WBD data were successfully obtained during the mission commissioning period from September 2000 through January 2001. These data were obtained by direct real time downlink to a NASA Deep Space Network antenna and by onboard recording in the Burst Mode 2 (BM2) mode. During these four months when WBD data were being obtained, the instrument was primarily cycling through all of its various modes and options (bandwidths, conversion frequencies, electric or magnetic antennas, resolutions). The times when data were obtained and the modes in which they were obtained can be found in the WBD Coverages files for these four months, available through this website under Data & Tools, or by following this link: Data Coverage
Most of WBD data obtained during the commisioning period were considered of good science quality and thus were archived. This includes all of the BM2 data obtained during the four-month period as well as the real time DSN data obtained on November 27, 2000, December 10, 21, and 22, 2000, and all of January 2001. We note that several scientific papers were written on the data obtained on November 27, 2000, which contained chorus waves observed simultaneously for the first time on three of the four Cluster satellites.
All commissioning data that were calibrated and archived can be accessed from the Cluster Science Archive and NASA's CDAWeb as CDF files. Please refer to this website's Data Archives under Data & Tools for the links to access these files or use this direct link: Data Archives
. Also refer to this website's Survey Plots under Data & Tools to peruse survey spectrograms as well as 30-second and 10-minute gif plots of all data intervals that were archived or use this direct link: Survey Plots. Thirty-second gif plots of all other commissioning data intervals not archived can be accessed through these links, separately by spacecraft:
