Project type

Capability Research

We propose to conduct studies of the relative amounts of solid and liquid water in ice as a function of temperature and ionic composition, and how solutes such as Na+ and NO3- partition into the…

Studies of Liquid Layers on Ice Surfaces

Principal Investigator

Paul Shepson

Project type

Exploratory Research

Ice and snow in nature appears to have important roles in the air chemistry of the polar region, and in temperate regions in winter. Much is presumed to occur in thin (somes single molecule thick)…

Chemical Characterization of Atmospheric Aerosols and Cloud Water using High-Resolution Mass Spectrometry and Single-Particle Microscopy

Lead Institution

University of Michigan

Principal Investigator

Kerri Pratt

Project type

Large-Scale EMSL Research

High-resolution tandem mass spectrometry and single particle microscopy analysis will be utilized to determine the organic molecular composition and size-dependent mixing state of atmospheric…
