Chemical and physical properties of single aerosol particles using a quadrupole trap
- Physical Sciences, Inc., Andover, MA (United States); and others
The importance of aerosols in controlling the chemical balance of the stratosphere has been demonstrated through studies of the polar ozone hole and polar stratospheric clouds. Our laboratory program is designed to explore the physical and chemical properties of aerosol particles under stratospheric conditions for single particles suspended in the electrodynamic field of a quadrupole trap. The goal of this work is to provide data on important stratospheric processes, with particular attention to processes resulting from increased aircraft emissions from the current subsonic fleet or a proposed fleet of supersonic aircraft. Optical methods including Mie scattering and Raman spectroscopy are used to probe the phase and composition of individual particles. Results will be presented on the freezing behavior of sulfuric acid particles.
