Table 1_Kelvin–Helmholtz vortices in the magnetopause boundary layer associated with auror

A single event on 27 September 2016 observed by the MMS and DMSP satellites. The dataset reports on a Kelvin–Helmholtz vortex event at the magnetopause boundary layer, associated with auroral beads in the ionosphere. It was authored by YunTian Hou and published on figshare under a CC-BY-4.0 license.

Use Cases

• Study the relationship between magnetopause Kelvin–Helmholtz vortices and discrete auroral beads based on the described conjunction observations.
• Analyze field-aligned currents connecting the magnetospheric boundary layer to the ionosphere based on the MMS data mentioned.
• Investigate the scale ratio between large-scale vortices and small-scale precipitation regions based on the reported ~1,000 km and ~30 km scales.

Strengths

• Provides detailed multi-instrument observations from MMS and DMSP satellites for a specific event.
• Reports specific spatial scales: a Kelvin–Helmholtz vortex of ~1,000 km and an auroral electron precipitation region of ~30 km.
• Published under a permissive CC-BY-4.0 license.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
