The provision of marine weather services is an important function of the national meteorological services of coastal and maritime nations — including the Met Office. As well as forecasts the Met Office plays a major role in providing observations of weather at sea.
Under the Joint WMO/IOC Technical Commission for Oceanography and Marine Meteorology (JCOMM), intergovernmental body of experts, which provides the international co-ordination, regulation and management of marine meteorological services, the Met Office runs one of two Global Collecting Centres (GCCs). The GCC is run as part of the World Meteorological Organization's (WMO) Marine Meteorology Programme.
The aim of the Global Collecting Centre is to ensure that marine data are received from contributing members around the world and processed to an agreed standard. The data are then distributed on a quarterly basis to eight responsible members, each with their own area of responsibility.
41 contributing members as of 2002
These eight members are:
At the end of each year the GCC Annual Report is published. This details data received and processed over the past year and also any new developments and future plans within the MCSS (Marine Climatological Summaries Scheme).

At JCOMM-III in Marrakech, November 2009, the updated IMMT-4 format was adopted for general use from 1 January 2011. This is now the preferred format for delayed mode observations and includes the capability to record the new ship (VOS) classes as well as relative humidity as a separate element.
The International Maritime Meteorological Tape (IMMT) format, for the exchange of delayed-mode observations, is now in its 4th version: IMMT-4 (PDF, 75 kB)
The Minimum Quality Control Standards (MQCS) are now in their 6th version: MQCS-6 (PDF, 104 kB)
Consolidated MQC for Contributing Member software version 4 is now available from the World Meteorological Organization.
