| Zusammenfassung |
| A new experimental technique is presented for the determination of the total
electron content (TEC) below a low-orbiting satellite. According to this
technique TEC can be obtained using the segment of a topside ionogram that
only contains the traces of signals reflected from the Earth's surface.
Possibilities of this technique were demonstrated using MIR station topside
sounding data at the night time for both quiet and disturbed ionospheric
conditions, and in particular, during the 14 November 1998 storm. An interesting
fact was revealed with the help of this technique: after a series of
relatively strong storms the main ionospheric trough on 14 November 1998 was
detected at an abnormally low geomagnetic latitude (~43°). During
this study some spatial variations of TEC were registered that can be
interpreted as a TID-type wave structure. |
