ST Radar 205 MHz -Ionospheric Data
This Ionospheric data is retrieved from the Stratosphere-Troposphere (ST) Radar operating at 205 MHz in the VHF band, and is the first wind profiler radar in the ~200 MHz frequency range, which constitutes 619 three-element Yagi–Uda antennae. It has a power aperture product of 1.6x10^8 Wm^2. System design, technical details and scientific applications of the 205 MHz radar are already reported [Samson et al., 2016; Mohanakumar et al., 2017; 2018]. The main beam can be positioned at any angle within of ±30° of the zenith and at all azimuth with 1° resolution. The data was archived with radar beam set to 8° towards north to satisfy the condition of perpendicularity, consistent with the estimate from IGRF12. The experiment configuration and parameters used are given in Table-1. The range resolution was 45 metres.
