A new method of calculating accurate visible radiance values in the solar aureole region is derived in this study. The method interpolates between the radiance values output by a Gauss-Seidel flat atmosphere radiative transfer model using the radiative transfer equation itself. The method thereby produces accurate radiance values for arbitrary directions with only a slight increase in the required computational effort. The radiance and diffuse irradiance are then calculated for a variety of specified model atmospheres. The impact of polarization and the vertical stratification of aerosol particles is also investigated under various atmospheric conditions, and found to be relatively small under most realistic conditions. It is also found that some care must be taken when choosing the maximum aerosol radius at which to truncate the aerosol size distribution employed in the model atmosphere, to ensure that one does not exclude significant contributors to the scattered radiance field.
