Overall programme assessement

…To be completed…

1.1 Global Observing System

Main results 2000-2001

Progress in the redesign of the GOS to attain a cost-effective composite and long-term sustainable global observing system; adjustment of the GOS regulatory material related to the review of operational aspectes of Automatic Weather Stations; review and strengthening of RBSNs for RA II, RA III, RA IV and RA V; a new concept of Regional Basic Climatological Network (RBCN) was developed and implemented in several regions enhanced the GOS support to GCOS; activities of COSNA, EUMETNET and NAOS were monitored and co-ordinated with GOS operations and the working programme of the CBS, as appropriate.


The implementation and progress of activities of the GOS followed in general its main long-term ojectives. Progress, in particular in the redesign of the GOS, was somewhat slower than planned because of shortages in Secretariat staff and continued constraints in obtaining the necessary degree of participation of Members’ volunteering experts. The project activity also involves close collaboration with the GDPS. The work was carried out in the framework of the CBS working structure. On average, the output of the GOS has become more reliable and sustainable, and the availability of climatological observations has increased. The alarming degradation of the radiosonde network of the second half of the last decade has been stopped and the level of station implementation and report numbers show now a slight upward trend. The negative impact of the cessation of the OMEGA radio navigation system has been fully overcome

1.2 Global Telecommunication System

Main results (2000-2001)

Plans for an improved Main Telecommunication Network (MTN) have been developed, and implementation has started; modern data-communication techniques (TCP/IP, FTP) were further introduced on the GTS resulting in increased data exchange capacities at lower cost; the Regional Meteorological Data Communication Network (RMDCN) in RA VI was successfully implemented and the number of participating RA VI Members has been reaching 70% and is still increasing; the implementation phase of a similar network project in RA III has started and similar plans are progressing in RA II; The RA V RMTN was upgraded, and a comprehensive telecommunication strategy for RA I has been adopted; satellite-based data distribution systems have been upgraded and the MDD was extended to the Western part of RA II; GTS operational procedures and provision of related operational and monitoring information were enhanced; data-handling and communication systems were introduced in the several developing National Meteorological Centres (NMCs), some of them received their first GTS connection; improved monitoring resulted in a more accurate identification of problems and more effective corrective action; support to other programmes, in particular the World Hydrological Cycle Observing System (WHYCOS), was expanded; radio frequencies allocations needed for meteorological operations and research were successfully safeguarded at the World Radio Communication Conference (WRC 2000) and preparatory activities for WRC 2003 were carried out.


The implementation and progress of activities of the GTS followed in general its main long-term ojectives. Telecommunication projects in RA II and RA III progressed somewhat slower than planned because some Members required more time to manage their financial commitments and align international with national legal procedure. The work was carried out within the framework of the CBS working structure and acccording to the priorities set by EC, the regional associations and CBS. The programme activities resulted in increased efficiency, cost-effectiveness and operational reliability of the GTS, technical improvements to GTS connections in some NMCs and the confirmation of all radio-frequencies allocations required for meteorological activities by WRC 2000.

1.3 Global Data-processing System

Main Results 2000-2001

The GDPS experienced a significant improvement in NWP quality; recommendations for implementation of procedures and standards for making widely available Ensemble Prediction Products (EPS) and related verification system for EPS products as an extension of procedures and standards for the deterministic products were developed and implementation is progressing; development and experimental implementation an updated verification system for long-range forecast was realised; initial development of the GDPS aspect of the infrastructure for long-range forecasting and contributing to the work of the inter-commission Task Team on regional climate centres was achieved; procedures and standards for data quality control were enhanced and implemented by the lead centres on surface, satellite, and aircraft data; GDPS support was provided to other WMO programmes and other International programmes through collaborative activities and related GDPS service delivery specifically for seasonal predictions, public weather services, aviation and environmental emergency response; capacity building in regional area model and/ post-processing facilities and interpretation of NWP products including EPS products was provided to developing NMCs through technical co-operation, technical conferences and workshops/ seminars.


The implementation and progress of activities of the GDPS followed in general its main long-term ojectives. The GDPS contributes substantially to the GOS project on the redesign of the GOS through the provision of OSEs and other related studies. activity also involves close collaboration with the GDPS. The output of the RSMCs has increased in terms of quantity , quality and introduction of new products. Many Members received training in the use of NWP products, and in particular new products, such as EPS. Standardised model output validation procedures support collaboration between GDPS centres. The priority activitiy to develop and provide to Members three-four days NWP forecast of severe weather is progressing as planned. Long-range forecast products are now available from web sites of more than ten major GDPS Centres and other institutes, and more than 50% of Members have direct access to at least one of these centres.

1.4 WWW Data Management

Main Results 2000-2001

The Year 2000 Problem was successfully mastered; new data management functions have been developed and proposed for implementation; the topology for the Future WMO Information System (FWIS) has been developed that would meet data exchange requirements of all relevant programmes; guidance on the co-ordinated operational use of the Internet by NMCs were developed and distributed; exchange and archiving of new data and products has been facilitated through several amendments to character and table-driven codes and the implementation of the new GRIB-2 by several centres; a strategy to migrate all WMO users from conventional character codes to table-driven codes has been started, which should eventually contribute to an increase in the availability of data and products and remove the costly effort of updating character codes; information on promising new information system technologies was exchanged and participants from developing countries were informed through a CBS technical conference on WMO information systems and services.


The implementation and progress of activities of the DM programme followed in general its main long-term ojectives. Members welcomed the guidance provided on the coordinated use of the Internet as a supplementary means to the GTS. The new integrated monitoring procedures are expected to facilitate the monitoring of data and products availability also in the context of Res. 40 (Cg-XII). The latter activity and the FWIS project activity involved close collaboration with the GTS.

1.5 WWW System Support Services incl. Operational Information Service

Main Results 2000-2001:

Strengthening of the implementation/operation/maintenance of meteorological observing, data processing and telecommunication systems, including satellite receivers and weather Radars as well as connection of NMCs to the GTS; improvement of the basic sytems infrastructure in RA I through developing and implementing the WWW Rehabilitation Plan focusing on selected national data collection systems, observing stations, GTS access and GDPS/DM functions; capacity building measures strengthened the NMHSs’ participation in and contribution to the WWW through facilitating participation of experts in meetings, technical conferences and training seminars related; development of innovative concepts were initialised for future long-term sustainable operations of the WWW; continued collaboration with consortia and groups such as COSNA and EUMETNET/EUCOS improved the GOS; studies were funded on the reasons for the low availability of climatological observations and the impact of loss of upper-air observations on NWP; OIS information was provided to users; improved effectiveness of the OIS through stronger use of the Internet for information collection and distribution, introduction of a CD-ROM service and elimination of printed products.


With partial financial support from the VCP, the WWW SSA assisted numerous Members in all Regions through the provision technical guidance, system maintenance, training and contributed thus to a more sustainable and cost-effective operation of WWW-related systems, functions and infrastructure. Priority was given to the RA I, where substantive progress was made in the development of a WWW rehabiliation plan and a comprehensive telecommunication strategy. In several countries the connection. The OIS continued successfully the initiative started in the previous Financial Period to improve the services and reduce the staff required. A P-position was made available for strenghtening the PWS programme. However, cutting back on operational cost through stronger use of the Internet and electronic publishing methods was slower than planned due to unforeseen departures of employees and their replacement with less experienced personnel.

1.9 Emergency Response Activities

Main Results 2000-2001:

Improved operational arrangements for response to nuclear incidents and other emergencies following new IAEA requirements including improved notification and warning procedures and practices for use of the Web; wider participation of NMHSs in the ERA programme; publication and dissemination to Members of guidance on effective response procedure to chemical incidents; procedures for dissemination of ERA products in response to other emergencies, including chemical and forest fires, were improved; approval by CTBTO and endorsement by EC of a draft relationship agreement and progressive implementation of co-operation arrangements including access of NMCs to CTBTO monitoring data to support WMO and related international programmes.


The programme activities of the emergency response related to nuclear accidents are firmly set within the framework of international cooperation between the IAEA and WMO, with WHO, FAO, EU, and OECD/NEA as other key partner agencies. The programme enjoys the full support of the eight designated RSMCs and the objectives were met and verified through period international exercises. Active participation in the programme grew to over 130 NMHSs. The ERA with respect to other environmental emergencies (e.g., land fires and chemical incidents) requires further development with respect to methodologies and procedures. The programme is an important contributor to raising the reputation and visibility of the NMHS in its country through the close cooperation with national disaster management agencies to which the NMHS provides unique and vital input during emergencies or related exercises.
