King Sejong Station in Antarctica recorded cloud condensation nuclei number concentration data throughout 2017. The dataset was collected by the Korea Polar Research Institute (KOPRI) using a CCN-100 instrument from TSI, USA. Measurements were taken at a high frequency of 1 Hz.
Use Cases
- Analyze temporal trends in CCN number concentration to study seasonal aerosol variability in Antarctica.
- Correlate high-frequency 1Hz CCN measurements with concurrent meteorological data to understand nucleation events.
- Use the location-specific data from King Sejong Station as a baseline for polar atmospheric composition models.
- Investigate instrument-derived CCN concentration for calibration and validation of satellite-based aerosol products.
Strengths
- Data covers a full calendar year of 2017 for continuous temporal analysis.
- High temporal resolution of 1Hz provides detailed event-scale data.
Limitations
- Dataset is limited to a single year, preventing long-term trend analysis.
- Geographic scope is restricted to one Antarctic station, limiting spatial representativeness.
- Unknown sample size and data completeness prevent statistical certainty.
