Abstract : The report describes the work involved in making modifications to the FLASH and BRITE Monte Carlo procedures and using these programs to evaluate (1) the effects of neglecting polarization on the scattered light intensities in molecular and turbid atmospheres; (2) the error involved in using plane-parallel atmospheres to represent spherical atmospheres for large zenith angles of incidence; and (3) the effect of dust layers at different altitudes on the color ratios computed for twilight conditions.
