Using Ionosondes for Lower‐Ionosphere Remote Sensing

Geophysical Research Letters
AbstractIonosondes are primarily used to measure the electron densities of the ionosphere's E and F‐region via frequency‐range analysis of the probing signal returns. The amplitude of the returning signal has often been ignored, however, and may allow estimates of other propagation effects such as D and E‐region absorption.

Observation of daytime medium-scale traveling ionospheric disturbances using GNSS systems

Учёные записки Казанского университета: Серия Физико-математические науки, 2018
The paper considers the problems of detecting midlatitude MSTIDs with a low intensity of disturbance ∆N/N using the method of transionospheric sounding with GNSS signals.

Evaluation of GNSS-TEC Data-Driven IRI-2016 Model for Electron Density

Atmosphere
The ionosphere is one of the important error sources that affect the communication of radio signals. The international reference ionosphere (IRI) model is a commonly used model to describe ionospheric parameters.
