GPS Ionospheric mapping and tomography: A case of study in a geomagnetic storm [PDF]
, 2011 The ionosphere has been normally detected by traditional instruments, such as ionosonde, scatter radars, topside sounders onboard satellites and in situ rocket. However, most instruments are expensive and also restricted to either the bottomside ionosphere or the lower part of the topside ionosphere (usually lower than 800 km), such as ground based ...

Comparison of travelling ionospheric disturbance measurements with thermosphere/ionosphere model results [PDF]
Annales Geophysicae, 2003 Comparisons of modeled and measured responses of the ionosphere to the passage of atmospheric gravity waves are made for data recorded by an ionosonde located at Almaty (76°55' E, 43°15' N) from June 2000 until May 2001.

A new inversion algorithm for backscatter ionogram and its experimental validation [PDF]
Annales Geophysicae, 2014 Oblique backscatter sounding is a powerful tool for detecting and monitoring the ionosphere continuously at a remote distance. High-frequency (HF) backscatter ionograms provide the amplitudes of backscatter signals with respect to group path or time ...
