EDI Prime Parameter Data

After submitting a month and year through the above interface, your web browser will be directed to a page that contains zipped CDF files. You will have the option of downloading data for the entire month or individual days. In either case, each file contains CDF files for SC1, SC2, and SC3. CDF is the standard file format for the Cluster mission. It may be converted to ASCII using the QTRAN software available from Queen Mary, University of London, where one can also obtain the powerful QSAS plotting and analysis package. The Cluster Prime Parameter database begins with February 1, 2001. At this time, EDI PP data can be downloaded through December, 2005.

NOTES:

1. EDI processed data are obtained by combining multiple return-beams within each analysis interval, using either the triangulation or time-of-flight technique, to determine the drift velocity perpendicular to B. The data files contain both the drift velocity, and associated (-VxB) electric field, in inertial GSE coordinates (after subtracting the spacecraft velocity). The ground analysis provides a statistical assessment of the "quality" of each result, which we classify as "good", "caution", or "bad". The PP data available here were processed using a single spin (4 second) analysis interval, and have been filtered to retain only "good" results. The assignment of "good" is based on an automated algorithm, and should not be taken as a guarantee of each point. In some instances improved results can be obtained with manual adjustments to the filtering, analysis intervals, or processing parameters.
