Problems reading pop forcing data CICE

Dear all,
I am trying to do a test run with CICE standalone forced with the pop_frc.gx1v3.051202.nc. It seems to read the data correctly. However, when it uses the interpolate_data (in the subroutine ocn_data_ncar) to interpolate the monthly data to the model timestep, this error occurs: error (182): floating invalid - possible uninitialized real/complex variable. Has anyone seen this before and has an idea what the reason could be?

Hi Daniel,

Is this error from within the interpolate_data subroutine? The error seems to suggest that the c1intp and/or c2intp values are not set. Those should have been set in the interp_coeff_monthly subroutine. Can you print those values to see if they are reasonable? (between 0 and 1)?

Thanks,
David

You should also make sure that the land/ocean mask is consistent with this version of the gx1 grid. This is a SOM forcing file derived from CESM and so there might be a slight mismatch here. In the CESM, we have updated the gx1 (POP) grid several times, hence the v number.

Thanks for the suggestions! The problem turned out to be that ocn_frc_m in the subroutine ocn_data_ncar_init was not allocated yet, since the call to alloc_forcing is placed in init_forcing_atmo, which is called after the ocean initialisation subroutine. I placed the call to alloc_forcing therefore in the start of the init_forcing_ocn subroutine, this seems to resolve the problem.

Hi Daniel,
may I know where did you find the data file pop_frc.gx1v3.051202.nc. I can't download the data file to start the run. Is it possible for you to attache the data file here? Thanks a lot.
Best
