CEOS WGISS mai Overview – Web site

CEOS WGISS mai 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 )

CEOS WGISS mai 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
