Modelling of the electron density height profiles in the mid-latitude ionospheric D-region

Annals of Geophysics, 1996
A new mid-latitude D-region (50-105 km) model of the electron density is presented obtained on the basis of a full wave theory and by a trial-and-error inversion method.

Modelling the spatial-temporal variability of the ionosphere over Turkey using a GPS network

, 2017
Ionosphere is an atmospheric layer that has a high electron concentration and anisotropic, dispersive, inhomogeneous nature. Total Electron Content (TEC) is one of the most important parameters that provides necessary information to observe the ...

Behaviour of quiet time ionospheric disturbances at African equatorial and midlatitude regions [PDF]

, 2018
Extreme ionospheric and geomagnetic disturbances affect technology adversely. Prestorm enhancements, considered a potential predictor of geomagnetic storms, occur during quiet conditions prior to geomagnetic disturbances.

DC electric field amplification in the mid-latitude ionosphere over seismically active faults [PDF]

Natural Hazards and Earth System Sciences, 2005
DC electric field in the ionosphere above seismically active regions can be formed in a process of external current insertion into the atmosphere-ionosphere electric circuit.

Driving the mid-latitude ionosphere from below: A statistical study using LOFAR

Journal of Space Weather and Space Climate
The Low Frequency Array (LOFAR) is one of the most advanced radio telescopes in the world. When radio waves from a distant astronomical source traverse the ionosphere, structures in this plasma affect the signal.

Evaluation of International Reference Ionosphere 2000 at a midlatitude station [PDF]

Radio Science, 2007
To check the validity of the latest version of the International Reference Ionosphere (IRI‐2000), which contains geomagnetic activity dependence based on an empirical storm time ionospheric correction (STORM model), comparison of measuredfoF2values with those obtained from the model was made.
