atmospheric nuclear 'events'

[Les Slaback <lester.slaback@nist.gov>]

Does anyone have an estimate of the Asian nuclear inventory in comparision to the inventory of atmospheric experience we already have?  The U.S. and the old U.S.S.R. set off some pretty big weapons before it all went underground.  Is there a reason why this experience is not relevent?
