APPRAISE Clouds: In-Situ Aerosol and Cloud Measurements from 20 Research Flights

20 research flights collected ground-based and airborne in-situ aerosol measurements for the APPRAISE-CLOUDS project. The data were gathered from the Chilbolton Atmospheric Observatory in Hampshire and using the FAAM BAE-146 aircraft operating from Cranfield, Exeter, and Oberpffafenhofen, Germany. The Centre for Environmental Data Analysis provides this dataset under the OGL-UK-3.0 license.

Use Cases

• Modeling aerosol-cloud interactions based on in-situ measurements of cloud droplets and ice particles.
• Analyzing aerosol chemistry and size distributions based on data from instruments like the AMS, PCASP, and SMPS.
• Characterizing soot aerosol concentrations based on measurements from the SP2 and PSAP instruments.
• Studying trace gas concentrations (NOx, O3, SO2) in the vicinity of clouds based on data from whole air samplers and trace gas analysers.

Strengths

• Includes data from 20 specific research flights detailed in the description.
• Covers 110 flight hours allocated to the project.
• Measurements were taken using a range of specialized instruments for cloud, aerosol, and trace gas analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
