Recent theoretical and laboratory studies have revealed that the timescales of secondary organic aerosol (SOA) partitioning and the associated aerosol size distribution growth dynamics depend on the…

Studies to Improve the Representation of Ice Nucleation in Models of the Arctic Climate

Lead Institution

University of British Columbia

Principal Investigator

Allan Bertram

Project type

Large-Scale EMSL Research

The Arctic region has been shown to be especially sensitive to climate change. Ice and mixed-phase clouds play an important role in climate in this region. Nevertheless, regional and global climate…

The Amazonian region has been documented to be a source of a wide range of aerosol particle types including biogenic secondary organic aerosol (SOA) and salts, primary biological aerosol particles,…

GOAmazon: Atmospheric Aerosol Phase, Composition, and Water Vapor Uptake

Lead Institution

Lawrence Berkeley National Laboratory

Principal Investigator

Mary Gilles

Project type

Large-Scale EMSL Research

Atmopsheric particle phase, viscosity, and mixing state are inherently intertwined with one another. How particles change and evolve, particularly as a function of relative humidity is crucial for…

Analysis of Mixing States and Morphology of Individual Particles for Improved Representation in Atmospheric Models

Lead Institution

Sonoma Technology

Principal Investigator

Ryan Moffet

Project type

Large-Scale EMSL Research

Atmospheric aerosols affect the climate directly by absorbing and scattering radiation and indirectly by impacting the properties and lifetimes of clouds. Aerosol processes, such as wet removal,…
