MARS EXPRESS ASPERA-3 IMA: Ion Flux Data for 2017-2019

Mars Express spacecraft data collected by the ASPERA-3 Ion Mass Analyzer from January 1, 2017 to January 1, 2019. The National Aeronautics and Space Administration provides measurements of differential number flux in units of m-2 s-1 sr-1 eV-1.

Use Cases

• Modeling Mars atmospheric loss rates based on ion flux measurements.
• Analyzing temporal variations in Martian ionospheric composition.
• Correlating solar activity with ion flux levels observed at Mars.
• Studying the spatial distribution of ions around Mars from spacecraft data.

Strengths

• Data covers a defined two-year period from 2017 to 2019.
• Measurements are provided in standardized scientific units (m-2 s-1 sr-1 eV-1).
• Data originates from a NASA spacecraft instrument.

Limitations

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