| Zusammenfassung |
| Whistler-mode chorus waves are receiving increased scientific attention due to their
important roles in both acceleration and loss processes of radiation belt electrons. A global
survey of whistler-mode chorus waves is performed using filter bank data of wave magnetic
field from the THEMIS spacecraft with 5 probes in near-equatorial orbits. Our results confirm
earlier analyses of strong dependence of wave amplitudes on geomagnetic activity,
confinement of nightside emissions to lower magnetic latitudes, and extension of dayside
emissions to higher latitudes. An important new finding is the higher occurrence rate of
chorus on the dayside at 7< L |
