| Zusammenfassung |
| Single spacecraft measurements from the Cluster 3 satellite are used to
identify nonlinear processes in ion-sound turbulence observed within the
front of the quasiperpendicular terrestrial bow shock. Ion sound waves
possess spatial scales that are too small for the efficient use of multipoint
measurements on inter-satellite separation scales. However, it is shown how
frequency domain modelling can be applied to single spacecraft electric field
data obtained using the EFW internal burst mode. The resulting
characteristics of the nonlinear processes are used to argue about the
possible wave sources and investigate their dynamics. |
