WMO Regional Training Seminar for National Trainers of RA III and RA IV / Expert Team on Requirements for Data from Automatic Weather Stations / Third session of the Commission for Instruments and Methods of Observation Expert Team on Upper-Air Systems IntercomparisonsandInternational Organizing Committee on Upper-Air Systems Intercomparisons / CBS Expert Team on the Evolution of the Global Observing System / EC outcomes
This training event was one of a series of WMO Regional Training Seminars for National Trainers. The primary focus was on the developing of participants’ skills through active engagement in designing and delivering training events. Presentations on severe weather prediction and related satellite meteorology were delivered in order to update the knowledge of participants on these important topics and to show them how they can be taught. MOODLE software was demonstrated as an efficient training management tool before, during and after the training event.
This meeting was attended by five Expert Team members as well as by representatives of the WMO Commissions for Instruments and Methods of Observation, for Climatology and for Agricultural Meteorology and EUMETNET.
The meeting considered the issues requested by the 2006 extraordinary session of the Commission for Basic Systems and formulated several recommendations to the Implementation-Coordination Team on the Integrated Observing System.
It addressed items related to the functional specifications for automatic weather stations (AWS); requirements for a robust AWS suitable particularly for remote locations; calibration and ground truth of space-based observations; generic and sensor-specific requirements to improve the capability of AWS to report meteorological parameters addressing user requirements; optimization of observing networks; guidelines for transition to automated observations; development of AWS metadata catalogues; guidelines for the siting classification of surface observing stations; the basic set of variables to be reported by a standard AWS for multiple users; BUFR (see WMO codes) descriptors related to AWS metadata transmission; validation of the BUFR template for surface observations from a one-hour period and for reporting SYNOP data in BUFR; vision for the Global Observing System in 2025; advances in AWS technology, and actions in the Expert Team on Evolution of the Global Observing System’s Implementation Plan related to automatic weather stations.

The joint third session of the Commission for Instruments and Methods of Observation Expert Team on Upper-Air Systems Intercomparisons
The meeting reviewed previous intercomparisons/tests, requirements for future Intercomparisons, testing requirements for the Global Climate Observing System (GCOS) Upper-Air Reference Network (GRUAN) network. Main attention was focused on the eighth WMO Intercomparison of Radiosonde Systems.
The manufacturers’ representatives presented the changes made in their in radiosondes after the WMO Intercomparison of High Quality Radiosonde Systems, (Vacoas, Mauritius, 2005) and explained details of functional tests made on new designs. The Expert Team/International Organizing Committee (ET/IOC) reviewed the positive changes in the designs of radiosondes of all manufacturers since 2005 and discussed their impact on global radiosonde data compatibility and the need for a new global radiosonde intercomparison.
The results of several recent international and national radiosonde tests, as well as progress on testing interoperable upper-air systems were presented and discussed. Presentations on progress in the further development of other upper-air measurement systems and related planned projects were also given, namely UKMO FUND Project, COST Action ES0702 EG-CLIMET, CN-MET Project of MeteoSwiss and LUAMI Campaign. In this context, the ET/IOC considered the requirements for future tests/intercomparisons of upper-air systems and updated its work plan.
The attention was given to the testing requirements for the GRUAN network considering the outcomes of the Initiation GCOS Reference Upper-Air Network Meeting, Germany, February, 2008. The ET/IOC noted that the ET should assist GRUAN in developing the best operational practices. The results of the discussion were reflected in the updated ET work plan.
The ET/IOC gave its main attention to the elaboration of both operational and organizational aspects of the eighth WMO Intercomparison of Radiosonde Systems, to be held in China in 2010. In the preparation of planning for future WMO global and regional radiosonde intercomparisons, the ET/IOC took into account the need for global intercomparison driven by the changes made in the designs of the high-quality operational radiosondes. It was decided to organize the eighth WMO Intercomparison of Radiosonde Systems (WMO-RSO-8) in early 2010, followed by the WMO Regional Intercomparison within two years, if required. The planned WMO Regional Intercomparison in China in 2009 would, therefore, be organized at a later stage, if China was not able to join the WMO-RSO-8. In addition to the general rules and procedures for WMO intercomparisons, as defined in the Guide to Instruments and Methods of Observation (WMO-No. 8), Part III, Chapter 5, Annex 5.A and 5.B, and Part I, Chapter 12, Annex 12.C, the ET/IOC agreed on the all rules and procedures for the eighth WMO Intercomparison of Radiosonde Systems.

This meeting was held at WMO headquarters under the chairmanship of John Eyre.
The ET reviewed several activities related to the Integrated Observing System, such as the WMO Integrated Global Observing Systems, the Group on Earth Observations/ Global Earth Observation System of Systems, WMO’s World Weather Research Programme-THORPEX, International Polar Year 2007-2008, the African Monsoon Multidisciplinary Analysis project, the Aircraft Meteorological Data Relay programme, the Global Climate Observing System, the EUMETNET Composite Observing System and the Expert Team on Requirements for Data from Automatic Weather Stations, and took them into consideration when revising the Implementation Plan for the Evolution of the Global Observing System e WMO Integrated Global Observing Systems, the Group on Earth Observations/ Global Earth Observation System of Systems, WMO’s World Weather Research Programme-THORPEX, International Polar Year 2007-2008, the African Monsoon Multidisciplinary Analysis project, the Aircraft Meteorological Data Relay programme, the Global Climate Observing System, the EUMETNET Composite Observing System and the Expert Team on Requirements for Data from Automatic Weather Stations, and took them into consideration when revising the Implementation Plan for the Evolution of the Global Observing System (EGOS-IP) and preparing a new vision for the Global Observing System in 2025.
As part of the Rolling Review of Requirements process, the ET reviewed the status of the WMO/ Committee on Earth Observation Satellites database of user requirements for observations and of observing system capabilities. It defined detailed actions for the review and updating of the database. The ET then reviewed the status of Statements of Guidance (SoGs) in 12 application areas with special focus on nowcasting and very short range rorecasting, ocean applications and climate applications. In each case, it either approved the proposed new version for publication on the WMO Website or agreed actions needed to prepare an updated version.
The ET reviewed the surface- and space-based sub-systems of the Global Observing System within EGOS-IP and prepared a revised version, as a record of recent progress and next actions. This review took note of comments from other relevant groups. The ET also considered reports on the responses to EGOS-IP in all WMO Regions, as well as from WMO Members. The analysis of responses from National Focal Points was presented and discussed.
In line with WMO strategic planning, the ET discussed the preparation for the ICT-IOS-5 and CBS-XIV, preceded by the Technical Conference on the WMO Integrated Global Observing Systems (TECO-WIGOS) (23-24 March 2009). In so doing, the ET agreed on the recommendations to ICT-IOS and CBS-XIV, including a draft work plan for the ET for the next intersessional period for consideration by ICT-IOS-5.
