| Description | The Global Navigation Satellite System (GNSS) data airglow imager and ionosonde data are from the Ionospheric Observational Network for Irregularity and Scintillation in East/Southeast Asia (IONISE), the Indonesia Continuously Operating Reference Station (Ina-CORS), and the International GNSS Service (IGS). ROTI (the Rate of Total Electron Content index) was computed for each 5‑min interval in units of TECu/min. Airglow images were recorded by the Keo Sentry3 airglow imager at Meiji. The ionosonde ionograms obtained at Meiji, with a temporal resolution of 15 min, were manually scaled using SAOExplorer to derive the virtual height. LARID HF radar observations were conducted at Dongfang station (108.8°E, 19.2°N). Optical interferometer data at Fuke were downloaded from the Meridian Project Data Center. |

| Type | TEC and ROTI data include UT (hour), Ipplat (latitude at the ionospheric piercing point), Ipplon (longitude at the ionospheric piercing point), and Elevation (elevation angle of the receiver–satellite path at the receiver station). TEC (total electron content) is provided at 30‑s intervals, and ROTI (rate of total electron content index) is provided at 5‑min intervals. LARID data include SNR (signal‑to‑noise ratio of LARID echoes) and Doppler velocity (Doppler velocity of LARID echoes). Airglow data are provided as grayscale images (PNG format). Ionosonde virtual height data include UT and virtual height from 3 MHz to 9 MHz. Optical interferometer data include UT and winds at five beams: vertical (Z), north (N), south (S), east (E), and west (W). |
