AMD_KOPRI measured aerosol scattering coefficients at wavelengths of 450, 550, and 700nm using a nephelometer in the Antarctic ocean. Data collection occurred nearly continuously during the 2011-2012 period. The dataset was last updated in February 2012.
Use Cases
- Analyze temporal trends in scattering_coefficient_450nm to study seasonal aerosol variability.
- Compare scattering_coefficient_550nm with satellite-derived aerosol optical depth for validation.
- Model wavelength dependence using ratios between coefficients at 450nm, 550nm, and 700nm.
- Correlate nephelometer-measured scattering coefficients with local meteorological data to identify source processes.
Strengths
- Continuous measurements across the 2011-2012 time frame provide temporal resolution.
- Coefficients for three distinct wavelengths (450, 550, 700nm) enable spectral analysis.
Limitations
- Unknown sample size and geographic coverage beyond 'Antarctic ocean'.
- Data is over a decade old, limiting analysis of recent atmospheric changes.
