CLOUD Experiment: Sub-10 nm Atmospheric Particle Size-Distribution Data

Data from the CERN CLOUD10 (Fall 2015) and CLOUD12 (Fall 2017) campaigns, measuring sub-10 nm particle size-distributions. The dataset is associated with a 2022 publication and was measured with a DMA-train instrument. It was authored by Dominik Stolzenburg from the University of Helsinki.

Use Cases

• Modeling particle growth rates based on measured size-distribution data.
• Analyzing the impact of precursor gas concentrations on aerosol nucleation.
• Studying the temporal evolution of atmospheric particle concentrations from timestamped measurements.

Strengths

• Data is associated with a peer-reviewed publication in Environmental Science: Atmospheres.
• Measurements were conducted during controlled CERN CLOUD experiment campaigns.

Limitations

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