You mean that shadows should be softer when sun is closer to horizon or that shadows should be softer when turbidity is raised?
"Sun Size" in CoronaSun is not it?
I never realized sun shadows should get softer at sunset... I always thought that sun disk does not change size.... Sun light probably get's more scattered when it's in more parallel angle with atmosphere...

That's why we sometimes see huge setting sun/moon, right?
Moon appears about 1.5% smaller when it is near the horizon than when it is high in the sky
