MARS EXPRESS ASPERA-3: Calibrated Electron Spectrometer Data for 2017-2018

Mars Express satellite data from the ASPERA-3 Electron Spectrometer (ELS) for the sixth mission extension. The calibrated data covers January 1, 2017, to December 31, 2018, and is provided in units of Differential Number Flux (cnts/(cm**2-sr-sec-eV)). The dataset originates from the National Aeronautics and Space Administration and was last updated on the platform in March 2026.

Use Cases

• Modeling the Martian plasma environment based on calibrated electron flux data.
• Analyzing temporal variations in electron populations around Mars based on the 2017-2018 time series.
• Studying atmospheric escape processes from Mars based on electron spectrometer measurements.
• Validating space weather models for Mars based on in-situ electron observations.

Strengths

• Data is calibrated, which suggests a processed, analysis-ready state.
• Covers a specific two-year time range (January 1, 2017 - December 31, 2018).
• Provided by the authoritative source, the National Aeronautics and Space Administration.

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.
