPECIAL (ARS) UA Administrative ADMIN NO Note that IATA TAF requirements in the ASIA/PAC region are for TAF validity of either 24 or 30 hours. Some States issue 12- and 18-hour TAF which don t meet requirements, but are nevertheless classified as FT for the WMO data type designator. The ASIA/PAC Regional Air Navigation Plan does not include any requirement for 9-hour validity aerodrome forecasts in TAF code (9H) classified as FC for the WMO data type designator. 3.2 OPMET bulletins The exchange of OPMET data is carried out through bulletins containing one or more meteorological messages (METAR, SPECI, TAF or other OPMET information). An OPMET bulletin contains messages of the same type The format of OPMET bulletins is determined by: - ICAO Annex 10, Aeronautical telecommunications, as regards the AFTN envelope of the bulletin; - WMO-No.386, WMO Manual on the Global telecommunication System, as regards the WMO abbreviated heading of the bulletin; - ICAO Annex 3 and WMO-No.306, Manual on Codes, as regards the format and coding of the information included in the bulletin. 3.3 Types of OPMET exchange Regional exchange ROBEX scheme The ROBEX scheme covers the exchange of OPMET information in the ASIA, PAC and MID ICAO regions. It includes several types of exchanges as described below.

71 ROBEX Handbook Regular Exchange under ROBEX. This is a scheduled exchange that encompasses collection of messages from the originating stations, compiling of bulletins and their dissemination according to predetermined distribution schemes. The collection and distribution is carried out at fixed times and the bulletin content is defined in the current Handbook Non-regular exchange. This includes: a) Exchange on request (request-reply service). The RODBs store OPMET data and make them available on request. b) Exchange of non-routine reports: SPECI; TAF AMD; SIGMET; TCA and VAA; ADMIN messages Inter-regional OPMET exchange Exchange of OPMET data between the ASIA/PAC, MID and the other ICAO Regions is carried out via designated centres, which serve as Inter-regional OPMET Gateways (IROG). An IROG is set up for sending/receiving specified OPMET data between ASIA/PAC and every other ICAO region for which ASIA/PAC OPMET data are required. Note: The former name of these centres is ODREP Inter-regional OPMET exchange via IROGs is carried out through the ground segment of the AFS (currently, through the AFTN or AMHS) Exchange of OPMET information through the satellite segment of the AFS and the associated Internet systems The satellite broadcast provided by the United Kingdom (SADIS) and the Internet systems provided by the United Kingdom (Secure SADIS FTP) and the United States (WIFS) form another type of OPMET exchange, which is global in nature and is intended to cover the emerging requirement for global access to all available OPMET data All ASIA/PAC and MID OPMET data handled by the ROBEX scheme should be relayed to the SADIS/Secure SADIS FTP and WIFS service providers for uplink or distribution through SADIS/Secure SADIS FTP and WIFS Other OPMET exchanges Where OPMET exchanges described in the above paragraphs are not sufficient, direct AFTN or AMHS addressing should be utilized by the originating centres or NOCs.

72 ROBEX Handbook 6 4 COMPOSITION OF ROBEX 4.1 ROBEX scheme involves a number of aeronautical meteorological stations, aeronautical telecommunication stations, aerodrome meteorological offices and other operational units. The following operational units should be considered as components of the ROBEX scheme: Originating station an aeronautical meteorological station or an aerodrome meteorological office, or a forecasting office, or a MWO, or a TCAC, or a VAAC. The duties and responsibilities of these originating stations should be defined by the State s meteorological authority National OPMET center (NOC). Normally, a NOC is associated with the State s national AFTN centre/switch or AMHS. The role of the NOC is to collect all OPMET messages generated by the originating stations in the State and to send them to the responsible ROBEX bulletin compiling center (ROBEX BCC). Some NOCs serve also as ROBEX BCCs. National regulations should be developed to ensure that NOCs disseminate the international OPMET data within their own State, as necessary ROBEX bulletin compiling centre (ROBEX BCC or, in brief, ROBEX centre) ROBEX centres are responsible for collection of OPMET messages from the originating stations or NOCs in their area of responsibility and for compiling these messages into ROBEX bulletins. Tables A and B, in Appendices A and B respectively of the ROBEX Handbook determine the areas of responsibility (or, collection areas) of the ROBEX centres for METAR/SPECI and TAF The ROBEX centres are responsible for the transmission of the bulletins compiled by them to: - other ROBEX centres, according to predefined distribution lists, specific for each bulletin; - ASIA/PAC RODBs; - NOCs or other COM or MET offices in the States in their area of responsibilities, as agreed between the ROBEX centre and the States authorities concerned. Note: The former ROBEX scheme involved separate compiling centres for METAR and TAF (METAR collection centres, and TAF collection centres). In some cases, METAR from an aerodrome was compiled by one METAR collection centre, and the TAF from another TAF collection centre. The evolution of ROBEX should be towards unified ROBEX centers responsible for collecting/distributing of all OPMET data types within their area of responsibility Regional OPMET Data Banks (RODB) Five centres have been designated by APANPIRG (APANPIRG Conclusions 4/35 and 5/21 (1994)), to serve as Regional OPMET Data Banks: Bangkok, Brisbane, Nadi, Singapore and Tokyo. The Asia/Pacific OPMET data banks interface control document reflects the requirements for the operation of the ASIA/PAC OPMET data banks to support the ROBEX Scheme.

73 ROBEX Handbook The main responsibilities of the RODBs are defined, as follows: - to support the ROBEX Scheme and to facilitate a regular exchange of OPMET information based on predetermined distribution within the ASIA/PAC Regions; - to operate as Inter-regional OPMET Gateway (IROG) with responsibility of exchanging OPMET information between ASIA/PAC Region and the adjacent Regions; and - to provide facilities for request/response type of access to the stored OPMET data for users to obtain non-regular or occasional information. Note. The interrogation procedures applicable to the OPMET data banks and catalogues are provided in the ASIA/Pacific OPMET Data Banks Interface Control Document (ICD), published and maintained by the ICAO Asia and Pacific Office, Bangkok. Note responsibilities of RODBs are given in , 10.2, 10.3 and Inter-regional OPMET Gateways (IROG). The Inter-regional OPMET Gateways in ASIA/PAC Region are the designated RODBs. Each RODB is assigned responsibility for exchange of OPMET information with other ICAO Regions. The responsibilities of the IROGs for ASIA/PAC and MID Region are shown in p of this Handbook Support to SADIS/Secure SADIS FTP and WIFS satellite and Internet broadcasts. The RODBs and IROGs should facilitate the global exchange of OPMET data carried out through the SADIS/Secure SADIS FTP and WIFS satellite and Internet broadcasts. In order to achieve this, close liaison should be maintained between the IROGs and the corresponding SADIS/Secure SADIS FTP and WIFS gateways. Availability of ASIA/PAC and MID data on SADIS/Secure SADIS FTP and WIFS should be monitored and any systematic shortfalls of data identified should be reported to the relevant ICAO regional office. 4.2 The overall structure of the ROBEX scheme and AFTN plan (Chart CNS 1) is presented in the following figures.
