[MITgcm-support] Assigning atmospheric CO2 levels in DIC module

[Jean-Michel Campin]

Hi Jonny,

I don't know very well pkg/dic, but it seems that, if you don't want to use 
the default value of pCO2, say, e.g., 340ppm, you will need to specify, 
in "data.dic", namelist "DIC_FORCING":
 dic_int1 = 1,
 dic_pCO2 = 340.E-6,

I imagine that, in addition to the error you reported:
> ABNORMAL END: S/R DIC_READPARMS: dic_pCO2 error 
you may have found an error message in one of the STDERR.*
with something like:
(PID.TID 0000.0001) *** ERROR *** DIC_READPARMS: cannot change default dic_pCO2 if dic_int1=0

Cheers,
Jean-Michel
