[MITgcm-support] Using biogeochemical package with #define READ_PAR

[Manfredi Manizza]

Georges,

First question :

fortcom: Error: dic_fields_load.f, line 3187: This name does not have a 
type, and must have an explicit type.   [FILENAME1]
         IF ( Filename1 .NE. ' '  ) THEN
-------------^

Have you set your File1 in data.dic ?

Do you have in DIC_OPTIONS.h the option #define  READ_PAR ?

Reading your email I suspect the manual is not up to date because those 
input files have been moved into the code
for reading  data.dic rather than data.gchem.

This is what I have in data.gchem :

&GCHEM_PARM01
   useDIC=.TRUE.,
   nsubtime=1,
&

then all the files to be read are specified in data.dic

Second question :

if you are using EXF you have to comment with #undef in DIC_OPTIONS.h 
the READ_PAR line of code
and then #define USE_QSW because the solar radiation will be read by the
EXF package from the file you specificy in the file data.exf (NCEP, 
ECMWF, whatever...).
This worked for me for my polar configurations.

Generally, that value of Qsw is already masked
from sea-ice cover computed by the coupled sea-ice model.
I would go through the code carefully in the debugging phase about this 
to avoid that
you mask it twice reducing the value of Qsw (in bio_export.F) so that you
will underestimate the biological production in your computation.

I hope all I said makes sense and you will solve your problems.

Manfredi
