Ionosonde is the widely used instrument for ionosphere sounding.
The traditional ground-based vertical incidence sounding (ionosonde) measurements are sufficient for a precise determination of the bottom-side electron density profile.
In order to analyze pre-earthquake ionospheric anomalies, ionosonde and Global Navigation Satellite System (GNSS) data have generally used in most researches.
The ionospheric bottomside electron density profile was derived from ground-based observations using an ionosonde, digisonde, and incoherent scatter radar in the form of ionograms.
In order to validate the sources of these ionospheric echoes, concurrent ionogram observed by the Chung-Li ionosonde that is an instrument vertically transmitting a FM pulse with a frequency range of 0.5-30 MHz to exclusively detect the echoes from ionospheric layers and electron density irregularities is adopted for comparison.

Other examples of co-operative research are support of seismographic instrumentation, ionosondes through the Canadian High Arctic Ionospheric Network (CHAIN; Jayachandran et al., 2009), and logistical support for activities in support of the UN Convention on the Law of the Sea (UNCLOS).
The most important technique for ionospheric monitoring, makes use of a network of ionosondes which provides a measure of a number of ionospheric parameters for a discrete number of heights and frequencies.
