I think the answer to a lot of this detection of different pollutants in the
atmosphere strangely ties in with the recent technical innovations in guide
star laser systems for telescopes. Apparently its now possible to use lasers
tuned so they produce a kind of dummy spot when the components of the
atmosphere interact with the radiation from space.


Lots of clever people beavering away trying to get this idea to work with
artificial radiation a bit like the way smoke alarms work, apparently.

All goes over my head!
