Vertical Structural Evolution of Ionospheric Holes Triggered by Rocket Launches Observed by the Sanya Incoherent Scatter Radar

Year: 2024
Type: article
Abstract: This article presents observational results of the vertical structural evolution of ionospheric holes during two rocket launches. A combination of observations from the newly built Sanya incoherent scatter radar (SYISR) and Global Navigation Satellite System networks was employed. The vertical structural evolution of two rocket‐induced ionospheric holes over the SYISR could be divided into three stages. Firstly, 10–11 min after launch, the holes initially appeared in the topside ionosphere. Then, the holes expanded rapidly toward higher and lower altitudes. At ∼30 min after launch, the holes extended to an altitudinal range of ∼200 km to over 700 km. The maximum depletion altitude was 425 km for the afternoon event and 283 km for the midnight event. Finally, the holes recovered slowly, with faster recovery at higher altitudes. Our work contributes to further understanding the vertical structural evolutionary mechanisms of the ionospheric holes and relevant ionospheric processes.
