PSP FIELDS DFB: Parker Solar Probe Search Coil Magnetometer Spectral Data

Spectral data from the Digital Fields Board (DFB) search coil magnetometer on the Parker Solar Probe spacecraft. The dataset contains calibrated power spectral densities for magnetic fields and voltages, expressed in sensor coordinates, with a data cadence of 0.873813 seconds. It is a Level 2 product from NASA's FIELDS experiment, last updated in March 2026.

Use Cases

• Analyzing solar wind turbulence based on magnetic field power spectral densities.
• Studying plasma wave modes and frequencies from calibrated AC spectra.
• Investigating high-frequency signal trends and noise characteristics in the DFB frequency range.
• Comparing magnetic field components in different sensor coordinate systems ([d,e,f] vs [u,v,w]).

Strengths

• Data is calibrated for six specific factors including Hanning window, in-band gain, and filter responses.
• Spectral data is provided in pseudo-logarithmically spaced frequency bins with reported central frequencies.
• Produced by NASA, an authoritative source for space mission data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Voltage sensor quantities lack corrections for plasma sheath impedance and antenna effective length, which are deferred to Level 3 products.
