9 http://www.ghrsst-pp.org Group for High Resolution Sea Surface Temperature GDS as a system The GDS is meant to describe a complete end to end system Anyone should be able to read the GDS and implement a component GDS Components include –Products (L2, L3 & L4) and user support tools (e.g read code) –LTSRF –GDAC –MMR –RDAC –MDB + SSES –HRDDS –GMPE –GDMS (GHRSST Dashboard and Monitoring System)

10 http://www.ghrsst-pp.org Group for High Resolution Sea Surface Temperature WE NEED OPERATIONAL MESSAGING (ERRLOG, OPLOG of GDSv1.0) Last LOG Last ERROR Contact GHRSST Operations Dashboard GDMS (GHRSST Dashboard and Monitoring System)

11 http://www.ghrsst-pp.org Group for High Resolution Sea Surface Temperature Products L2P (Swath native, netCDF) L3P (Gridded, netCDF) L4 (Analysed, netCDF) L4+ GMPE (Multiple analysed, netCDF) –Also suitable for RAN? HR-DDS (L3P subset?) MDB (specific, time/location aggregated?) MMR (Standards based ISO19115, ISPIRE, FGDC)
