ACE SWEPAM: Solar Wind Plasma Data Interpolated to 60-Second Resolution

NASA's Advanced Composition Explorer (ACE) satellite provides processed solar wind plasma data. The measurements have been linearly interpolated to a 60-second resolution at the spacecraft's position, originally constructed for superposed epoch and cross-correlation studies. The dataset was last updated on March 13, 2026.

Use Cases

• Conduct superposed epoch analysis based on the processed solar wind time series.
• Perform cross-correlation studies between solar wind parameters based on the 60-second resolution data.
• Model space weather effects using the interpolated plasma measurements from the ACE spacecraft.
• Analyze temporal patterns in solar wind for research linked to NSF GEM and Space Weather grants.

Strengths

• Data is processed and linearly interpolated to a consistent 60-second resolution.
• Originates from NASA's ACE satellite, an authoritative source for solar wind measurements.
• Constructed for specific NSF-funded research studies (GEM Grant ATM 02-1798 and Space Weather Grant ATM 02-08501).

Limitations

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