Lead Centre Monitoring

Lead Centres have been established by CBS for coordinating the monitoring results of specific observation types. The Lead Centres produce six-monthly consolidated reports of the observations of the data type they have been entrusted to monitor that display consistently low quality. These reports are also known as 'suspect' lists. The following lead centres have been established.

Approved quality monitoring procedures and formats for the exchange of the monitoring results have been developed. It should be noted that the selection criteria for 'suspect' data is stricter than the monthly monitoring criteria published in the Manual on the GDPS as Attachment II.8.  This is primarily  due to the larger sample size used for the six-monthly monitoring.

The six-monthly consolidated suspect reports are distributed to Members so that they can take remedial action as required. Recommendation 8 CBS-XI) and Recommendation 2 (CBS-Ext.(94)) provide for notification of Members/agencies responsible for observations of low quality. These Members/agencies then report to lead centres and the WMO Secretariat on their remedial efforts.
