CAMP2Ex: Aircraft and Satellite Observations of Clouds, Aerosols, and Radiation

From August 20 to October 10, 2019, this dataset contains measurements from the NASA CAMP2Ex field study in the vicinity of the Philippines. It includes in-situ and remotely sensed data on aerosol properties, cloud microphysics, radiation, and meteorology, collected from a NASA P-3B aircraft and a SPEC Learjet 35A. The data support research on aerosol-cloud interactions, radiative effects, and monsoon meteorology.

Use Cases

• Analyzing aerosol effects on cloud droplet concentration and size based on in-situ cloud microphysics measurements.
• Investigating radiative feedbacks using in-situ radiation flux measurements from the P-3 aircraft.
• Characterizing aerosol vertical profiles and types using remote sensing lidar and polarimeter data.
• Studying meteorological influences on aerosol distribution using in-situ temperature, humidity, and wind measurements.
• Validating satellite retrievals and model simulations of cloud and precipitation processes using coordinated aircraft data.

Strengths

• Data collection is explicitly stated as complete, providing a finalized observational record.
• Coordinated multi-platform strategy with 19 P-3B and 11 Learjet science flights enhances data context.
• Cross-platform presence on multiple data portals indicates established curation and importance.

Limitations

• Critical metadata is missing: no row counts, file sizes, or specific column names are provided.
• License is ambiguously listed as 'other-license-specified' without details on reuse terms.
• Update timestamps on datagov are in the future (2026), indicating potential metadata errors.
