Lead Institution: University of Michigan
Principal Investigator: Kerri Pratt
The proposed project will address critical gaps in our understanding of the Arctic aerosol sources, chemical composition, and ice nucleation properties through chemical imaging and ice nucleation particle analysis of samples collected during three...
Lead Institution: Purdue University
Principal Investigator: Alexander Laskin
The intent of this collaborative research is to investigate photo-catalytic effects of atmospheric aging on the chemical composition and the microphysical properties of secondary organic aerosol (SOA) internally mixed with Fe(III)-rich mineral dust...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Fan Mei
We propose a combined experimental and modeling study to characterize the vertical profile of atmospheric aerosol collected via a tethered balloon system using multi-modal micro-spectroscopy techniques, advanced mass spectrometry platforms, and high...
Lead Institution: E.A. Fischione Instruments, Inc.
Principal Investigator: Cecile Bonifacio
The proposed work will aid in the development of a protocol that enables the preparation, handling, and transfer of samples under controlled environmental conditions for correlative analyses with focused ion beam (FIB), scanning electron microscopy...
Lead Institution: Environmental Molecular Sciences Laboratory
Principal Investigator: Swarup China
The radiative forcing of the ambient aerosol is strongly influenced by the vertical distribution of aerosols and their chemical composition, and not well constrained in climate models. Both satellite observation and ground-based measurements are not...
Lead Institution: University of Michigan
Principal Investigator: Kerri Pratt
Single-particle microscopy will be used to characterize the chemical composition of individual Arctic atmospheric particles collected during two Department of Energy Atmospheric Radiation Measurement (DOE ARM) field campaigns as part of PI Pratt...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Fan Mei
The vertical distribution of aerosol strongly influences the radiative forcing of the aerosols. However, observational data is limited. Both satellite observation and ground-based measurements are not able to provide well-resolved vertical profiles...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Sandra Taylor
The objective of this work is to elucidate atomic- to nano-scale mechanisms driving the evolution of materials in extreme environments, relevant to energy applications. Current understanding of the synergistic effects of variables such as high...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Xiao-Ying Yu
We will use in situ chemical imaging enabled by the microfluidic reactor SALVI to study a NAVY bilgewater emulsion model. Our main objective is to understand the evolving oil-water liquid-liquid interface. Such fundamental understanding is...
Lead Institution: State University of New York at Stony Brook
Principal Investigator: Daniel Knopf
Atmospheric ice nucleation represents one of the least understood atmospheric processes, hampering prediction of cloud processes and climate. Whereas the aerosol community has widely conducted aerosol-cloud condensation nuclei studies to evaluate...
