Abstract

Marine aerosol models have historically relied on visibility as the primary descriptor of aerosol influence on visible and infrared E/O systems. A widely used model of this type is the original Air Force Geophysics Laboratory (AFGL) LOWTRAN 3B maritime model which is based entirely on the supplied visibility. Open ocean and shore line measurements of aerosol distributions and atmospheric transmission in the .5 to 12 μm spectral band have both initiated and partially verified models employing important windspeed and relative humidity considerations. This report explores some of these considerations as seen both on aerosol extinction models in present use by the Navy community and on experimental results taken at San Nicholas Island (SNI) and on ships in the North Atlantic. The importance of properly incorporating both relative humidity and windspeed into aerosol models is shown through comparisons of calculated E/O systems detecting performance against resolved and unresolved targets.
