MEX: MARSIS Electron Density and Magnetic Field Data from Mars Orbit

Data from orbit 1850 to 2539 during the Mars Express nominal mission, tabulating local electron densities and magnetic field strengths derived from MARSIS radar ionograms. The dataset includes both measured quantities and derived results, along with a data quality flag for reliability assessment. It was created by the National Aeronautics and Space Administration (NASA).

Use Cases

• Modeling the Martian ionosphere based on electron plasma density measurements.
• Analyzing local magnetic field variations near Mars based on derived field strength data.
• Correlating radar sounding observations with solar activity based on the time-series nature of the orbital data.
• Assessing data reliability for scientific studies based on the included quality flag.

Strengths

• Includes both raw measurements and derived physical quantities (electron density, magnetic field strength).
• Covers a defined mission period from orbit 1850 to orbit 2539.
• Contains a data quality flag for reliability assessment.

Limitations

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