Five years of investigation of whistler-mode chorus using the measurements of the Cluster spacefleet
Original language description
We summarize results obtained during investigation of whistler-mode chorus emissions by the four Cluster pacecraft during their first five years of operation. The results can be divided into several broader categories. (i) Substructure of chorus wave packets have been observed at time scales of 1-40 ms, with decreasing occurrence rate for longer durations. Their growth rate is between 30 and 400 s-1, and amplitudes reach up to 30 mV/m or 300 nT in the disturbed times. Maximum amplitudes are inside the arger chorus wave packets which occur at time scales above 100 ms. (ii) Frequency differences have been observed for chorus wave packets which were simultaneously detected by different spacecraft. These differences have been interpreted as differential Doppler shift from rapidly moving elementary chorus sources at speeds comparable to the parallel velocity of counterstreaming resonant electrons.
