Abstract :
It is shown that the basic classical problem of radiative transfer theory possesses the fundamental property of photometrical invariance both for the free atmosphere and when there exists a reflecting bottom to its lower boundary. The use of the new notation-photometrical invariants-allows one to represent more rationally the analytical spatial and angle structures of the radiation fields of a uniform slab. Simultaneously the algorithms of numerical modelling of radiation fields are simplified
