Create a Master Metadata Repository Data Set Description (MMR_DSD) record within the GHRSST-PP MMR for each data stream described in Appendix A3. ING.0030 MDB.0530 40 WP1-026 3. Evaluate each data files for integrity when ingested at an RDAC or GDAC facility. ING.0060 CTR.0120 CTR.0110 40 WP1-027 4. Determine if the data file should be accepted into the GDS. If not, then raise an error report and send this to the data provider and to the GDS ERRLOG. QLC.0010 EXT.ING.0030 40 WP1-028 5. Rename the data file by prefixing the RDAC identification code to the filename. ING.0040 40 WP1-029 Each sub task is described in the following sections. NASR 40 F4.1 WP1-030 Figure 4.1 Functional breakdown of GDS WP-ID1 identifying each sub task. NASR 41 WP-ID1.1.1 Access to input data streams 41 WP1-031 The GDS does not consider L0, L1a or L1B data streams (although L1B data streams may be available for certain HR- NASR DDS sites if RDAC are able to supply these data). 41 WP1-032 Satellite SST, auxiliary satellite data (including wind speed and surface solar irradiance (SSI)), in situ observations and L2P.0010 NWP data are all required by the GDS to construct L2P data products and to produce L4 analysed SST data product outputs. 41 WP1-033 Satellite data are ingested at RDAC and in some cases at GDAC centres. L2P.0010 41 WP1-034 Each data stream will be formatted according to a well specified format provided by each data provider. format 41 WP1-035 Note that data streams from the same sensor may have different formats depending on the data provider. format 41 WP1-036 Table 4.1 provides an overview of the data sets that are available to the GHRSST-PP during the period 2003-2007 categorised by data type.

Medspiration MED-SOC-RS-001_1 System Requirements Document Issue F Page Table, fig. Reference ID Text from reference documents 41 T4.1 WP1-037 Table 4.1 Real Time global and regional satellite and in situ data streams available to the GHRSST-PP during the period SR entry NASR 2003-2007. In situ data streams are those providing data within the upper 8 m of the water column. Acronym definitions are given in Appendix A2 Table A2.2. 42 WP1-038 Appendix A3 describes in detail the data that will be used by the GDS. Appendix A3.1 defines the satellite SST data NASR streams, Appendix A3.2 the auxiliary satellite data streams, Appendix A3.3 the in situ data streams and Appendix A3.4 the NWP/Forecast fields. 42 WP1-039 A unique identification code for each data stream is given in Appendix A3 that will be referred to throughout the GDS. NASR 42 WP1-040 Also specified are the general characteristics of each data stream including the data provider, data delivery mechanism, NASR any data agreement that is applicable together with the primary and secondary RDAC/GDAC entry points. 42 WP1-041 All of this information will be used by the GHRSST-PO and the GHRSST-PP Data management sub-group to generate NASR MMR_DSD records for each data stream that is used by the GDS according to the specifications provided in Appendix A6 Table A6.2.1. 42 WP-ID1.1.2 Preparation of Master Metadata Repository (MMR) data set description records (MMR_DSD) 42 WP1-042 The data streams within the GDS are dynamic in the sense that new data sets will become available, certain data sets may NASR take priority in given circumstances (e.g., aerosol contamination) and regional preferences based on the ease of data access will exist at RDAC. 42 WP1-043 The GHRSST-PP Master Metadata Repository (MMR) is an online dynamic database that contains a metadata record for NASR every data file that is produced by the GHRSST-PP. It provides a major source of information for RDAC and GDAC describing the availability of data files at any given instant in time. It also provides a catalogue for the GHRSST-PP archive. 42 WP1-044 The GHRSST-PP MMR system and the format of MMR_DSR and associated MMR File Records (MMR_FR), ING.0050 implementation of the MMR and delivery of MMR data records by RDAC and GDAC is described in Appendix A6. © 2004 SOC Page 129 of 193
