It would have to be specific particulates to do that, of which I'm not sure what could do that. What I do know is that smoke makes the sunlight appear reddish.
However, I also think the sunlight is slightly different this year. It's noticeably more intense, and we're not even in the worst part of summer yet. We are in a solar maximum, meaning there are more sun spots and more solar activity, which means the sun is putting off more light, which might explain a slight variance in the visible EMR spectrum the sun is giving off.
I believe some wild fires in the west may be obscuring the sunlight a little.

Same in the midwest.
