What version of the code are you using?
CESM2.2 and CESM3-beta tags
Have you made any changes to files in the source tree?
No
Describe every step you took leading up to the problem:
Updated the SST data file (in env_run.xml) without matching the grid / mesh file to the same resolution.
Describe your problem or question:
I updated the SST data file ("SSTICE_DATA_FILENAME") to one with 0.9x1.25 (f09) horizontal resolution, but neglected to change the grid file (SSTICE_GRID_FILENAME for CESM2.2 or SSTICE_MESH_FILENAME for cesm3_beta*). My model grid is an SE variable resolution grid. The model regridded the SST data from the input grid to the model grid, but because the grid file was a different resolution the SST in the model was wrong. Maybe there was an error message somewhere, but the model did not crash and I did not discover the problem, and the cause, until after many simulations (and with Adam Herrington's help).
The attached image shows the bad gridding.
I wonder if there are other places in the model this error could occur?
Could a check be included to verify that the dimensions of the grid definition file match the data file?
I have submitted this issue to ESMF directly, also.
In the meantime, I wanted to post this here to make the community aware of this possible problem in their simulations.
