On the other hand, CDS cannot determine the height of observation. It is therefore useful to combine measurements by CDS and by a nearby ionospheric sounder that can be used to estimate the reflection height of the CDS. Examples of analysis and detection of various ionospheric disturbances such as medium scale travelling ionospheric disturbances caused by gravity waves or infrasound, sudden ionospheric disturbances caused by solar flares or movement of ionospheric plasma induced by electric fields associated with sudden storm commencements and geomagnetic activity will be presented.
