| Zusammenfassung |
| Incoherent-scatter radar and ionospheric
sounding are powerful and complementary techniques in the study of the Earth's
ionosphere. The work presented here involves the use of the Tromsø Dynasonde as
a correlative diagnostic with the EISCAT incoherent-scatter radar. A comparison
of electron-density profiles shows how a Dynasonde can be used to calibrate an
incoherent-scatter radar and to monitor changes in the system. Skymaps of the
direction of Dynasonde echoes are compared with EISCAT-derived density profiles
to illustrate how a Dynasonde can be used to measure the drift velocity of
auroral features. Vector velocities fitted to Dynasonde echoes are compared with
EISCAT-derived plasma velocities. The results show good agreement when the data
are taken during quiet to moderately active conditions and averaged over time
scales of 30 min or more. |
