Air Mass Characterisation During EOPACE: Aerosol Composition and Concentration

Abstract

This project aims to define those aerosol properties within the littoral zone which impinge upon the performance of Navy electro-optical systems for a wide range of environmental conditions. These surface observations are being utilised to validate aerosol optical depths and limited particle size information derived from satellite imagery at multiple wavelengths. It is anticipated that these observations of aerosol composition and concentration aerosol observations will assist with the development and validation of mesoscale models incorporating aerosol sources, sinks and transport. The major objective of the current work has been to characterise the composition and concentration of the accumulation mode particles (0.05 is less than r is less than 1.5 microns), for a variety of locations and environmental conditions within the littoral zone, by means of a thermal analytical technique. Soot carbon loadings have been measured within these coastal air masses both as a cross-check on the thermal analytical analysis and as a very useful means of defining the anthropogenic input into these air masses. In addition, the impact of size-differentiated aerosol composition upon propagation at visible and infra-red wavelengths is being examined.
