| Zusammenfassung |
Results are shown from an experimental
campaign where satellite scintillation was observed at three sites at high
latitudes and, simultaneously, the F region plasma flow was measured by the
nearby EISCAT incoherent scatter radar. The anisotropy parameters of
field-aligned irregularities are determined from amplitude scintillation using a
method based on the variance of the relative logarithmic amplitude. The
orientation of the anisotropy in a plane perpendicular to the geomagnetic field
is compared with the direction of F region plasma flow. The results indicate
that in most cases a good agreement between the two directions is obtained.
Key words: Ionosphere (auroral
ionosphere; ionospheric irregularities) |
