European EO data & model fusion (to maximise the value of ESA EO Data)
Alan O’Neill
National Centre for Earth Observation
Issues that have arisen
• Need to pull together science and applications.
• Emphasis on modelling and data assimilation.
• Need for monitoring.• Need for integration (e.g. Glob projects)• Need for infrastructure and support for
data access
Issues continued
• Support for re-analysis• Interface between data providers and
operational institutes.• Scattering of workforce• Difficulty of using in operations new,
interesting instruments• Value of synergy of observations• Need for validation systems
Issues continued
• Better Earth system approach
• Different levels of maturity of different disciplines in use of EO.
• GEMS as a model for European integration?

Synthesis via Assimilation of EO data into Earth System Model
What is needed?
• Greater co-ordination of data assimilation activities in Europe
• Structure that draws on the distributed strengths of the European science community
• A means to integrate scientific and technical advances in an Earth system simulator (s)
• A support structure that allows that integration to occur and to be sustained.
• The aim to focus on high-level data processing for science and end-users – providing useful information rather than data.
• The specific goal will be to set up a structure in Europe, marshalling the resources of the university community and of other institutions
The Concept
• To provide ESA (and thereby its customers) with the equivalent of NASA’s Data Assimilation Office, but in a cost-effective manner, by– building on existing national infrastructure– tying in closely with operational d.a. (unlike the
DAO)– entraining additional funds (e.g. from EU)
• Concept envisages a European-wide entity, pulling together existing consortia
The Concept
The Concept
• The structure has the following goals:– The deliver high-level products from innovative ESA
and other instruments to scientific end users– To deliver the science and technology needed by
GMES – To provide the bridge from ESA innovation to
operational implementation by tying in to “operational centres” (e.g. ECMWF and national weather centres) helping to convert today’s innovative, science-led instruments to tomorrow’s operational instruments – i.e. a parallel and supporting activity to operational exploitation of EO
The Concept
– A key and under-exploited feature of d.a. is its ability to test climate (and other environmental) models stringently. Model uncertainty is a key issue in international debate about climate change. This activity should be strongly emphasised.
– The structure could organise high-level training in EO science and applications.
– The structure would provide the critical mass and partnerships needed to achieve the ambitious vision of earth system monitoring and prediction
Current Situation in Europe & What is Still Needed
• European expertise front rank
• Efforts fragmented, short term, unable to build critical mass
• We need more than a loose collaboration, but an operation managed as a centre with clear objectives and firm deliverables.
Structural and Infrastructural Issues
• Exploit and enhance existing capabilities in computer power and infrastructure, e.g. national resources.
• New technology allows us to emulate the organisational structure of an actual centre.
• ECMWF might play a key role in operational integration.
• ECMWF might provide– Remote use of its d.a. system, supported by externally
funded staff at ECMWF– High-performance computing.
The Way Forward?
