Earth System Model Offers New View of Aerosol Treatments
Aerosol treatments in E3SM affect clouds, heat reflected to space, and Earth’s snow-or-ice-covered surface.
Aerosols Notably Contribute to the Predictability of Hail and Precipitation
Large ensemble simulations show that aerosols can significantly modify the predictability of hail and precipitation in hailstorms.
Exploring Aerosol Sources in the Southern Great Plains
Field campaign data shows that biologically-derived emissions largely control the formation of organic aerosol in the Southern Great Plains.
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.
Eastern North Atlantic Measurements Characterize Aerosol Particles and Their Sources
Researchers used instruments in an airborne lab to characterize aerosol particles and their sources over the remote Eastern North Atlantic.
