The reason of this is that near the horizon we look through a very great thickness of the lower atmosphere,which is full of the larger dust particles reflecting white light,and this diluter the pure blue of the higher atmosphere seen beyond,and in the vicinity of the sun a good deal of the blue light is reflected back into space by the finer dust,thus giving a yellowish tinge to that which reaches us reflected chiefly from the coarse dust of the lower atmosphere.
