DRAFT TEXT FOR INCLUSION IN THE GENERAL SUMMARY OF Cg-XIII
(agenda item 3.1.5)
- WMO Antarctic Activities
188.8.131.52 Congress noted with appreciation the work of the Executive Council through its Working Group on Antarctic Meteorology in coordinating the meteorological programmes in the Antarctic. It also noted that, despite the hostile conditions and the problem of logistics, the Antarctic Basic Synoptic Network (ABSN) had been well implemented and the number of reports received at the main telecommunication network (MTN) centres was close to the global average. Congress was pleased to note that in Antarctica, all OMEGA-based upper-air systems had been replaced by the Global Positioning System (GPS)-based systems and expressed its gratitude to the Members concerned for the active implementation of their meteorological programmes in the Antarctic.
[The EC Working Group on Antarctic Meteorology held its seventh session in Hobart, Australia from 7 to 11 September 1998 (see reference 1). The session evaluated the implementation of ABSN on the basis of monitoring results, reviewed the implementation of telecommunication networks in the Antarctic, and developed recommendations related to future activities of the working group, the revision of the ABSN, and the amendments to the Manual on the GTS. The recommendations will be submitted to EC-LI for approval. The working group also considered data-processing and climate issues as well as cooperation with other international organizations related to the Antarctic.]
- Congress noted with satisfaction that the International Symposium on Operational Weather Forecasting in Antarctica (Hobart, Australia, 31 August-3 September 1998), organized by the Bureau of Meteorology and co-sponsored by WMO had provided substantial results. The symposium proposed to develop an Antarctic Weather Forecasting Handbook. Congress fully supported the preparation of such a Handbook under the auspices of the WMO and requested the Executive Council to take appropriate action in this regard through its Working Group on Antarctic Meteorology.
- As regards the climate observations in the Antarctic, Congress was pleased to note that all Antarctic upper-air stations and most of the manned surface stations were included in the GCOS Upper-air or Surface Networks, and they provided a substantial contribution to the GCOS data sets. It also noted with satisfaction that the first version of the Catalogue of Antarctic Climate Data based on contributions provided by eight Members was prepared in January 1996. Noting that the electronic version of the Catalogue was under preparation, Congress urged Members, particularly those who had long-term records of Antarctic meteorological data to provide their contribution to the Catalogue.
- In view of the importance of the ozone measurements in the Antarctic, Congress urged Members concerned to expand ozone observations where possible and to make ancillary observations of ozone related chemical compounds, stratospheric clouds, aerosols and spectral radiation measurements. Congress encouraged Members to provide ozone data to WMO in near-real-time during the August-December period, and thereafter to deposit complete sets of observations on ozone and UV to the WMO WO3DC Toronto.
- Congress confirmed that cooperation between WMO and other international organizations related to the Antarctic, such as the Antarctic Treaty Consultative meeting (ATCM), the Scientific Committee for Antarctic Research (SCAR), Council of Managers of National Antarctic Programmes (COMNAP) and the Intergovernmental Oceanographic Commission (IOC), had been very fruitful and should be continued. Congress supported the initiative of ATCM to prepare a "State of the Antarctic Environment Report" which would serve as a "current account" of the state of the Antarctic environment acting as an alerting mechanism for emerging problems as well as providing a basis for environmental monitoring activities. Noting that SCAR had recently developed a possible framework for the report, Congress recommended to Members to provide their input to this report.
- Congress noted the new SCAR initiative to establish a project "Reference Antarctic Data for Environmental Research (READER)" with the goal of producing climatological fields of key variables such as near-surface temperature, wind velocity, long-wave radiation, etc. for Antarctica. Recognizing the high value of such a project for climate research in the Antarctic as well as for meteorological services for marine and air navigation and logistic operations, Congress urged Members to support the new SCAR initiative and to assist in implementation of the proposed project.
- In view of the importance of WMO Antarctic activities for meteorological services in support of marine and air navigation as well as for climate research and prediction, Congress decided that Resolution 6 (Cg-XII) (see reference 2) was to be kept in force.
