ARCSIX: Arctic Cloud Microphysics from Aircraft Probes

ARCSIX_Cloud_AircraftInSitu_Learjet_Data contains in-situ cloud microphysics measurements from the SPEC-Learjet aircraft during the NASA ARCSIX campaign. The data feature measurements from probes including the 2D-Gray Particle Probe, 2D-Stereo Particle Probe, Fast Cloud Droplet Probe, High Volume Precipitation Spectrometer, and Nevzorov Water Vapor Probe. The campaign aimed to quantify contributions to the Arctic summer surface radiation budget and sea ice melt during the early melt season.

Use Cases

• Validating remote sensing algorithms for Arctic clouds based on in-situ particle size and shape distributions.
• Improving model parameterizations of cloud microphysics using detailed probe measurements.
• Analyzing the impact of specific cloud types on the surface radiation budget during the Arctic melt season.
• Studying aerosol-cloud interactions in the Arctic using coordinated in-situ and remote sensing datasets.

Strengths

• Data collection is explicitly stated as complete, indicating a finalized dataset.
• Features measurements from multiple specialized cloud physics probes (2D-Gray, 2DS, FCDP, HVPS, Nevzorov).
• Part of a coordinated NASA field campaign (ARCSIX) with multiple aircraft platforms, providing context.

Limitations

• Key metadata such as column names, row count, and file size are unknown across all sources.
• Conflicting last updated timestamps exist between sources (2024-08-17 and 2026-03-13).
• The provided descriptions are identical across platforms, suggesting limited unique metadata per listing.
