Abstract

The study of the variation of equivalent width in a Rayleighscattering planetary atmosphere along the intensity equator and along the mirror meridian on which μ =μ0 shows that the equivalent widths decrease monotonically towards the poles, the limb and the terminator with the following characteristics: (i) the weakest lines exhibit the maximum change; (ii) the Ier component shows more change than the Iel component; (iii) the decrease towards the limb or the terminator is not as sharp as that towards the poles; (iv)Iel component shows more decrease towards the limb while Ier component shows more decrease towards the terminator; and (v) the relation W (μ,φ;μ00)= W (μ00;μ,φ) holds for the total intensity. These results are qualitatively in agreement with the observations of absorption bands in the spectra of Venus, Jupiter and Saturn.
