Juno MWR: Jupiter Water Abundance by Pressure Level

JUNO JUPITER MWR WATER DISTRIBUTION V1.0 is a nonaccumulating dataset from NASA's Juno mission. It contains water abundance and its 1-sigma uncertainty as a function of pressure level in bars, derived from high-rate perijove data. The dataset was last updated on March 13, —2026.

Use Cases

• Modeling Jupiter's atmospheric water distribution based on pressure-dependent abundance data.
• Analyzing uncertainty in remote sensing measurements based on the provided 1-sigma values.
• Comparing atmospheric composition across different planetary bodies based on water abundance profiles.
• Validating physical models of gas giant atmospheres based on empirical water abundance data.

Strengths

• Data originates from NASA's Juno spacecraft, a primary scientific mission.
• Includes quantified uncertainty (1-sigma) for the water abundance measurements.
• Dataset is versioned (V1.0), suggesting a managed release process.

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.
