Author ProfileAbstract
The 15 January 2022 eruption of the Hunga volcano provides a unique
opportunity to study the reaction of the ionosphere to large explosive
events. In particular, this event allows us to study the global
propagation of travelling ionospheric disturbances using various
instruments. We focus on the detection of the ionospheric disturbances
caused by this eruption over Europe, where dense networks of both
ionosondes and GNSS receivers are available. This event took place on
the day of a geomagnetic storm. We show how data from different
instruments and from different observatories can be combined to clearly
distinguish the TIDs produced by the eruption from those caused by
concurrent geomagnetic activity. By comparing observations obtained from
multiple types of instruments, we also show that TIDs produced by
various mechanisms are present simultaneously, with different types of
waves affecting different physical quantities.
