Abstract: We analyzed the horizontal phase velocity of gravity waves and medium-scale traveling ionospheric disturbances (MSTIDs) by using the three-dimensional fast Fourier transform method developed by Matsuda et al. [2014] for 557.7-nm (altitude: 90–100 km) and 630.0-nm (altitude:… read more here.
