ACE MAG SWEPAM: Merged Solar Wind Magnetic Field and Plasma Data

ACE MAG and SWEPAM L2 64-s merged magnetic field and plasma parameter moments data at ASC. The dataset is provided by the National Aeronautics and Space Administration (NASA) and was last updated on March 13, 2026.

Use Cases

• Modeling solar wind propagation based on merged magnetic field and plasma parameters.
• Analyzing correlations between magnetic field strength and plasma moments for space weather forecasting.
• Studying solar wind structure and variability using 64-second resolution time-series data.

Strengths

• Data is sourced from NASA's Advanced Composition Explorer (ACE) satellite, a primary source for solar wind observations.
• Provides merged data from two instruments (MAG and SWEPAM), offering a coordinated view of solar wind conditions.
• Last updated date of 2026-03-13 suggests ongoing maintenance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total dataset size are unknown, which may limit suitability assessment.
• Data is provided in BIN format, which may require specialized tools for access and analysis.
