Foreword.
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'
,

The entire is divided into 2 parts each of which is

the numerical the integral equation encountered in the theory of

scattering in the atmosphere for various values of the physical parameters, and
also the auxiliary tables of various designations and tables of the 'haziness'
coefficients. All tables included in this part are of inciopendan interest, but
