A FORMOSAT-5 (FS-5) satellite was launched on 25 August 2017 CST into a 98.28° inclination sun-synchronous circular orbit at 720 km altitude along the 1030/2230 local time sectors.  Advanced Ionospheric Probe (AIP), a piggyback science payload developed by National Central University for the FORMOSAT-5 satellite, has measured in-situ ionospheric plasma concentrations at a 1,024 Hz sampling rate over a wide range of spatial scales for more than 7 years.  Dramatical ionospheric plasma density and velocity modulation caused by natural hazards like 2022 Hunga Tonga–Hunga Haʻapai eruption and 2024 Mother Day geomagnetic storm had been observed clearly by FS-5/AIP and will be presented in the talk.
