Sea Surface Temperature

Defining sea surface temperature
How is sea surface temperature defined? They are in fact many definitions, often related to a particular type of sensing (and consequently depth of measurement). GHRSST-PP project has reached - after many years and many debates! - some kind of consensus on this topic that can be summarized as described here.
Overview Coriolis performs the collection of in situ data from various sources (drifting buoys, oats, ship data,...) received through various networks with various delivery delays (from real-time - less than 24 hours - to delayed mode - a few weeks or months later). These data are received and quality-controlled in real-time (and possibly with additional visual control from an operator) by Coriolis and then ingested and stored into a relational…
In situ measurements are used as truth values to assess and monitor the quality of satellites products. Various sources of in situ sea surface temperature data (ships, drifting buoys, Argo floats,...) are available in near real-time or delayed mode and can be used for that purpose. They are collected by CERSAT from Coriolis data center, quality controlled and formatted to a more easy to use for direct comparison with satellite…
This sections describes the content of the GHRSST match-up database, in particular its temporal extent for each GHRSST L2 products and the distribution of the match-ups with respect to the type of in situ measurement platform. This page is updated every month.
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…
This web application, which just requires a web browser with Flash plugin, allows users to select and extract match-ups from the GHRSST MDBs and to compute and display dynamic statistics based on satellite to in situ comparisons, using a large set of filters, flags and plot types. It was implemented using the Adobe/Flex technology which offers a powerful language for the development of Rich Internet Applications (RIA).
