Scale
This diagram does not appear to have a scale; I think it needs one.

I think the units are micrometres. I've added this to the image caption on the aerosols page, but it really should be added to the diagram itself also. — Preceding unsigned comment added by 129.215.139.65 (talk) 10:35, 21 September 2011 (UTC)


 * Agreed to the need for a scale on the image. — Preceding unsigned comment added by 99.112.125.33 (talk) 15:17, 6 September 2012 (UTC)


 * Without a scale, it's almost meaningless; you can at least get the relationship. But are the smallest ones the size of beachballs?  Or the largest? And where is the a def for PM2.5??? --plaws (talk) 18:19, 25 April 2014 (UTC)
