WMO Publication No. 9, Volume A, Observing Stations 

and WMO Catalogue of Radiosondes

Volume A contains a complete list of all the surface and upper-air stations in operation, which are used for synoptic purposes.  The contents are arranged in the order of the WMO Regions and in index number order within each Region.  The regional sections are followed by sections containing stations in the Antarctic and Ocean Weather Stations.

The Volume A modification to accommodate station coordinates with higher precision was developed following the recommendation of CBS-EXT. (06) and approval of EC-LIX. The Secretariat released a Letter of notification of the revised changes to Members with a request for updated information of their stations in accordance to the new specifications.
