Real Time Detection of Sodium in Size-Segregated Marine Aerosols
Abstract
The goal of this project is to develop a new capability for the chemical characterization of marine aerosols. This involves the development of an instrument to make quantitative, near real-time sodium concentration measurements on. This involves the individual size-segregated marine aerosols. The development and deployment of a single particle sodium detector would allow us to measure the size distribution of sea salt aerosols in air in a variety of sea states and to verify laboratory-derived relationships for the formation of aerosols via sea spray bubble bursting mechanisms. This information will provide a basis for relating the abundance of sea salt aerosols to remotely observable parameters reflecting the physical state of the atmosphere and surface ocean. It will also provide insight into the influence of sea salt-derived particles on the optical properties of the marine aerosol and a better understanding of how sea salt aerosols affect aerosol growth and nucleation in the marine boundary layer. Our objective was to determine the feasibility of coupling aerosol detection and sizing instrumentation with a highly sensitive spectroscopic sodium detector utilizing laser induced fluorescence. This would allow the simultaneous quantitative determination of aerosol size and sodium content.
