The widespread use of Medspiration data accessed through the GDAC reported by Ed Armstrong of JPL

The use of Medspiration data in research by the US MISST projectSeveral international applications of Medspiration data reported by

Craig Donlon John Stark reported that Medspiration is indispensable for the OSTIA

L4 analysis NASA now use OSTIA data as a resource in their SPORT web site. The UK Met Office based last year’s winter long term forecast on Atlantic

upper ocean temperatures and SST expressed in OSTIA

Jacob Høyer reported that DMI rely on Medspiration L2P input for Daily Baltic & North Sea SST analysis product, which is used to set up

the operational high resolution NWP system specialist L4 analysis product for ocean regions following the progress of

a high profile round-the-world Danish educational expedition

AATSR L2P data used routinely to provide bias correction for all other SST data sources

CNR (Lia Santoleri) producing daily 4 km resolution L4 products for the Mediterranean., and this will become operational within MOON.

Rosa Barciella reported on assimilation of Medspiration L2P in FOAM reduces RMS by 0.1K, not only at the surface but down to 600 m depth. Will go operational in 2007

The GMES Marine Core Service MCSThe GMES Marine Core Service MCSThe GMES Marine Core Service MCSThe GMES Marine Core Service MCS What is the GMES MCS ?

A service to provide accurate estimates of the current ocean state using satellite and in situ data integrated with operational ocean models

A fast-track service for early implementation, to serve the needs of EU and national policy, management and monitoring requirements

The proposed Generic Mersea approach MERSEA - FP6 project tasked to design and develop the elements of the MCS The MCS Implementation Panel is drawing strongly on the framework proposed

by MERSEA, but expects a wider range of players to deliver the service A generic view of how satellite data will be fed into the European operational MCS

system:-



Generic tasks for the Thematic Generic tasks for the Thematic Assembly Centres (TACs)Assembly Centres (TACs)

Real-time additional processing of European level 2 data products generate a common data format and product standard, facilitating an

interoperable, harmonised data distribution system within the MCS.Near-real-time level 3/4 processing activities, generating analysis

products best estimate of an ocean property, blending data from various sources.

Providing access to all data products using real-time high volume data flow to the operational users, web access for general public users.

Delayed mode level 3/4 processing activities, e.g reanalyses for climate.

Quality control, validation and error characterization, Applied to products and forecasts produced within the TAC.

Interfacing with international activities for the same type of data, and with TACs for other data types including in situ data for validation.

Providing effective feedback on data products between users and the observing system

Some issues to noteSome issues to noteSome issues to noteSome issues to note

Primary validation the responsibility of the Space Agencies Requires in situ observations throughout the mission lifetime For Sentinel 3 validation must be fully budgeted in the mission

The EU-GDAC will archive all GHRSST SST products EU-GDAC = European Global Data Archive Centre The primary channel for European L2P and L4 products A mirror of the US-GDAC at JPL providing a portal for all SST data The long term stewardship and reanalysis facility (LTSRF) is provided by

NOAA and does not need duplicating in Europe

The EU-GDAC to monitor quality of all SST data Uses the Match-up database (MDB) and Diagnostic data set (DDS) to

validate the error estimates and quality flags of L2P data products MCS should provide this function for the world, since it is currently lacking

Reanalysis for climate records of SST – a task for MCS Should include reprocessing of level 2 datasets by the Space Agencies Needs to be co-ordinated with the international effort through the LTSRF



Is it achievable ? Is it achievable ? Is it achievable ? Is it achievable ? Most elements of proposed system are already developed

The GHRSST-PP concept has been proved The basic data systems are in place But present ESA support is for prototype development only Some key operational users already in place A producer – user feedback is already developed

A smooth transition to an operational system is possible Needs a secure funding line for operational stability Limited extra investment needed for secure 24/7 operation Limited further development effort required to operationalise the

quality feedback loop

The foundation is laid for an effective climate data system Can be based on the operational NRT processing system But needs a commitment to regular reprocessing and reanalysis



What should we do now?What should we do now?What should we do now?What should we do now?Ensure operational continuity is not broken

Request ESA maintains Medspiration until MCS is in place Unless GMES Office is willing to fund extension of Medspiration

Request ESA maintain the GHRSST-IPO

Maintain consensus in SST producer – user community Present a common view to the EU Obtain confirmation of user requirements for the Medspiration

Service to continue

Communicate to MCS-IG a generic outline of EU-GDAC Ensure L2P is implemented by the L2 SST producing agency Ensure that a full validation programme is in place for each

European SST sensor as part of its mission ground segment Explain how the EU GDAC plus the linked L2P & L4 production

fulfils the role of a TAC



Next stepsNext stepsNext stepsNext steps

Identify elements of the EU-GDAC requiring preparation Establish automated processes for the SSES verification loop to

be applied to all SST sensors as a GDAC function Define the concept of delayed mode L2P products

Produced within a few days when all ancillary data are available

Define the concept of the ”super-collated” L3(?) merged product Seek approval for DM-L2P and L3 collated at next GHRSST-ST

Prepare proposals for funding Scope out the actors and costs for operating EU-GDAC Co-ordinate & harmonise the diverse L4 product players for a

common proposal Strengthen the operational user involvement in management
