| Zusammenfassung |
| Space weather applications require real-time data and wide area observations
from both ground- and space-based instrumentation. From space, the global
navigation satellite system - GPS - is an important tool. From the ground
the incoherent scatter (IS) radar technique permits a direct measurement up
to the topside region, while ionosondes give good measurements of the lower
part of the ionosphere. An important issue is the intercalibration of these
various instruments.
In this paper, we address the intercomparison of the EISCAT IS radar and
two ionosondes located at Tromsø (Norway), at times when GPS measurements
were also available. We show that even EISCAT data calibrated using
ionosonde data can lead to different values of total electron content (TEC)
when compared to that obtained from GPS. |
