Aerosol Aging and Climate Change (Cowin's NOAA, PNNL Scope #47840)

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
James Cowin
Project type
Exploratory Research
Using easily field-deployable, time-resolved aerosol collectors (TRAC and TAQ) create sample archives that permit quantitative, single particle-size and elemental-composition analysis of mixed…

Understanding Reactive Nitrogen Recycling on Soil and Mineral Dust Surfaces

Lead Institution
Indiana University - Bloomington
Principal Investigator
Jonathan Raff
Project type
Large-Scale EMSL Research
A fundamental understanding of the factors controlling the lifetime and fate of reactive nitrogen oxides (NOy = NO, NO2, HNO2, N2O5, etc.) in the atmosphere is critical for accurately representing…

The Cloud Nucleating Properties of Aerosols at a Continental Site: CHAPS Study

Lead Institution
Shenyang Pharmaceutical University
Principal Investigator
Jian Wang
Project type
Large-Scale EMSL Research
The primary goal of The Cumulus Humilis Aerosol Processing Study (CHAPS) is to characterize and contrast freshly emitted aerosols above, within and below fields of cumulus humilis (or fair-weather…

Use of SEM/EDX Analysis to Study the Oxidation of Aerosol by Hydroxyl Radical

Lead Institution
University of California, Irvine
Principal Investigator
Barbara Finlayson-Pitts
Project type
Exploratory Research
Unique chemistry at the air-water interface between chloride ion in sea salt aerosol and the hydroxyl radical (OH) has been suggested to play a major role in the production of increased levels of…

Evaluation of Municipal Incinerator Contribution to Spokane PM

Lead Institution
Washington State University
Principal Investigator
Dennis Finn
Project type
Exploratory Research
The proposed project is designed to evaluate the what, if any contributions are made to particulate matter loading in Spokane, Washington due to emissions from the municipal waster incinerator west…

Characterization of Aerosol Organics by LC-MSn

Lead Institution
Desert Research Institute
Principal Investigator
Barbara Zielinska
Project type
Large-Scale EMSL Research
In summer, 2009, a comprehensive field study is planned to characterize the effect of organics on the water activity of atmospheric particles under sub- and supersaturated conditions at the Desert…

Chemical Imaging of Particles from TRACER field study

Lead Institution
Washington University in St. Louis
Principal Investigator
Rajan Chakrabarty
Project type
Large-Scale EMSL Research
This project will provide a physico-chemical description of individual atmospheric particles collected during the TRACER campaign, during which we will conduct systematic studies of composition and…
