NV&EOL G/AP Aerosol Atmospheric Models

Abstract

In order to adequately model performances of E-O sensors for use on the realistic battlefield, one element required is a model for the attenuation of visible, 1.06 micrometers and IR wavelength energy in fog, hazes, rain and snow. This model should relate to the measure of how far we are capable of seeing, namely the visibility. The model we have chosen has the form of a Beer's Law extinction. The basic data for the NV&EOL G/AP Atmospheric Model has been collected during tests at Fort A. P. Hill, Virginia, Grafenwoehr and Baumholder, FRG. The data, as collected at AP Hill, has been broken into two groupings; labeled as wet and dry fog. A least square polynomial fit of order two was carried out on this atmospheric data. The fit was carried out in the log-log space relating the scattering attenuation coefficients of the 8-12 micrometers or (3-5 micrometers) region to that of the visible (.55 micrometers) region.
