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.
