Single Particle Soot Photometer (SP2) data from the Dome Concordia station in Antarctica, measuring the optical size distribution of particles and the soot-core size distribution of soot-containing particles. The dataset was collected by the SCIOPS organization over a 30-day period during the Antarctic summers of 2018 and 2019. Measurements were taken at the high-altitude ATMOS clean air facility.
Use Cases
- Analyze the temporal evolution of particle optical size distribution over the 30-day measurement period.
- Characterize the soot-core size distribution to understand black carbon sources and aging processes in the Antarctic atmosphere.
- Correlate optical size and soot-core size features to infer particle mixing state and composition.
- Use the single-particle resolution data to validate or parameterize aerosol microphysics in climate models.
Strengths
- Single-particle resolution for detailed microphysical analysis.
- Data collected at a high-altitude (3233 m) clean air facility in Antarctica, minimizing local contamination.
- Covers a continuous 30-day period during the Antarctic summer, capturing seasonal conditions.
Limitations
- Limited temporal coverage to one summer season, lacking year-round or multi-year data.
- Geographic scope is restricted to a single station in East Antarctica.
- Unknown sample size (row count) and completeness of the recorded particle events.
