NaN error when running the CESM2_2

[peterchu]

Hi all,

When running the CESM2_2, compset B1850MOM, resolution f05t061, ESMF report an error that "PET1600 med_methods_mod.F90:2561 ERROR: 6 nans found in Foxx_evap". How can I debug this error?

Thanks

You should write out frequent coupler history files for a start. So, HIST_OPTION = ndays, HIST_N = 1. Then you should be able to see where the NaNs are occurring. It seems to me there is likely a land/ocean mask mismatch here.

Yes, there is a grid mismatch between ocean grid and other component grids. It guess this problem might be caused by an error in tx0.66v1 grid SCRIP file. The longitude generated from this file ranges from -286 to 70. Is there any method to solve this problem?

I'm going to move this to the MOM forum and hopefully someone can address this there.

We have discontinued the use of the t061 grid, as it has been surpassed by the t232 grid.
You will need a recent CESM tag to use the new grid:

Thank you. But where can I download the t232 grid and the corresponding grid and kmt file for CICE.

And also the input data for MOM and CICE
