| Zusammenfassung |
The recent availability of substantial data
sets taken by the EISCAT Svalbard Radar allows several important tests to be
made on the determination of convection patterns from incoherent scatter radar
results. During one 30-h period, the Svalbard Radar made 15 min scans combining
local field aligned observations with two, low elevation positions selected to
intersect the two beams of the Common Programme Four experiment being
simultaneously conducted by the EISCAT VHF radar at Tromsø. The common volume
results from the two radars are compared. The plasma convection velocities
determined independently by the two radars are shown to agree very closely and
the combined three-dimensional velocity data used to test the common assumption
of negligible field-aligned flow in this regime.
