Overview – Background
Ether is a project developed and funded by the French Space Agency (CNES) and the INSU/CNRS
– Ether is operational since November 2000
– Ether received the scientific evaluation approval in 2008
■ ObjectivesTo assist the scientific community to locate, access and interpret
atmospheric chemistry dataTo provide data processing software and toolsTo insure an efficient scientific expertise on data and softwareTo provide information about the data collectionTo collect and answer to the users’ needs

Overview – Structure & organization
■ Two technical components
The Ether Data Centre performs systematic production, provides data, users assistance, archiving, a first level expertise on data and software, algorithms definition and development
The team is composed of 4 people with a manager It is located in the University Paris 6 It is equipped with 11 computers;
1 antenna for the IASI data reception through EUMETCAST
The scientific expertise network (several Scientific Expertise Centers) performs conception, validation and expertise on data, models and software and if needed production data
It is located in various French research organisms For each activity there is a scientist leader It provides data, models and software to the Ether Data Centre
The link between the two entities is assumed by the project manager

Europeans activities
■ GEOMON (Global Earth Observation and Monitoring of the atmosphere)
Ether produces outreach web pages, it provides also data profiles extracted from MIMOSA and REPROBUS fields
■ IAGOS (Integration of in-situ Aircraft measurements into a Global Observing System)
Adaptation of the MOZAIC data base
■ GEMS/MACC (Monitoring Atmospheric Composition And Climate)
Ether provides IASI data and processing facilities to the French team (C. Clerbaux LATMOS) responsible of the production of IASI CO data
Access and scientific expertise (from the LATMOS and the LA ECCAD and scientific data IAGOS)
Ether is involved in 3 Europeans projects (GMES Atmospheric Service)

Conclusion
■ Summary Ether was built in a logic of evolution Ether collects a great quantity of very diversified data This large variety allows the inter-comparison and validation of the data Ether maintain the data processing up to date Ether define common tools for the common needs of the users Thanks to the permanent call for tender, the Ether centre is in constant evolution always
more close to the needs for its users
■ Perspectives To define the standards necessary to the inter-working of the thematic centre in the
concern for conservation of the data To take part in the definition of the format of compression of the chemistry atmospheric
data To continue the adaptation to the evolutions in particular for the access to
the bulky data
