- I'm not a physicist, but I am aware of the traditional Rayleigh scattering
- theory. My question to the experimentalists out there is the following:
-
- Has anybody ever checked on the quantitative contribution to the blue
- color in the sky due to the effect of ozone? My CRC tells me that ozone
- is a bluish gas, and you'd think that just as with a bluish lens, the
- light coming through would be slightly blue, so a bluish gas would make
- the light coming through slightly blue, wouldn't it? Of course, the key
- is the amount contributed by scattering versus the amount contributed
- by ozone. Since the ozone layer is so thin, maybe its effect on the
- blue sky is completely negligible (8 orders of magnitude down maybe).
- But it would be kind of fun if ozone actually played a more important
- quantitative factor. I'm afraid I don't have time to pursue this question,
- but if anyone else has ever heard or thought of this hypothesis, how
- about replying?
-
- Thanks,
