Review reveals how aerosol and boundary layer interactions suppress pollutant dispersion, highlighting positive feedback loops during severe air pollution.

Key Points

To review advances in understanding how diurnal planetary boundary layer evolution interacts with atmospheric aerosols through complex feedback mechanisms to impact air quality.
Synthesized observational and theoretical literature on aerosol measurement techniques and vertical planetary boundary layer processes.
Assessed thermodynamic feedback mechanisms driven by aerosol scattering and absorption of solar radiation.
Aerosol scattering and absorption reduce solar radiation reaching the ground, lowering surface sensible heat fluxes and weakening planetary boundary layer growth.
Aerosol-induced temperature inversions increase atmospheric stability, suppressing vertical dispersion and generating a positive feedback loop that intensifies surface pollution concentrations.
