Possible error with sigma coordinates
Added by Johann Züger about 6 years ago
Hi,
I have some problems when using hybride sigma-pressure coordinates with int2lm_131101_2.00_clm4. Values of vcoord in the resulting NetCDF files always are in meter and not in sigma values. Maybe there is an error in routine src_lm_output.f90 in line 3206. This statment sets zvcoord to vcoord%vert_coord - in my opinion this should be vcoord%sigm_coord.
Best regards, Johann

I am afraid you need to change everything regarding ivctype=1
by your own, since using ivctype=1
is no longer recommended from int2lm_1.22
onwards (see below). Using ivctype=1
is on your own risk.
In the Documentation int2lm_1.22.htm
under 5. Changes of the Nameless it reads:
ivctype Changed the default value from 1 to 2: because ivctype=1 should not be used any more.
There is also a warning in the model
PRINT *, ' *** -------------------------------------------- ***' PRINT *, ' *** WARNING: ivctype = 1 is no longer supported ***' PRINT *, ' *** WARNING: !!! use at your own risk !!! ***' PRINT *, ' *** WARNING: defaults have been changed ***' PRINT *, ' *** WARNING: you have to define vcoord etc. ***' PRINT *, ' *** WARNING: by yourself in the namelist ***' PRINT *, ' *** -------------------------------------------- ***'
