Thats not why the sun turns red, more particles will only make it dimmer, its just the air that causes it, and the larger the angle of the light, the more air it has to go thru, so the less powerfull wawelenghts filter out. Higher air pressure would make it better, but not debree

Thank you. I came here just to say this.

Also, desert dust. The Gobi, for example, makes Vancouver subsets red.

But also, air pollution has been lessening dramatically the last few decades.

Didn’t know that about the Gobi! I always learnt that around the horizon, the sunlight has to travel through more atmosphere (draw a point on a circle, then a line perpendicular to the circle and one at an angle, draw another circle to represent the atmosphere, and you can really clearly see this effect). Because of this, when the sun is low at sunrise/sunset, it excites the molecules in the atmosphere to a further extent, and it also blocks off the blue wavelengths, making the sky red. This is why at sunset, there is a gradient of colour due to the changing ‘thickness’ of the atmosphere that light is penetrating.

We don't have to wait.

Seattle had the best sunsets a few weeks ago.
