Ulysses URAP PFR: 10-Minute Average Electric Field Spectra

Averages of electric field intensities from the Ulysses URAP instrument's Plasma Frequency Receiver, measured in 10-minute intervals. The data contains frequency spectra from 0.57 to 35 kHz, measured on the X antenna in units of microvolt/Hz^0.5. The dataset is provided by the National Aeronautics and Space Administration via CDAWeb.

Use Cases

• Analyzing solar wind plasma wave activity based on electric field intensity averages.
• Studying frequency spectra dynamics in the heliosphere based on 16-channel measurements.
• Modeling plasma wave propagation based on data from the Ulysses spacecraft's URAP instrument.
• Investigating long-term trends in interplanetary electric fields based on 10-minute averaged data.

Strengths

• Data originates from the authoritative Ulysses URAP instrument operated by NASA.
• Provides averaged electric field intensities across 16 distinct frequency channels.
• Measurements are temporally resolved at 10-minute intervals.

Limitations

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