ACE: Solar Wind Magnetic Field Measurements at 60-Second Resolution

Linearly interpolated tri-axial fluxgate magnetometer data from the Advanced Composition Explorer (ACE) spacecraft, processed to a 60-second resolution in GSM coordinates. The dataset was constructed by Dr. J.M. Weygand for Prof. R.L. McPherron under NSF grants ATM 02-1798 and ATM 02-08501. It has been used for superposed epoch and cross-correlation studies on solar wind phenomena.

Use Cases

• Conducting superposed epoch analysis based on the processed solar wind data mentioned in the description
• Performing cross-correlation studies between solar wind parameters and geomagnetic activity
• Modeling solar wind-magnetosphere coupling based on high-time-resolution magnetic field vectors
• Analyzing temporal patterns in interplanetary magnetic field data for space weather forecasting

Strengths

• Data is processed and linearly interpolated to a consistent 60-second time resolution
• Originates from the ACE spacecraft, a key solar wind monitor operated by NASA
• Associated with specific NSF-funded research projects (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
