Quality controlled maritime meteorological observations
Mqc data files contain all worldwide weather reports of the Voluntary Observing Ships (VOS) that are internationally exchanged via the Voluntary Observing Ship Global Data Assembly Centres (VOS-GDACs) on a quarterly basis. This delayed mode data is checked according to the Minimum Quality Control Standard (MQCS) and provided with quality control indicators, the flags.
The data format is International Maritime Meteorological Tape (IMMT) and from 2010 on also International Maritime Meteorological Archive (IMMA).

The files contain all worldwide weather records of the Voluntary Observing Ships (VOS) that are internationally exchanged via the VOS-GDACs on a quarterly basis. The delayed mode data is checked according to the Minimum Quality Control Standard (MQCS) and provided with quality control indicators, so-called flags. The format is IMMT and from 2010 also IMMA.

Since 1964, the World Meteorological Organization (WMO) regulates the international collection of meteorological data on the world's oceans done by ship crews. The WMO also manages the quality control, distribution and archiving of these observations. To improve the processing of observation data and to standardize the quality control, two Global Collecting Centres (GCCs) were founded in 1993: GCC-Germany in Hamburg (DWD) and GCC-UK in Edinburgh (Met Office). In 2017 the Marine Climate Data System (MCDS) was established by the former Joint WMO-IOC Technical Commission for Oceanography and Marine Meteorology (JCOMM). The MCDS coordinates the activities of maritime meteorological and oceanographic data systems, and since 2019 the former GCCs are working as Voluntary Observing Ship Global Data Assembly Centres (VOS-GDACs) in this new system.
Port Meteorological Officers (PMOs) collect global data stored on the ships and carry out a standardized minimum quality control (MQCS). Data is forwarded to the VOS-GDACs. The VOS-GDACs verify that quality control is carried out properly, support countries in case of issues with data supply or quality control, archive the data and make them available for download in CDC on a quarterly basis. The regular data exchange is done since 1996. The oldest observations date back to 1982.
