====================
Special Instructions
====================

 -- CMIP requires that we save the standard 6-hourly data (U, V, T, PSL) for last 30yrs of run.

 -- Have Keith Oleson check lnd diags after 10yrs for waste-heat.

	I looked at this and confirmed that air conditioning, heating, and
	wasteheat are indeed zero.  There is a very small flux (0.01 W/m2
	global) that is due to the non-zero bottom boundary condition for
	urban areas.  Nothing to worry about
	but just something to keep in mind.

per Peter Thornton:  Use this case to create 30y of hi-freq output that will
be used to run and I-case.

I-case:  yrs 1-600 AD_spinup_on
	 yr  601:  exit_AD_spinup
	 yr  602-800:  AD_spinup_off


If we are concerned about any small remaining trends in total system carbon,
we can run a parallel control case w/o any 6ka orbital or GHG forcings,
and look at the difference in total carbon to identify any remaining bias.
We could then subtract this bias from our final analysis - or at least 
we would be aware of a potential bias.
