This interim technical report describes the initial development of the SHARC radiative transfer subroutine NEMESIS Non-Equilibrium Molecular Emission and Scattering Intensity Subroutine. NEMESIS computes the enhancement of upper atmospheric molecular excited state populations due to radiative trapping. The physical processes considered include external illumination by the sun and upwelling earthshine, collisional excitation and de-excitation, radiative decay and multiple emission-absorption. A Monte Carlo procedure for simulating the multiple emission-absorption process is developed. The procedure is validated by comparison to exact solutions for the closely related cloud scattering problem. Mesosphere, Radiation, Infrared, Scattering, Monte carlo, Atmospheric, Computer programs.
