  "x_description": "This dataset contains preliminary spin resolution measurements of the density, bulk velocity, parallel and perpendicular temperatures of protons and ions at the satellite in three dimensions from the CIS COmposition Distribution Analyser and Hot Ion Analyser experiments on the Cluster C1 spacecraft. These data have been converted into Cluster Exchange Format from the original Cluster Science Data System Common Data Format (CDF) Prime Parameter files that were made available through the Cluster Science Data System. The metadata has been updated from the CSDS/CDF standard to the CAA to aid compatibility with tools developed for the Cluster Science Archive. _ Version 01 of this dataset is the initial translation prepared for the launch of the CAA during the second half of 2005.",
