PHOENIX MARS ASE: Atmospheric Density, Pressure, and Temperature Profiles

Reduced Data Records (RDRs) from the Phoenix Mars Atmospheric Structure Experiment (ASE), produced by NASA. The dataset contains derived vertical profiles of atmospheric density, pressure, and temperature on Mars. The data was last updated on 2026-03-13.

Use Cases

• Modeling Martian atmospheric structure based on vertical density, pressure, and temperature profiles.
• Validating planetary climate simulations using in-situ derived atmospheric data.
• Analyzing atmospheric entry and descent conditions for Mars missions based on profile data.

Strengths

• Data originates from NASA's Phoenix Mars mission, a credible source for planetary science.
• Includes derived vertical profiles of key atmospheric variables: density, pressure, and temperature.
• Last updated on 2026-03-13, indicating recent metadata maintenance.

Limitations

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