Jim and I would like to know from you what think are reasonable criteria for
detemining when the abiotic and biotic simulations have reached equilibrium.
Jim has suggested that a globally integrated air-sea flux less than 0.01 Pg/yr
indicates equilbrium for the abiotic DIC field. Any thoughts on this and
criteria for C-14 and the biotic run?
My inclination would be to do something like compute the time rate of change at
each grid point, take the absolute value and compute the global average. When
this average is below some epsilon, you've reached equilibrium.
