Book excerpt: The Electro-Optical Systems Atmospheric Effects Library (EOSAEL) is a library of computer codes which predict the effect of natural and battlefield gases, aerosols, smokes and dust on electro-optical systems performance. Eosael, which is divided into 20 subprograms or modules, calculates extinction coefficients, atmospheric effects on radiation propagation and contrast reduction for wavelengths in the visible, infrared and millimeter wave regions. XSCALE is the EOSAEL module which calculate visible and IR transmittance under low visibility weather conditions. Measurements of atmospheric transmission during periods of snowfall were made in the visible and IR during March and April 1985. The measurements are compared to transmission predicted by the XSCALE module. The XSCALE predictions correspond in the IR are considerably less than the measured values which suggests that the snow transmittance algorithm used in XSCALE is more accurate for transmissometers whose receiver diameters are much larger than the beam diameter. Keywords: Computer programs. (Canada).
