MARS EXPRESS ASPERA-3: Neutral Particle Imager Data from 2013-2014

NASA's Mars Express ASPERA-3 Neutral Particle Imager (NPI) data set contains particle count rates for the fourth mission extension from January 1, 2013 to December 31, 2014. The data are provided in units of counts per second. The dataset was last updated on March 13, 2026.

Use Cases

• Modeling Mars's neutral particle environment based on count rate data.
• Analyzing temporal trends in particle flux over the 2013-2014 period.
• Correlating neutral particle measurements with other Mars Express instrument data.
• Studying atmospheric escape processes from Mars.

Strengths

• Data covers a defined two-year time range from 2013 to 2014.
• Provided by the authoritative source NASA.
• Dataset was updated on March 13, 2026.

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.
