Multi-source Storm-time Density Dataset (2000–2025)

1. Data background and generation method This dataset integrates multi-source observation data from 2000 to 2025, including in-situ observation data from China's "Tianmu-1" low orbit satellite constellation, atmospheric density results from international classic low orbit satellites such as CHAMP and GRACE; 2. Data files and naming conventions The data is stored in. mat format and archived independently according to magnetic storm events, which can be directly read by Matlab; The file name follows the rule of [satellite] _storm_ [year month day]. mat 3. Data column names and meanings Observation time (UTC) satellite geographic location (latitude/longitude, °) orbital altitude (km) thermosphere atmospheric density (kg/m ³) This dataset provides key support for studying the coupling mechanism between geomagnetic storms and thermosphere, improving the accuracy of low orbit satellite orbit forecasting, and evaluating space weather effects.
