Aerosol mixing state effects on optical properties

Calculations of the aerosol direct effect on climate rely on simulated aerosol fields. The model representation of aerosol mixing state potentially introduces large uncertainties into these calculations, since the simulated aerosol optical properties are sensitive to mixing state. This PhD project aims to systematically quantify the impact of aerosol mixing state on aerosol optical properties

Key Findings

  • Mixing state significantly affects aerosol absorption
  • Core-shell assumptions can lead to biases in optical property calculations
  • Particle-resolved modeling provides more accurate estimates
