Possible warming effect of fine particulate matter in the atmosphere

S. Chen, S. Chang, et al.

Discover how sulfate-containing aerosols, traditionally seen as cooling agents, may contribute to warming the Earth under specific conditions. This intriguing study by Shau-Liang Chen, Sih-Wei Chang, Yen-Jen Chen, and Hsuen-Li Chen sheds new light on the complex interactions between particulate matter and climate change.

Abstract
Particulate matter (PM) from human activities cools the Earth by scattering solar radiation. However, coarser dust particles exert a warming effect. This study investigates the radiative effects of sulfate-containing aerosols using Mie scattering and 3D finite-difference time-domain simulations. The findings reveal that fine, non-light-absorbing inorganic aerosols like sulfate can also have a warming effect due to their absorption and re-emission of thermal radiation under resonance conditions at long wavelengths. These effects should be considered when assessing aerosol contributions to climate change.
