Cover Story: Atmospheric gravity waves (GWs) are believed to be the seeding mechanism for the occurrence of equatorial ionospheric irregularities; however, it was not known which range of the waves are responsible for the occurrence of the irregularity. In this study, the wavelengths of the GWs responsible for seeding the irregularity are identified using the TIMED/SABER and C/NOFS satellites’ observations. The results showed that GWs with vertical wavelengths (VWs) between about 1 and 13 km are found to dissipate energy in the Earth’s lower thermosphere every day. The zonal wavelengths estimated to correspond to these GWs and the oscillation of ion density perturbations have shown excellent agreement. In general, the results imply that GWs with VWs between 1 and 13 km are seeding the post-sunset equatorial ionospheric irregularity. View this paper
