Ionospheric disturbances triggered by SpaceX rocket launches

In this presentation, ionospheric disturbances triggered by recent SpaceX rocket launches are examined using dense ground based GNSS receivers. There are disturbances in the ionosphere showing acoustic wave and gravity wave characteristics for various type of the rocket launches during the rocket flight stages. We observe V- or circular shape of rocket induced shock waves followed by concentric or ducted gravity waves. Some of the acoustic waves show long period oscillations with the period close to the gravity wave period. Meanwhile, some of the gravity waves have short periods that are close to the acoustic waves. The numerical simulations using whole atmosphere and ionosphere models are also performed to identify the relevant physics.
