Development of data analysis and visualization software - SpectraMiner

Lead Institution
State University of New York at Stony Brook
Principal Investigator
Peter Imrich
Project type
Exploratory Research
Single Mass Spectrometers (SPMS) are capable of producing huge amounts of data in a short time, making data mining a daunting task. Analysis of SPMS data is particularly difficult because of their…

Fuel-Neutral Studies of Particulate Matter Transportation Emissions

Lead Institution
University of Wisconsin, Madison
Principal Investigator
David Foster
Project type
Exploratory Research
Customers and governments are demanding greater fuel efficiency in light duty engine applications. Since the majority of light duty engines in North America are fueled by gasoline, gasoline engine…

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Alla Zelenyuk-Imre
Project type
Exploratory Research
This research is focused on the development and application of unique tools and methods to study the fundamental properties and processes that govern the chemistry and microphysics of particles at…

The Formation and Structure of Tropical Organic/Water Aerosols

Lead Institution
University of Colorado at Boulder
Principal Investigator
Gayfree Ellison
Project type
Large-Scale EMSL Research
Atmospheric aerosols are widely recognized as key elements in many environmental issues ranging from global climate change and visibility to adverse effects on peoples health. Aerosols affect climate…

Chemical Imaging Analysis of Environmental Particles

Lead Institution
Purdue University
Principal Investigator
Alexander Laskin
Project type
Large-Scale EMSL Research
This project focuses on laboratory studies that investigate the relationship between particle morphology, composition, formation, reactivity, and evaporation by developing novel methods for chemical…

Secondary Organic Aerosol Formation from Nitrate Photochemistry

Lead Institution
University of California, Irvine
Principal Investigator
Barbara Finlayson-Pitts
Project type
Large-Scale EMSL Research
Secondary organic aerosols (SOA) in the troposphere are a major component of particulate matter and hence of interest with respect to health effects, visibility and radiative forcing. However, their…

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…

Chemistry and Microphysics of Small Particles

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Alla Zelenyuk-Imre
Project type
Large-Scale EMSL Research
This proposal is a continuation of research under EMSL User Proposal #17498. Atmospheric aerosol particles impact the global climate by scattering solar radiation to space and in their role as cloud…

Hygroscopic Properties of Aerosol Organics

Lead Institution
Desert Research Institute
Principal Investigator
Douglas Lowenthal
Project type
Large-Scale EMSL Research
While organics constitute a large fraction of ambient aerosol mass, their role and effect on particle hygroscopic growth and cloud nucleation remains unclear. Organics are most often present in…
