Description
| - In this case study we investigate the source region of whistler-mode chorus located close to the geomagnetic equator at a radial distance of 4.4 Earth radii. We use measurements from the four Cluster spacecraft at separations of less than a few hundreds of km, recorded during the geomagnetic storm of 18 April 2002. The waveforms of the electric field fluctuations were obtained by theWBD instruments in the frequency range 50 Hz-9.5 kHz. Using these data, we calculate linear and rank correlation coefficients of the frequency averaged power-spectral density measured by the different spacecraft. Those coefficients have been recently shown to decrease with spacecraft separation distance perpendicular to the static magnetic field (Santolík and Gurnett, 2003) with a characteristic scale length of 100 km. We find this characteristic scale varying between 60 and 200 km for different data intervals inside the source region.
