Naval Weapons Center Version of the Atmospheric Transmittance Computer Code LOWTRAN: User's Manual and Program Listing.

Abstract

LOWTRAN is a FORTRAN computer program, developed at the U.S. Air Force Geophysics Laboratory (AFGL), which calculates the transmittance of the earth's atmosphere in the spectral region from 0.25 to 28.57 micrometers with 20 cm spectral resolution on a linear wavenumber scale. A choice of six atmosphere models covering seasonal and latitudinal variations from sea level to 100 km are available, in addition to a capability of allowing the user to input atmospheric profile or meteorological parameters of his own choosing. The program includes four aerosol models and permits either hazy or clear haze condition to be selected, in addition to the capability of selecting a particular visibility of the user's choosing. The model accounts for molecular absorption, molecular scattering, and aerosol extinction, plus atmospheric refraction and earth's curvature effects.
