Magnetic field data in the ULF, ELF, and VLF frequency ranges is collected by the Search-Coil Magnetometer onboard China's Zhangheng-1 (CSES) satellite. The dataset captures time-varying signals related to space weather and seismic activity. It is archived by the National Remote Sensing Center of China (NRSCC) on the ChinaGEOSS platform.
Use Cases
- Detecting seismic precursors by analyzing anomalies in ULF magnetic field time-series.
- Studying ionospheric perturbations by correlating ELF/VLF signal variations with solar activity indices.
- Modeling space weather impacts by tracking the temporal evolution of magnetic field strength across different frequency bands.
- Classifying natural electromagnetic wave phenomena (e.g., whistlers, chorus) from the SCM instrument's spectral data.
Strengths
- Data originates from a dedicated satellite mission (Zhangheng-1/CSES) designed for seismo-electromagnetic observation.
- Covers three scientifically critical frequency bands: Ultra-Low Frequency (ULF), Extremely Low Frequency (ELF), and Very Low Frequency (VLF).
Limitations
- Specific data volume (rows), temporal coverage, and spatial resolution are unknown from the description.
- Data quality metrics, calibration details, and potential instrument noise characteristics are not provided.
