Paper Abstract

The atmospheric transmittance and radiance code LOWTRAN 4 has been modified to include first order scattering of sunlight into the line of sight. This scattering becomes important for wavelengths shorter than 5μm under daytime conditions. The radiance due to both aerosol and molecular scattering is combined with atmospheric extinction and thermal emission already contained in the model. A mean phase function is defined by averaging over a given aerosol size distribution, composition, and wavelength in order to simplify the calculations. A comparison of the model with observational data is presented.
