Studies of the Dependence of Solute type and Concentration on the Surface Structure of Ice

Lead Institution

Purdue University

Principal Investigator

Paul Shepson

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

Lead Institution

Purdue University

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)…

Spectroscopic Analysis of Oranic Compounds in Atmospheric Aerosols

Instituto di Scienze dell'Atmosfera e del Clima

Principal Investigator

Stefano Decesari

Project type

Capability Research

A major fraction of atmospheric aerosols consists of carbonaceous matter (e.g., >50% by mass of the PM2.5 aerosol in most of the central and western U.S.). Present knowledge about the composition…
