Matchup database
The GHRSST Match-up Database (MDB) of co-located satellite and in situ SST is a service of Medspiration project funded by ESA. It is required by GHRSST for quality control of satellite SST datasets, in particular for deriving or verifying SSES using in situ SST observations from ships, buoys and profiling floats. Such observations provide a reliable independent reference data set that must be matched in space and time to satellite observations.
Although several independent MDB systems have previously been created by agencies responsible for particular SST products, their formats are diverse, their in situ data sources may be different, and they do not share uniform quality control and spatial/temporal match-up criteria. These important differences make it difficult to compare MDB analyses of different SST products with each other. The GHRSST-MDB is intended to remedy this. It is a new multi-sensor SST MDB being developed at the IFREMER centre in Brest, France by integrating in situ data held within the Coriolis system (responsible for the collection and archiving of global in situ oceanographic data, http://www.coriolis.eu.org) and an archive of GHRSST data products, both hosted by IFREMER.
