Interpretation of ionospheric F-region structures in the vicinity of ionisation troughs observed by satellite radio tomography
Tomographic images of the spatial distribution of electron density in the ionospheric F-region are presented from the Russian-American Tomography Experiment (RATE) in November 1993 as well as from campaigns carried out in northern Scandinavia in November 1995 and in Russia in April 1990. The rec...

| Summary: | Tomographic images of the
spatial distribution of electron density in the ionospheric F-region are
presented from the Russian-American Tomography Experiment (RATE) in November
1993 as well as from campaigns carried out in northern Scandinavia in November
1995 and in Russia in April 1990. The reconstructions selected display the
ionisation troughs above the tomographic chains of receivers during
geomagnetically quiet and disturbed periods. Two mathematical models of the
high-latitude ionosphere developed in the Polar Geophysical Institute have been
applied for interpretation of the observed tomographic images.<br><br><b>Key words. </b>Ionosphere (electric fields and currents;
