Collection of data sources for the Arctic CLoud Observations Using airborne measurements d

22 research flights were conducted by two aircraft (Polar 5 and 6) northwest of Svalbard between 23 May and 26 June 2017. The data set, compiled by André Ehrlich of Leipzig University, unites measurements of meteorological parameters, turbulent and radiative energy fluxes, cloud and aerosol particles, and trace gases. The objective was to study Arctic boundary layer and mid-level clouds and their role in Arctic amplification.

Use Cases

• Modeling Arctic boundary layer cloud properties based on in-situ aircraft measurements.
• Analyzing radiative energy fluxes over the ocean-ice transition zone.
• Studying aerosol-cloud interactions in the Arctic based on particle characterization data.
• Validating remote sensing retrievals using co-located active and passive instrument data from Polar 5.

Strengths

• Data from 22 coordinated research flights provides multiple observational snapshots.
• Two aircraft with complementary instrumentation (remote sensing and in-situ) offer a multi-faceted view.
• Campaign focused on a specific, climatically important transition zone between open ocean and closed sea ice.

Limitations

• Row count and file formats are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
