Available in PDF, EPUB and Kindle. Book excerpt: A Fortran computer program LOWTRAN 2 is described for calculating the transmittance of the atmosphere in the spectral region 0.25 to 28.5 micrometers at a spectral resolution of 20/cm. The program provides a choice of six atmospheric models covering seasonal and latitudinal variations from sea level to 100 km, two haze models, and accounts for molecular absoprtion, molecular scattering, and aerosol extinction. Refraction and earth curvature effects are also included. (Author)
