Within the limitation of SBTART model, the paper is concerned with the preliminary study of the feasibility of determining total atmospheric ozone by scattered ultraviolet radiation from the clear zenith blue sky.

The results showed that the red /blue color index during twilight changed evidently with AODs in lower atmosphere. When AOD was small, there was a maximum of the radiance at 450nm in the high view elevation angle. So the sky color at the zenith is blue. However, the maximum shifted to red wavelength (about 700nm) with the fall of view elevation angle.
