Parker Solar Probe (PSP): Hourly Merged Magnetic Field and Solar Wind Plasma Data

NASA's Parker Solar Probe (PSP) data provides hourly measurements of the solar environment. The dataset merges magnetic field readings from the FIELDS instrument with plasma parameters like proton density, velocity, and temperature from the SWEAP instrument. It was created by NASA's Space Physics Data Facility and last updated in March 2026.

Use Cases

• Correlating solar wind proton velocity with magnetic field vector changes based on the merged plasma and magnetometer data.
• Modeling heliospheric conditions using the derived proton number density and thermal speed parameters.
• Analyzing time-series trends in solar wind properties based on the hourly data resolution.

Strengths

• Data is derived from high-resolution source products (PSP_FLD_L2_MAG_RTN_1MIN and PSP_SWP_SPC_L3I).
• Includes multiple validated physical parameters: magnetic field vectors, proton density, velocity, and temperature.
• Last updated on 2026 03 13, indicating recent maintenance.

Limitations

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