Investigation of the Aerosol Impact on the Surface-Atmosphere Interactions


EMSL Project ID
51866

Abstract

This project will provide a physicochemical description of individual atmospheric particles collected in the SAIL experiment, where we will conduct systematic studies of composition and physical properties of airborne particles and their deposits in the snowpack. Our goals are to (1) investigate the contribution of natural and anthropogenic sources to aerosol budget during representative atmospheric conditions, (2) characterize particle hygroscopic properties and propensities to serve as cloud condensation nuclei (CCN) and ice nucleating particles (INPs), (3) evaluate optical properties of representative particle ensembles in the areas of studies with respect to their composition and mixing state. Using complementary capabilities of chemical imaging (CI) and molecular characterization techniques, we will examine elemental and molecular composition, mixing state, size, and higher order morphology for individual particles.
