Here's spectral cross section of ozone absorption in the visible(+NIR) range - the Chappuis band:Ĭould you explain why the effect of ozone is more important after sunset? Why doesn't this change the story during sunset, or during the day?ĭuring the day sunlight passes much smaller distances through the atmosphere, thus is absorbed less. See in particular my answer for the question at Chemistry.SE: What exact color does ozone gas have?. Ozone doesn't absorb blue light (much): on the contrary, it absorbs red light much more, thus making the sky look blue. Wikipedia states very strongly that explanations of this in terms of Rayleigh scattering are wrong, and that the real explanation is the absorption of blue light by ozone. What's the right explanation for the blue hour? And if the blue light is reemitted, then the effect of ozone should qualitatively be very similar to the effect of Rayleigh scattering, since it's just another scattering route that favors blue light, leading us back to the original puzzle. If the blue light is not reemitted, then this just amounts to having less blue light, so it can't explain why the blue hour is more blue. But it doesn't explain why that would create the effect. Why would the color go from blue to golden to blue again? However, it seems this can't be the full story, because photographers know that after sunset, there is a so-called blue hour where the color of the sky becomes a deep blue again. During the sunset, the length of atmosphere the light from the Sun has to travel through becomes so long that the blue is depleted, giving the sky a golden color. During the day, blue light from the Sun is scattered towards us from all directions, causing a blue sky. Rayleigh scattering affects blue light more. When winter comes around, we’re usually left with only the memories of our summer vacations and city trips.There's a great story about why the sky is blue during the day, and turns golden during sunsets: Play the music you love without limits for just 9.99 3.33/month.
