Seems the last few years amount of light in dark season is increasing (N75 W95, CYRB - Resolute Bay) We are speculating this is caused by reflection off some kind of pollutant (particulate?) trapped in upper air region.
This year (2008) it never really got dark here; it used to get pitch-black!
Wayne Davison (our upper air geek) has some interesting theories regarding this...
