Description
Helios 1 E1 (Rosenbauer) Hourly Plasma Data provides averaged solar wind measurements from the Helios 1 spacecraft. The dataset includes parameters such as proton bulk speed, temperature, number density, flow angles, and spacecraft position relative to the sun. It is provided by the National Aeronautics and Space Administration and was last updated in March 2026.
Use Cases
Modeling solar wind propagation based on proton bulk speed and density.
Analyzing solar wind parameter variability based on standard deviations of plasma measurements.
Correlating plasma conditions with spacecraft position based on sun-Helios distance and Carrington longitude.
Studying solar wind flow direction based on ecliptic elevation and azimuth angles.
Strengths
Data originates from a NASA spacecraft mission, providing authoritative measurements.
Includes derived statistical measures such as standard deviations for plasma parameters.
Contains positional context like sun-Helios distance and Carrington longitude.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment.
Data is stored in a BIN format, which may require specialized tools for access.
