A new Doppler type system for measuring the ionospheric effects of infrasound developed in the IAP.
Original language description
Various upward propagating waves seem to be the dominant component of the upward coupling of the lower and middle atmosphere to the upper atmosphere and ionosphere, even though there is also an electromagnetic coupling via electromagnetic waves, global electrical circuit, sprites and other phenomena. The waves propagating upward from below in theneutral atmosphere at middle latitudes are basically planetary waves (periods of days to a few weeks), tidal waves (periods of 24-, 12-, 8- and 6-hours), gravity waves (periods of several minutes to several hours) and infrasound waves (periods between about 0.1-100 seconds). A new Doppler type system has been developed primarily to measure the ionospheric effects of infrasound. Such effects have very little been studied compared to ionospheric effects of othertypes of longer-period waves; they might be of special interest to the radio channel propagation community in COST271.
