Atmospheric optical transmission modelling and prediction schemes
Abstract
The optical modelling of the atmosphere requires a detailed knowledge of the physical and optical properties of the atmosphere including temperature, pressure and the distribution of molecules and aerosol contituents responsible for atmospheric extinction. The major difficulty in dealing with the atmospheric aerosols is the large natural variability of their properties. Work in modelling these properties is described. The LOWTRAN code provides a moderately low spectral resolution atmospheric propagation model of both the atmospheric molecules and aerosols without extensive computer time. Recent work in developing an atmospheric radiance version of LOWTRAN, and LASER which is a version of HITRAN including continuum absorption aerosol extinction is also discussed.
