[MITgcm-support] error with exf forcing 'variable not in namelist '

[Martin Losch]

Hi there,

did you get a reply? If not:

the error message comes from your compiler and means that something wrong in your namelist EXF_NML_03.
I would do this:
1. as a general rule add “,” after each entry, some compilers tolerate omitting the comma, others don’t.
2. vstress_lat_inc is a 1-D field, but vstress_lon_inc isn’t (I agree that this is confusing, but exf does not support variable grid spacing in lon-direction for the input fields that are then interpolated to the model grid), so you need to have vstress_lon_inc = 0.1,
3. remove the blank line in the namelist. That shouldn’t really matter, but who knows …

So in summary, try this for your EXF_NML_03:
 &EXF_NML_03
 vstress_lon0    = 117.575,
 vstress_lon_inc = 0.1,
 vstress_lat0    = 24.55,
 vstress_lat_inc = 165*0.1,
 vstress_nlon    = 134,
 vstress_nlat    = 165,
 &
