Most aerosols tend to spend only a relatively short time in the atmosphere - they tend to 'rain out' after a few years at most (unlike CO2 which can linger for 100+ years). Although that's 'natural' aerosols (like sulphur and dust etc) rather than stuff like aluminium or barium which would not normally be found in the atmosphere in the first place. They do tend to 'migrate' to the poles though (one reason why 'acid rain' - caused by sulphur emissions - was more prevalent in high latitudes and also a reason why the holes in the ozone layer occur there)
Worth noting that arctic regions are experiencing faster/greater warming than anywhere else at the moment. But whether there is any connection with the increase in NLCs I don't know.
I do know that I've yet to see any ...... although there's been some great photos of them taking by people I know in the UK. You need a clear night, away from bright lights to see them. Best time usually just after midnight.
Incidently, this may be of interest: oea.larc.nasa.gov...
