Abstract
The mathematical formu l ae of primary and secondary scattered light in the atmosphere including an absorption layer which was deduced by this author in the 3rd paper of this series are calculated numerically using an approximate method, replacing the integration of a continuous function by summation of a discontinuous step function.
Thus are shown the influences caused by various types of absorption layers chiefly existing in the upper part of the atmosphere, on the primary and secondary scattered light, and also on the angular distribution.
In every case of c alculation the major effect of the absorption layer is shown to decrease the secondary scattering. Curves of the vertical distribution of secondary emission are graphically shown in each case.
