Further down in this thread is a link to an article describing how to download and stretch the light pollution map to make a layer in Google Earth.

I have a downloadable kmz file that does this for you. All you have to do is download the 1MB file and open it. It will open a light pollution layer in Google Earth. You must of course have Google Earth installed first.

I have stretched the map to cover the whole continent but the fit is best on the east coast. You'll see that in some places light pollution doesn't radiate exactly around a town's center.
