Measurements of aerosol composition by aircraft during the 2005 Marine Stratus Experiment
EMSL Project ID
13690
Abstract
The objective of this project is to determine the level of detail regarding the chemical composition of ambient aerosol particles needed to adequately predict the supersaturation at which these particles activate to form cloud droplets. Addressing these questions requires measurement of aerosol size distributions, size resolved aerosol composition, mixing states, and CCN spectra or CCN concentrations at several supersaturations. Previous studies have been limited by the availability of adequate data on aerosol composition. Most have either assumed a composition, or used data that is highly averaged (e.g., from filter samples or impactors that sampled for extended periods of time). Here, we propose to take advantage of the detailed data on aerosol composition that is available using an aerosol mass-spectrometer, specifically an Aerodyne Aerosol Mass Spectrometer (Aerodyne AMS) that has been developed for use on aircraft. It is proposed to install the AMS on the DOE G-1 aircraft for use during the month-long DOE ASP Marine Stratus Experiment (MASE) that is planned for July 2005.
