SOHO CELIAS Proton Monitor: 30-Second Solar Wind Energy per Charge Data

The Proton Monitor is a solar wind Energy per Charge analyzer of a new design, consisting of a three-box deflection system followed by a wedge-shaped MicroChannel Plate assembly. Data are derived from sets of 6 rates obtained every 30 seconds, with voltage steps spaced logarithmically from about 0.3 to 3 kV. The dataset is provided by the National Aeronautics and Space Administration.

Use Cases

• Analyzing solar wind energy per charge distribution based on voltage step measurements.
• Studying solar wind dynamics based on 30-second temporal resolution.
• Modeling plasma instrument performance based on the described geometry factor.
• Correlating solar wind parameters with other space weather data based on the energy per charge dynamic range.

Strengths

• Data is collected at a high temporal resolution of 30 seconds.
• The instrument's geometry factor is specified as about 1.0 x 10^-4 cm^2.
• The voltage steps cover a defined range from about 0.3 to 3 kV.

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.
