- jjtheblunt 4y agois there a citation for that? the reason i ask is the parent comment talks about the scattering of light at sharp incidence levels favoring certain wavelengths, with the reds being what naturally is dominant at dusk and dawn light-hitting-atmosphere angles. https://www.metoffice.gov.uk/weather/learn-about/weather/optical-effects/why-is-the-sunset-red https://www.metoffice.gov.uk/weather/learn-about/weather/opt...
- kadoban 4y agoLooked through a few pages, this one I think explains it fairly well https://demos.smu.ca/index.php/demos/astronomy/35-red-sunsets https://demos.smu.ca/index.php/demos/astronomy/35-red-sunset... The answer it gives is more of a combination of what I thought and what the parent said, tl;dr version: scattering both due to just normal oxygen and nitrogen composition of the air and also pollutants (which I think dust would also qualify, though most things I could find that specified were talking more about sulfur compounds).
