To ensure the data exchange between the Cluster experimenters and with other space missions, the Cluster Science Data System (CSDS), a decentralized system, was established. The backbone of this system are six data centers in Europe: MPE (Max Planck Institute for Extraterrestial Physics), Garching, Germany, RAL (Rutherford Appleton Laboratory), near Oxford, England, KFKI (Central Research Institute for Physics), Budapest, Hungary, CNES (Centre National d'Etudes Spatiales), Toulouse, France, KTH (Royal Institute of Technology) Stockholm, Sweden, and IWF (Space Research Institute), Graz, Austria, supplemented by JSOC (Joint Science Operation Centre), near Oxford, England and ESOC (European Space Operation Centre), Darmstadt, Germany.
The Austrian Cluster Data Center (ACDC) is operated by the Space Research Institute (IWF) of the Austrian Academy of Sciences (AAS) in Graz. The data centers are connected via a virtual network, the so-called CSDSNet. There are two additional, non-European data centers, one in the USA and one in China. Owing to the lack of a reliable network connection the Chinese Data Centre is supplied with the Cluster data by the ACDC, where the data is copied to CD-ROMs, which are sent to China regularly. A standardized graphical user interface, the so-called Cluster Data Management System (CDMS), and software for the various tasks of the CSDS have been jointly developed. ACDC is responsible for the processing of the ASPOC raw data from the four Cluster spacecraft and it holds an archive of the Cluster raw data. The installation and operation of a CDMS web server provide data access for the Austrian science community.
