| Description |
The Global Navigation Satellite System (GNSS) data, ionosonde data, magnetometer data, VHF radar echo and low latitude long range ionospheric radar (LARID) echo data are from the Ionospheric observational network for irregularity and scintillation in East/Southeast Asia (IONISE), the Chinese Meridian Project (http://data.meridianproject.ac.cn), the eSWua database (http://www.eswua.ingv.it/index.php), the Australian Space Weather Forecasting Center (https://www.sws.bom.gov.au/), the INTERMAGNET-British Geological Survey (https://imag-data.bgs.ac.uk/GIN_V1/), and the online global TEC database (https://stdb2.isee.nagoya-u.ac.jp/GPS/GPS-TEC/), and are archived at the Geophysics Center, National Earth System Science Data Center at BNOSE, IGGCAS (http://wdc.geophys.ac.cn/). Based on the GNSS data, the rate of total electron content (TEC) index (ROTI, computed for each 300-second interval and converted to the unit of TECu/min) with elevation angles lager than 30° were calculated. The ionosonde ionograms obtained at Mohe, Beijing, Wuhan, Ledong, Guam and Meiji, with temporal resolutions of 15 min, 15 min, 15 min, 7.5 min, 7.5 min and 5 min respectively were manually scaled to get the peak height of the ionospheric F2 layer and vertical plasma drift. The echoes from the phased-array VHF radar at Ledong and LARID at Dongfang are used to investigate the ionospheric irregularities associated with equatorial plasma bubbles. The VHF radar worked at a frequency of 47.5 MHz and a peak power of 72 kW. During the present experiment on 1 December 2023, the 4-bit complementary pulse code was used, with a repetition frequency of 200 Hz and coherent integration number of 4. The sampling range was 75-735 km, with a range resolution of 2.5 km. The LARID worked at 20.4 MHz under a beam steering mode within the azimuth -25°-0° (clockwise due boresight of east radar) and 0-25° (clockwise due boresight of west radar), stepped by 5°. For each beam, the number of range gates is 160 with range resolution of 60 km, attaining a maximum range of ~9600 km at each side. |
