PHOENIX Mars Lander Meteorological Pressure and Temperature Data

The PHX METEOROLOGICAL DATA product contains calibrated temperature and pressure data from the Phoenix Mars Lander. Temperature was collected at 250, 500, and 1000mm heights, and pressure at the Lander deck height, with data provided at 2-second resolution and 512-second averages. The dataset is produced by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Modeling Martian atmospheric dynamics based on high-resolution temperature and pressure time-series
• Analyzing vertical temperature gradients based on measurements at three distinct heights
• Studying pressure sensor heating effects using the provided corrected pressure values
• Conducting statistical analysis of atmospheric phenomena using the 512-second averaged data with distribution statistics

Strengths

• Data is provided at a high 2-second temporal resolution for detailed analysis
• Includes corrected pressure values to account for sensor heating effects
• Temperature measurements are taken at three distinct heights (250, 500, 1000mm) for vertical profile analysis

Limitations

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