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,…

Atmospheric Soil Organic Particles

Lead Institution

Purdue University

Principal Investigator

Alexander Laskin

Recent discovery of atmospheric soil organic particles (ASOP), emitted through previously unrecognized atmosphere-land-surface interactions, suggests that ASOP may have a widespread impact over a…

Characterization of sea spray aerosol under future ocean conditions with implications for cloud formation processes

Lead Institution

State University of New York at Stony Brook

Principal Investigator

Josephine Aller

Project type

Large-Scale EMSL Research

Oceans cover 71% of the Earth's surface, contain nearly half the global primary productivity, and are a major source of atmospheric Sea Spray Aerosol (SSA) representing one of the most uncertain…

Examining the drivers of mineral weathering in humid to semiarid landscapes

Lead Institution

University of California, Davis

Principal Investigator

Rebecca Lybrand

Project type

Large-Scale EMSL Research

Mycorrhizae, the symbiotic relationships between plant roots and fungi, are the primary suppliers of growth-limiting nutrients to plants and the main transporters of carbon from plants to soils…

Fundamental Studies of Ice Nucleation Using Environmental Scanning Electron Microscope (ESEM)

Lead Institution

Purdue University

Principal Investigator

Large-Scale EMSL Research

The proposed research is to demonstrate applicability of a novel experimental platform for systematic studies of ice nucleation efficiency of atmospheric particles with determination of…

Secondary Organic Aerosol Formation Mechanisms and Growth Dynamics

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Rahul Zaveri

Project type

Large-Scale EMSL Research

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…
