Training Seminar on ICT for GTS (Bangkok, 23 - 27 September 2002) - Slide 1

Overview of the WWW monitoringOverview of the WWW monitoring


WWW monitoring plan

• The objective of the plan is to monitor:– The regularity of observations– The quality of observational data and correct coding– The completeness and timeliness of collection of

observational data at NMCs– The adherence to WMO standards and procedures– The exchange of observational data and processed

information on the GTS


WWW monitoring plan

• Ref.: Attachment I-5 to the Manual on the GTS

• Basic components:– Real-time monitoring– Non-real time monitoring– Follow-up corrective action

• The priority is given to:– TEMP, PILOT, SYNOP, SHIP, AIREP, AMDAR,

CLIMAT and CLIMAT TEMP reports


WWW monitoring plan

• Responsibilities– The responsibilities for the real-time monitoring and

non-real-time monitoring are given in Tables A and B of the Attachment I-5 to the Manual on the GTS

– The basic responsibilities rest with WMO Members– The WMO Secretariat co-ordinates the annual global

monitoring and specific monitoring exercises


WWW monitoring plan

• Frequencies of monitoring activities– Every day every centre carries out real-time

monitoring – At intervals of not more than one month, NMCs

should prepare monitoring reports– At least once every month, RTHs send a monitoring

report to their associated NMCs and adjacent RTHs– At least once every three months, WMCs send a

monitoring report to their adjacent RTHs


Real-time monitoring

• Procedures– Each centre should develop the necessary detailed

procedures – The procedures may vary from centre to centre– Some guidance is given in Table C of the

Attachment I-5 to the Manual on the GTS


Annual global monitoring

• Monitoring period: 1-15 October

• Data monitoring set:– SYNOP reports, parts A and B of TEMP, TEMP

SHIP and PILOT reports, SHIP, BUOY, AIREP, AMDAR, BATHY,TESAC, TRACKOB, CLIMAT and CLIMAT TEMP reports for global exchange

• Geographical areas to be monitored:– Zones of responsibility of the centre for the

collection



• The monitoring statistics may be sent to the WMO Secretariat :– on paper– on electronic media, preferably via Internet

• The WMO Secretariat analyse the monitoring statistics at the regional and global levels– The analysis is available in the WMO server

http://www.wmo.ch/web/www/ois/monitor/agm/agm.htm



• Main feature of the AGM:– It makes it possible to compare the availability of

reports from fixed stations at about 100 centres

• Main deficiencies– Implemented only once a year– The procedures make it difficult to compare the

availability of reports from mobile stations– Difference methods applied by centres to count the

reports lead to different monitoring results


Special MTN monitoring

• Objective for the development of the SMM– To develop a monitoring exercise which would have

not the main deficiencies of the AGM, and would complement the AGM

– To limit the additional resources to implement and operate the SMM

– To share the needed resources between the WWW centres



• Main features of the SMM– For each type of data:

• (e.g. SYNOP, SHIP etc.), several MTN centres took the responsibility to archive the complete bulletins with additional information (date/time of reception, centre from which the bulletins were received) and to transfer these raw data into the WMO FTP server

• one MTN centre took the responsibilities to make a pre-analysis of the raw data of the monitoring centres and to transfer the pre-analysis into the WMO FTP server



• Main features of the SMM– Analysis

• The Secretariat makes an analysis of the pre-analysis at the report and bulletin level, as well as RTH Toulouse at the bulletin level

• The analysis is available in the WMO FTP server under GTS_monitoring/SMM

• Monitoring periods– 1-15 January (February before 2003), April, July

and October
