Abstract : This report describes same preliminary results of an effort to relate total aerosol optical depth at visible wavelengths to the visibility in the marine boundary layer (MBL). We present an atmospheric model which explains the observed height dependence of the aerosol extinction, examine aircraft and ship data from the MAGAT experiment, illustrate the influence of synoptic scale weather patterns on aerosol structure and present a simple model to relate alpha to total vertical depth. The ultimate goal of the project is to allow an estimation of IR ranges (due primarily to atmospheric water vapor density, Q) from satellite remote sensing data. A feasibility study on the concept was performed on two NPS data sets. (Author)
