(meteorobs) Atmospheric expansion and meteors




Hi, Tom. I asked a similar question some time back (based on a discussion of
changes in earth's atmosphere on the Satellite Observers mailing list last
year). Although I hope you'll get a direct response from The Experts on your
question, you might try checking the Web archive of meteorobs for those old
messages. Let me know if you have any trouble!
