Air Mass Characterisation during EOPACE: Aerosol Composition and Concentration
Abstract
This project aims to define those air mass characteristics which impinge upon the performance of Navy electro-optical systems for a wide range of environmental conditions within the littoral zone. En route to achieving these goals, it is not feasible to monitor the environment to the required degree of spatial and temporal resolution, and the essentially single-point estimates available from existing models will clearly be inadequate. Therefore, other methods must be established and validated, with the long-term future probably resting upon mesoscale meteorological models incorporating aerosol loadings and which, to some extent, simulate the particle dynamics. Satellite imagery is being utilised to map aerosol optical depths with improved algorithms providing some size information, although this approach depends upon satellite availability, does not work in the presence of cloud cover, and lacks any predictive capability. It is necessary to ground-truth these methods, in addition to testing the validity of their assumptions and their extrapolation to other parts of the mapped areas, thus providing comprehensive information for the development and validation of mesoscale models incorporating aerosol sources, sinks and transport.
