CAMP2Ex: Aircraft Measurements of Clouds, Aerosols, and Trace Gases

NASA's CAMP2Ex field study collected in-situ and remote sensing data to investigate aerosol-cloud interactions and monsoon processes. The dataset includes cloud and precipitation retrievals from radar and radiometer, alongside in-situ trace gas measurements from the P-3B aircraft. The coordinated campaign involved 19 P-3B flights and 11 Learjet flights over the Philippines from August 20 to October 10, 2019.

Use Cases

• Analyzing aerosol effects on cloud microphysical properties based on coordinated aircraft measurements.
• Characterizing anthropogenic versus natural aerosol sources using trace gas tracers for airmass analysis.
• Validating satellite-based cloud and precipitation retrievals with detailed in-situ and remote sensing profiles.
• Studying meteorological influences on aerosol distribution and cloud interactions in a monsoon region.

Strengths

• Data collection is complete from a major NASA field campaign with a coordinated multi-aircraft sampling strategy.
• Combines multiple measurement types: remote sensing (radar, radiometer, lidar, polarimeter) and in-situ (aerosols, trace gases, meteorology, radiation).
• Campaign executed 30 total science flights (19 P-3B, 11 Learjet) over a focused 7-week period.

Limitations

• Column names and dataset size are unspecified across all sources, limiting detailed assessment of structure.
• Conflicting last-updated dates (2019-10-07 vs. 2026-03-13) suggest potential metadata inconsistency across platforms.
• License is ambiguously listed as 'other-license-specified' without explicit terms.
