LANL1990 MPA: Magnetospheric Plasma Analyzer Data at 87-Second Resolution

LANL 1990-095 satellite data captures plasma conditions in geosynchronous orbit. The Magnetospheric Plasma Analyzer (MPA) recorded density, velocity, and temperature for ions and electrons at approximately 87-second intervals. NASA provides this data in multiple coordinate systems, including spacecraft and magnetic coordinates.

Use Cases

• Modeling magnetospheric plasma dynamics based on ion and electron density and temperature measurements.
• Analyzing space weather events based on time-series plasma parameters at geosynchronous orbit.
• Correlating satellite position data with plasma observations based on provided coordinate systems.
• Studying energetic particle populations based on separate low and high energy ion and electron data.

Strengths

• Data includes multiple coordinate systems (GEI, spacecraft, polar geographic, polar magnetic).
• Parameters cover both low and high energy ions and electrons.
• Time resolution is specified as approximately 87 seconds.

Limitations

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