CRRES Aerospace Agency Tapes: Magnetospheric Particle and Field Data

Aerospace Corporation compiled raw telemetry data from eight scientific instruments on the CRRES satellite, including particle spectrometers and a photometer. The data covers specific orbits from the mission, with spacecraft ephemeris, attitude, and magnetic field information provided in separate files. NASA is the organization responsible for this dataset, which was last updated in March 2026.

Use Cases

• Modeling magnetospheric ion composition based on MICS, HIT, and LOMICS sensor data.
• Analyzing relativistic proton fluxes based on Relativistic Proton Detector (RPD) measurements.
• Correlating electron and proton spectra with spacecraft position using EPAS and MEA data and ephemeris files.
• Studying chemical release events based on photometer data mentioned in the description.
• Investigating magnetic field variations using computed vector components in sensor coordinates.

Strengths

• Data originates from eight distinct scientific instruments, providing multi-instrument measurements.
• Includes auxiliary data types: spacecraft ephemeris, attitude, and magnetic field vectors.
• Covers a defined mission segment from Orbit 6 to Orbit 1067, with specific on/off intervals noted.

Limitations

• Data is provided at raw telemetry level in complex binary form, requiring specialized processing.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
