The Water Content of Organic Aerosol Predicts Its Viscosity

Simulations show a strong correlation between the water content and the viscosity of organic aerosol over the Amazon rainforest.

Aging Alters Mixing Behavior of Organic Aerosol

Experiments show fresh organic aerosol readily mix and mingle but remain separated as they age; results inform model assumptions about particle growth.

Climate Model Approximations of Aerosol Sizes Lead to Inaccurate Cloud Droplet Nucleation

Researchers developed a framework for representing aerosol particles in climate models.
