The Atmospheric Chemistry Ether Group: Expertise and Database

The Ether system has been developed in France in order to support scientific studies based on atmospheric chemistry. Ether is the focal point for French and foreign scientists for studying processes from the local to the global scales via the mesoscale, from the troposphere to the stratosphere, within a wide temporal range (from the minute to the decade). A huge variety of products is stored from ground-based, balloon-, air-, and space-borne measurements, to modelled and assimilated constituent fields, together with spectroscopic and kinetic rates data sets. In addition, the development of added-value services such as interactive graphic tools, extraction software, scientific ground-segments as for the Odin/SMR experiment and ancillary data production like potential vorticity fields, helps the efficient use of these heterogeneous products. Finally, information relative to the ongoing activities within the scientific community is presented on the Web site (http://ether.ipsl.jussieu.fr/).
