An Ionospheric Storm Scale Index Based on TEC: Comparative Analysis for China Region
Space Weather, Volume 24, Issue 8, August 2026.Abstract Defining a standardized ionospheric storm scale is challenging given the ionosphere's inherent complexity and susceptibility to multiple driving factors. In this study, a novel ionospheric storm scale (ISS) index is developed based on statistical analysis of total electron content (TEC) data from 257 ground‐based GNSS stations across China ...
