Optical Particle Counter measurements detail aerosol concentrations across specific particle diameters. Data was collected during the 2017 ARAON research expedition in the Arctic Ocean by the AMD_KOPRI organization. The dataset was last updated in September 2017.
Use Cases
- Analyze the relationship between particle diameter and concentration to model aerosol size distributions.
- Correlate aerosol concentration time-series data with other atmospheric measurements from the expedition.
- Study the spatial variability of aerosol properties across the Arctic Ocean sampling locations.
- Validate satellite-derived aerosol optical depth products using in-situ particle concentration measurements.
Strengths
- Data originates from a dedicated Arctic research expedition (ARAON, 2017).
- Focuses on a specific and climatically sensitive region, the Arctic Ocean.
- Provides measurements for multiple particle diameter channels.
Limitations
- Sample size and temporal coverage are limited to a single expedition year.
- Specific row count, column details, and data completeness metrics are unknown.
- Data is from 2017 and may not reflect current atmospheric conditions.
