'ncar' ocean forcing fault

Hello,

I am attempting to force CICE6 on a global 1/10-degree tripolar grid, with a global atmosphere and ocean datasets re-gridded to that same grid.

Amongst other machine specific inputs in the ice_in file, critical to this post/help request, I believe, is that I am using atm_data_type set to 'JRA55_tx1' and ocn_data_type set to 'ncar'. This crashes with the following error (truncated):

However, when I run using atm_data_type set to 'JRA55_tx1' and ocn_data_type set to 'default', the run completes without any errors.

My first assumption, is that there must be something wrong with my ocean forcing file, but I have gone over it, and can find no faults with it. Here is what the header of that file looks like:
netcdf acom2_ocn_frcg_cice6_2005 {
dimensions:
ni = 3600 ;
nj = 2700 ;
time = UNLIMITED ; // (31 currently)

variables:
float S(time,nj,ni) ;
S:_FillValue = -2.e+16f ;
S:units = "psu" ;
S:long_name = "sea surface salinity" ;
S:coordinates = "xc yc" ;

float T(time,nj,ni) ;
T:_FillValue = -2.e+16f ;
T:units = "C" ;
T:long_name = "sea surface temperature" ;
T:coordinates = "xc yc" ;

float U(time,nj,ni) ;
U:_FillValue = -2.e+16f ;
U:units = "m/s" ;
U:long_name = "meridional surface current" ;
U:coordinates = "xc yc" ;

float V(time,nj,ni) ;
V:_FillValue = -2.e+16f ;
V:units = "m/s" ;
V:long_name = "zonal surface current" ;
V:coordinates = "xc yc" ;

double dhdx(time,nj,ni) ;
dhdx:_FillValue = -2.e+16 ;
dhdx:units = "m" ;
dhdx:long_name = "zonal sea surface slope" ;
dhdx:coordinates = "xc yc" ;

double dhdy(time,nj,ni) ;
dhdy:_FillValue = -2.e+16 ;
dhdy:units = "m" ;
dhdy:long_name = "meridional sea surface slope" ;
dhdy:coordinates = "xc yc" ;

float hblt(time,nj,ni) ;
hblt:_FillValue = -2.e+16f ;
hblt:units = "m" ;
hblt:long_name = "mixed layer depth" ;
hblt:coordinates = "xc yc" ;

float qdp(time,nj,ni) ;
qdp:_FillValue = -2.e+16f ;
qdp:units = "W/m^2" ;
qdp:long_name = "deep ocean heat flux" ;
qdp:coordinates = "xc yc" ;

int64 time(time) ;
time:long_name = "time" ;
time:cartesian_axis = "T" ;
time:calendar_type = "GREGORIAN" ;
time:units = "days since 2005-01-01 12:00:00" ;
time:calendar = "proleptic_gregorian" ;

double xc(nj,ni) ;
xc:_FillValue = NaN ;
xc:units = "degrees_east" ;

double yc(nj,ni) ;
yc:_FillValue = NaN ;
yc:units = "degrees_north" ;
} // group /

Does anyone have an idea where the problem might lie?

Thanks,
Dan

Oh, is your ocean data file on the tx1 grid? That is 360x240 grid points. CICE standalone does not interpolate.

Rats! It looks like my reply did not stick. Hopefully this one does as I would really love some help here nutting this problem out. (I'm presently in Antarctica, Casey Station and the bandwidth is pretty poor).

Thanks David.

The ocean *and* atmosphere datasets are *not* on the Tx1 grid. They are both on a 3600x2700 global tripole grid (along with bathymetry and coastal masking) which is being supplied to CICE. Again, CICE is happily working when *just* supplied the atmosphere, it is only when I attempt to 'turn on' the 'ncar' ocean dataset.
