World Meteorological Organization

The WMO Secretariat prepares each year an analysis of the monitoring results provided by the WWW centres for SYNOP, TEMP, PILOT and CLIMAT reports. The RBSNs and the RBCNs are used as reference monitoring datasets.

• The National Meteorological Centres (NMCs) should monitor data from their own territory;

• WMCs (World Meteorological Centres) and RTHs located on the MTN (Main Telecommunication Network) should monitor the complete global data set.

• Regional Telecommunication Hubs (RTHs) should at least monitor data from their associated NMCs and their own Region;

The results of the AGM make it possible to compare the availability of reports received from RBSCN stations at the NMC responsible for inserting the data in the Regional Meteorological Telecommunication Network (RMTN), at the associated RTH and at MTN centres.  The differences in the availability of data between centres are due to the following main reasons:

• Differences of requirements in the reception of data;

• Shortcomings in the relay of the data on the GTS;

• Data not monitored:

• Differences in the implementation of the monitoring procedures at centres.
