• Entries to the GHRSST-PP diagnostic data set (DDS) will be compiled by extracting,<br />
and resampling onto a 0.01º grid, full resolution sub scenes for a set of predefined<br />
small areas (typically 2º × 2º) from every L2P SST and L4 dataset generated by the<br />
<strong>Medspiration</strong> processor. The DDS sites are defined by GHRSST-PP. The purpose<br />
of the DDS is to allow intercomparison of the characteristics of the SST derived from<br />
different sensor types, in order to facilitate the research needed to test and improve<br />
the data merging methods used in GHRSST-PP.<br />
2.2 Overall structure of the <strong>Medspiration</strong> Processing <strong>System</strong><br />
Figure 2-4 outlines schematically the main processing tasks required to produce the four<br />
types of SST products described in 2.1.2. The figure shows the main classes of inputs<br />
and outputs, and assigns distinct processing stages to different boxes. The whole<br />
system is distributed across the facilities of three contractors, CMS, Ifremer and SOC, as<br />
indicated in the figure.<br />
The underlying data flow through the system is basically simple. Level 2 SST data<br />
products generated from different sensors and produced by the mission ground segment<br />
or agency responsible for each are obtained by Internet and ingested into the first main<br />
processing centre. This is hosted in CMS where use will be made of the fact that CMS is<br />
already an operational provider of processed AVHRR data, which is a key SST input<br />
stream for the L2P product. Consequently one of the major sources of input data will be<br />
provided internally. At the same time the CMS processing facility will ingest auxiliary<br />
satellite data, such as wind speed, needed for the quality assessment. The SSES,<br />
reference data fields and any other necessary information will be supplied by the<br />
