| Zusammenfassung |
| Various types of plasma waves have profound effects on acceleration
and scattering of radiation belt particles. For the purposes of
radiation belt modeling it is necessary to know statistical
distributions of plasma wave parameters. This paper analyzes four
years of plasma wave observations in the Earth's outer radiation
belt obtained by the STAFF-SA experiment on board Cluster
spacecraft. Statistical distributions of spectral density of
different plasma waves observed in ELF-VLF range (chorus,
plasmaspheric hiss, magnetosonic waves) are presented as a function
of magnetospheric coordinates and geomagnetic activity indices.
Comparison with other spacecraft studies supports some earlier
conclusions about the distribution of chorus and hiss waves and
helps to remove the long-term controversy regarding the distribution
of equatorial magnetosonic waves. This study represents a step
towards the development of multi-spacecraft database of plasma wave
activity in radiation belts. |
