MARS EXPRESS ASPERA-3: Ion Mass Analyzer Flux Data for 2021-2022

Mars Express ASPERA-3 Ion Mass Analyzer data provides differential number flux measurements of ions around Mars. The dataset covers the eighth mission extension from January 1, 2021, to December 31, 2022. Data are provided in units of m-2 s-1 sr-1 eV-1 by the National Aeronautics and Space Administration.

Use Cases

• Modeling the Martian atmospheric escape based on ion flux measurements.
• Analyzing temporal variations in the Martian plasma environment based on the two-year time range.
• Studying the interaction between the solar wind and the Martian atmosphere based on differential number flux data.

Strengths

• Covers a specific two-year time range from 2021 to 2022.
• Data are provided in a specific scientific unit (m-2 s-1 sr-1 eV-1).
• Originates from the National Aeronautics and Space Administration.

Limitations

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