when i am laying out in the sun and the sky is clear(well, as clear as it gets with this permanent haze), i can see what looks like flurries coming down out of the sky. it happens all the time. i can see these flakes coming down even easier when the sun is lower in the sky. it literally looks like snow, but you cant see them except at an angle to the sun.
i dont know what this crap is, but i dont like it. it is fine enough that i am breathing it right in while i am outside.
