MGS Sampler: Magnetometer and Electron Reflectometer Data Plots

NASA's Mars Global Surveyor spacecraft acquired electron flux and magnetic field observations during assessment orbits. The data consists of GIF plots showing electron fluxes at 10, 50, 130, 300, and 1000 eV, magnetic field amplitude, spacecraft altitude, and a color spectrogram. Numerical data will be released later after validation and calibration.

Use Cases

• Visualizing electron flux energy distributions based on the 10, 50, 130, 300, and 1000 eV energy levels mentioned in the description
• Analyzing magnetic field amplitude and variability around Mars based on the magnetic field observations
• Correlating spacecraft altitude with electron flux and magnetic field measurements based on the altitude data included in the plots

Strengths

• Data originates from NASA's Mars Global Surveyor mission, a credible source
• Plots include electron flux measurements at five specific energy levels: 10, 50, 130, 300, and 1000 eV
• Plots combine multiple derived observations: electron fluxes, magnetic field amplitude and rms, and spacecraft altitude

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Column-level documentation is absent; field semantics must be inferred after download
• The numerical data is not yet available, only preliminary plot images
