In the preceding paper the author has computed the intensity of scattering at 5km level in four wavelength ranges, each of which has the partial energy equal to one fourth of the total solar energy falling on the upper limit of the earth's atmosphere. In the present paper he has investigated the same problem at 75 levels from 1km to 38km height, the interval between neighboring two levels being 500m. Moreover the total solar energy is divided into twelve wavelength ranges, each of which has the partial energy equal to one twelfth of the total. The study is restricted only to the primary scattering in the plane normal to the vertical plane passing through the sun's center in the sky dome.
Let T
0 be each level point above explained and draw a line passing through T
0 and making an angle θ
1 with a line passing T0 and the earth's center O. For convenience sake the line thus defined will be hereafter called θ
1 line. Let T
4 be the intersecting point of θ
1 line with the earth's surface or the upper limit of the earth's atmosphere, and T
1, T
2, T
3 be three points which divide the line section between T
0 and T4 into four equal lengths. Hereafter the above five points will be called in general T
n . The author has researched and compared the primary scattering intensity which originates at T
n and reaches the level point. Which is the largest of the above five intensities? He has found that the primary scattering is governed by the following four laws in the high atmosphere, concerning the position of the above discussed largest value, hereafter this position being called the maximum position.
1. The distance of the max. position from the level point increases with the height of the level point for the same wavelength, θ
1 and sun's altitude (h).
2. The distance in the same meaning as the 1st law increases with the increasing wavelength for the same level point, θ
1 and h.
3. The distance decreases with increasing θ
1 for the same wavelength, level point and h.
4. The distance increases with increasing sun's altitude (h) for the same wavelength, level point and θ
1.
