MARSIS: Mars Express Subsurface and Ionosphere Sounding Telemetry

MARSIS instrument telemetry from the Mars Express orbiter, edited for data corruption. The dataset includes both subsurface and ionosphere sounding observations, with computed geometric information for spatial and temporal location. It was produced by the National Aeronautics and Space Administration and last updated in March 2026.

Use Cases

• Modeling Martian subsurface geological structures based on radar sounding data.
• Analyzing ionospheric conditions and variability based on ionosphere sounding data.
• Correlating scientific observations with specific locations and times based on the computed geometric information.
• Validating instrument performance and data integrity by examining the editing for duplicated and corrupted packets.

Strengths

• Data has been edited for duplicated and corrupted packets, indicating a level of quality control.
• Includes both subsurface and ionosphere sounding data, providing a dual-purpose dataset.
• Contains computed geometric information for precise spatial and temporal location of observations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
