The Tasks of the GCCs
GCCs ensure, that WMO agreed Minimum QC Standards are applied and feed back results to CM
All data received by GCCs is distributed to 8 RMs quarterly
VOSClim ship data is submitted to DAC
At the year end a ‘GCC Annual Report’ is published highlighting GCCs work and data received
GCCs provide advice/support to CMs
