Match-up Database Facility
The Match-up Database Facility (MDB-F) is a service implemented and hosted at Ifremer/Cersat in the context of GHRSST project. It offers to sea surface temperature (SST) providers a portal where they can provide and deliver their co-located satellite and in situ SST datasets (or match-up databases) and to users a way of selecting and accessing these match-ups either interactively or through ftp. It is required by GHRSST as a critical tool to assess the quality of satellite SST datasets, in particular for deriving or verifying sensor's specific errors using in situ SST observations from ships, buoys and profiling floats. Such observations provide indeed a reliable independent reference data set that must be matched in space and time to satellite observations.
