Aerosol Particle Formation Measurements from Finland Using Lidar and Airborne Data

Doppler lidar and ion spectrometer data from Hyytiälä, Finland, collected on May 1-2, 2017. Airborne measurement data from southern Finland was gathered using an instrumented Cessna 172 during several campaigns between 2011 and 2018. The dataset, compiled by Janne Lampilahti of the University of Helsinki, also includes new particle formation event classifications.

Use Cases

• Classifying new particle formation events based on the provided event classifications.
• Analyzing atmospheric layer dynamics based on Doppler lidar measurements.
• Studying ion concentration and its role in particle formation using ion spectrometer data.
• Correlating ground-based and airborne atmospheric measurements from different campaigns.

Strengths

• Includes data from multiple instrument types: Doppler lidar, ion spectrometer, and airborne sensors.
• Covers a multi-year time span for airborne data, from 2011 to 2018.
• Provides event classifications for new particle formation, adding analytical value.

Limitations

• Row count and dataset size 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.
