Description
Utilized here the images recorded by all-sky imager in 630.0 nm emission. The images are shown from S1 to S19, almost whole night data is shown with interval of 20 minutes.
Utilized Gadanki Ionospheric Radar Interferometer (GIRI) data taken from Gadanki (13.5°N, 79.2°E; 6.5°N Dip. Lat.), an off equatorial location of India on 22 March 2017. It works at both 30 MHz and 50 MHz frequencies which is essential to examine the bottom as well as topside irregularities of the ionosphere. Data plot is provided here in figure (S20).
Utilized here CADI data recorded from Tirunelveli (8.73°N, 77.7°E, 1.6°N Dip. Lat.) which is a dip equatorial station in India on 22-23 March 2017. It can be operated in both ionogram and drift modes. For the ionogram mode, the transmission of sounding frequencies is usually from 2 MHz to 16 MHz having resolution of few 100 KHz which record the ionograms at every 10 minute interval, while for the drift mode the system is operated at few fixed frequencies with high temporal resolution of ~1 minute between two successive ionograms (Figures S21 to S28)
