- The Cluster Science Data System (CSDS) is an integral part of ESA's Cluster Mission to the Earth's magnetosphere.
Since Cluster consists of 11 different experiments, each one managed by a separate Principal Investigator and his/her team, the problem of data exchange among the experimenter groups is not a trivial one. High-quality, fully validated data is something that each team wishes to keep under strict control in order to avoid misuse and misinterpretations. On the other hand, rapid data exchange among the teams is vital for a complete understanding of the complex processes to be studied by Cluster; each team needs the data from the others to properly analyse its own. (See the text from the Final Report of the CSDS Working Group.)
To fulfill this requirement, the Cluster Science Working Team together with the Cluster Project have established CSDS, a distributed set of data centres, most of which are associated with one or more of the Cluster experiments. With software provided by the experiment team, each data centre processes the data for "its" experiments, and then exchanges them with all the other centres to obtain a full set in a standard format. See the CSDS Ring for the data centres.
