8.  creation summary:

     Values up to 1998 are from OCMIP2 values at
     http://www.ipsl.jussieu.fr/OCMIP/phase2/simulations/CFC/boundcond/cfc1112.atm

     Values from 1999 on are from http://gaslab.ucsd.edu/pub/cfchist/

     values were extended from 1999.5 to 2003.5 on Jan 25, 2007
     converting from SIO-1998 scale to SIO-1993 scale in
     order to be consistent with pre-1998 values and to not
     change pre-1998 values.

     values were extended from 2003.5 to 2008.5 on Nov 17, 2009
     converting from SIO-2005 scale to SIO-1993 scale in
     order to be consistent with pre-1998 values and to not
     change pre-1998 values.
