ACE MAG SWEPAM: 4-Minute Merged Solar Wind and Magnetic Field Data

Merged 4-minute resolution magnetic field and plasma parameter data from the ACE spacecraft's MAG and SWEPAM instruments. The dataset is provided by NASA's National Space Science Data Center (NSSDC) and was last updated in March 2026. It likely contains time-series measurements of solar wind properties and interplanetary magnetic field conditions.

Use Cases

• Modeling solar wind propagation based on plasma parameter moments.
• Correlating interplanetary magnetic field variations with geomagnetic activity.
• Analyzing solar wind structure and shocks based on merged plasma and field data.

Strengths

• Data originates from NASA's ACE spacecraft, a primary source for space weather monitoring.
• Provides merged data from two key instruments (MAG and SWEPAM) at a 4-minute temporal resolution.

Limitations

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