Description
NASA's Magnetospheric Multiscale 2 spacecraft provides Level-2 science data at a 30-millisecond burst resolution. The dataset includes spacecraft position, velocity, attitude, and magnetic ephemeris calculated using the Tsyganenko 1989 model for disturbed conditions. It also contains magnetic field measurements, footpoint coordinates, activity indices, and coordinate transformation quaternions.
Use Cases
Modeling disturbed magnetospheric magnetic field lines based on the Tsyganenko 1989 model parameters.
Analyzing spacecraft trajectory and orientation in multiple coordinate systems based on the provided rotational quaternions.
Correlating satellite observations with geomagnetic activity using the included Dst and Kp indices.
Studying particle loss cone dynamics based on the calculated northern and southern hemisphere loss cone angles.
Strengths
Data is collected at a high 30-millisecond time resolution in burst mode.
Includes magnetic field line tracing and footpoint calculations using a specified field model.
Provides coordinate transformations from GEI into 11 other coordinate systems.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment.
Data is stored in a BIN format, which may require specialized tools for access.
