i can't remember the exact link but there is a paper written by HM treasury called 'Aviation and the environment using economic instruments' written in 2003 together with the department for transport. Has quite a bit of data in it. There's also a section in the aviation white paper on the environment. If you're looking for anything specific pm me. I've written a few papers around the subject (although not specifically on pollution but i do look at it a few times).
There was a programme about global dimming a few weeks ago on channel four, the topic Greatme talks about.
