Electron Density vs Field Line Distance
Date: 07 November 2006
Depicts: Electron density derived from WHISPER data
Electron density derived from Cluster/WHISPER spectrograms as a function of Requat (geocentric distance of the field line on which the observation is made, measured at the magnetic equator) for the plume crossings on 2 June 2002. The lower four curves correspond to the inbound pass and the upper four curves (shifted by a factor 10) to the outbound pass. The magnitude of the normal boundary velocity VN-eq derived from the time delays of different features and projected onto the magnetic equatorial plane is indicated.
