MARSIS Reduced Data Record: Subsurface Radar Sounding Data from Mars Express

MARS EXPRESS MARS MARSIS REDUCED DATA RECORD SUBSURFACE V2.0 contains subsurface sounding data from the Mars Express orbiter. The data have been uncompressed, corrected for Automated Gain Control, aligned to a reference altitude, and range processed to correct for ionospheric distortion of the transmitted signal. The dataset was last updated on 2026-03-13 and originates from the National Aeronautics and Space Administration.

Use Cases

• Map subsurface geological layers based on processed radar sounding data.
• Analyze Martian ice deposits and potential water resources based on subsurface radar reflections.
• Model ionospheric effects on radar signals for instrument calibration.
• Study Martian polar layered deposits and their stratigraphy based on subsurface data.

Strengths

• Data has been processed to correct for Automated Gain Control and ionospheric distortion.
• Dataset originates from the authoritative source, the National Aeronautics and Space Administration.
• Last updated on 2026-03-13, indicating recent maintenance.

Limitations

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