  1. Not understanding the cotton wool bit? How about clear acetate sheet (or other clear stiffish plastic) and another one in grey or with dark pen 'dots' on? Shine a torch shone through onto white paper and compare how strong the light appears. If actual particulates needed, collect particulates from a car exhaust on sticky tape or leave some (sticky side out) on a tin can etc under a rain cover but outside for a while then stick on acetate sheet and compare the light that can get through.
     
  2. Thanks for the reply. Was thinking cotton wool as in the clouds!! This is not a strong area for me! See what you mean about the acetates.
