Helios 2: 40-Second Merged Magnetic Field and Plasma Data

Helios 2 satellite data combining magnetic field and plasma measurements at 40.5-second intervals. The dataset was created by the National Aeronautics and Space Administration (NASA) and was last updated on March 13, 2026.

Use Cases

• Analyze correlations between magnetic field strength and plasma parameters based on the merged data.
• Model solar wind propagation and turbulence based on high-cadence time-series measurements.
• Validate magnetohydrodynamic (MHD) simulations of the inner heliosphere based on in-situ satellite observations.

Strengths

• Data is merged from two instrument types (magnetic field and plasma), likely enabling correlated analysis.
• Last update recorded as 2026-03-13, suggesting potential maintenance or versioning.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
