Abstract & Keywords
Abstract: The Very High Frequency (VHF) coherent scatter radar of Meridian Project is located in Fuke, Hainan Island of China (109.1\(°\)E, 19.5\(°\)N), and belongs to National Space Science Center, Chinese Academy of Sciences. The radar beams are set to be perpendicular to the magnetic field lines in ionospheric E- and F-layers in order to obtain the backscattered echoes from ionospheric field-aligned irregularities. The VHF coherent scatter radar continuously detected the plasma irregularities in E- and F-region from 2014 to 2019, and the real-time echo intensity calculated from I/Q signals is uploaded to Meridian Project Data Center. With this dataset, we can obtain the dependences of ionospheric irregularities occurrence on solar activity, seasons, and local time in the low-latitude region (Hainan), as well as the day-to-day variations and response characteristics during geomagnetic storms of irregularities. The dataset will provide support for research, projects as well as space weather forecast in the field of ionospheric physics.

Dataset compositionThe dataset comprises echo intensity data of VHF coherent scatter radar at Fuke, Hainan, totaling 23,313 data files, with one data file produced every 2 hours. A data file consists of a file header and data segments. The file header consists of station code, equipment code, observation start time, observation area, observation mode, scanning wave number, beam scanning period, pulse repetition frequency, coherent accumulation number and incoherent accumulation number. Data segments consist of several data blocks arranged based on the scanning timing sequence, recording scan duration, beam number, echo range and echo intensity (dB).
