Atmospheric Optical Propagation Comparisons during MAGAT-80.

Abstract

There are three atmospheric processes responsible for the degradation of the transmission of optical images and electro-optical energy: aerosol extinction, molecular absorption, and turbulent distortion (scintillation and beam wander). As a part of the Monterey Aerosol Generation and Transport experiment (MAGAT-80), light transmission characteristics (refractive-index) structure function parameter, C squared sub N, and total extinction coefficient were measured optically on a 13.3 km path across Monterey Bay. C squared sub N and can also be calculated from micrometeorological data (aerosol spectra, turbulence and mean meteorological parameters). This report is a compilation of the preliminary analysis of path-averaged (aircraft) and midpoint (ship) micrometeorological data, including calculations of the relevant optical parameters for comparison with the optical measurements.
