MARS EXPRESS ASPERA-3: Calibrated Electron Spectrometer Data for Mars, 2007-2009

NASA's MARS EXPRESS ASPERA-3 CAL RDR ELECTRON SPECTROMTR EXT2 V1.0 dataset contains calibrated electron spectrometer data from the Mars Express orbiter. The data covers the second mission extension from October 1, 2007, to May 31, 2009, and is provided in units of Differential Number Flux (cnts/(cm**2-sr-sec-eV)).

Use Cases

• Modeling Mars's plasma environment based on calibrated electron flux measurements.
• Analyzing temporal trends in electron populations around Mars based on the specified 2007-2009 time range.
• Studying atmospheric escape processes on Mars based on electron spectrometer data.
• Validating space weather models for Mars based on in-situ satellite observations.

Strengths

• Data is calibrated, which suggests a processed, analysis-ready state.
• Covers a defined 20-month time range from October 2007 to May 2009.
• Provided by the authoritative source NASA.

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.
