Abstract

Radiative transfer in atmosphere with spherical symmetry dependence of indexes of scattering, absorption, etc., in the presence of source of radiation with axial symmetry (intensive beam, sun, etc.) is studied. Thus the problem of radiative transfer as a whole has cylindrical symmetry. Contrary to the plane or spherical problems, there is no known simple approximations for cylindrical symmetry, similar to well known Schwarzschild-Schuster or Eddington's approximations. We suggest approximation of such kind for radiative transfer problem with cylindrical symmetry. It might be used as a second iteration for the plane approximation for the secondary sources. The simplest case with isotropic conservative scattering near the terminator is presented as example.
