Wind 3DP: Corrected Solar Wind Electron Moments at 100-Second Resolution

NASA's Wind spacecraft provides corrected electron plasma parameters, accounting for spacecraft potential and instrumental effects. The dataset is derived from EESA-L and EESA-H instrument measurements, with methodology detailed in peer-reviewed publications from 1995, 2017, and 2014. Data is maintained by the National Aeronautics and Space Administration and was last updated on March 13, 2026.

Use Cases

• Modeling solar wind dynamics based on corrected electron density and temperature moments.
• Studying spacecraft-plasma interactions based on potential correction methods described in the literature.
• Analyzing time-series trends in solar wind electron properties at 1 AU.
• Validating plasma simulation outputs against in-situ satellite measurements.

Strengths

• Data is corrected for spacecraft potential and instrumental effects, as described in multiple peer-reviewed journal articles.
• Produced and maintained by the National Aeronautics and Space Administration, a leading space agency.
• Last updated on March 13, 2026, indicating recent maintenance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
