Data Of Sudden Ionospheric Disturbance Caused by Solar Flare Using The 3D Tomography GNSS-TEC Method
Description
This dataset contains the three-dimensional (3D) tomographic reconstruction of ionospheric electron density variations associated with the X1.1 solar flare event on 8 November 2013. The reconstruction was generated using GNSS-TEC observations collected from regional GNSS networks covering Indonesia, Australia, Taiwan, Japan, and New Zealand. The dataset consists of voxel-based 3D electron density anomaly matrices spanning altitudes from 50 km to 650 km with temporal coverage before, during, and after the solar flare event. Each voxel stores the reconstructed electron density perturbation derived from GNSS tomography. The dataset is provided to support visualization, validation, and comparative studies using independent ionospheric observations such as ionosondes, radio occultation measurements, and space weather monitoring systems. The reconstructed matrices capture the evolution of the Sudden Ionospheric Disturbance (SID) triggered by enhanced solar X-ray and EUV radiation, showing the strongest positive electron density anomalies between approximately 50–350 km altitude and their subsequent recovery. Associated metadata include observation time (UT), geographic coordinates, altitude levels, and voxel dimensions used in the tomographic inversion. These data are made publicly available to facilitate reproducibility of the published results and to encourage future investigations of ionospheric responses to solar flare events using complementary observational techniques.
