Fig. 1 -- The time development of a square concentration profile injected at 305 kilofeet for particles
of mass 150. The number above each concentration profile is the time in days for that
profile, Input conditions for this calculation were: M = 150 atomic units, m = 28.97 atomic
units, A= 2.15x 1078 em, a= 1.70x1078 em, p= 1.72 x 1079 gm/cem? at 100 kilofeet,
6T
and T= 245°K,
