The present investigation represents part of the greet computational work on the application of the theory of scattering of light in the atmosphere, under taken in the Mathematical nepartment of the Geophysical Institute, Academy of e Sciences USSR on the basis of the theory' works out in the Department during 19 3s' , (Note: See the works of Ye.

Most of the computational methods and results obtained, as given in these articles were original and were specially do veloped in connection with the corputatiofal work undertaken, In the second part are included tables relating to various concrete applica- lions of the theory of light scattering in the atmosphere. is of eomputations in both the first and the second parts, refer ,~].1. the results to thc, case of, spherical scattering. Non-spherical scattering is a subject of special computational work, and the results relating this case will be foznulated eiewhere. She numerical cal methods employed during construction of the tables were developed by Ye. S. Kuznetsov (Articles I, II, IV, VI) and by 13. V. Ovchinskiy (Articles TV, v).
