CESM2.1.5 UV Nudging Run Error

[Zhu Zhu]

Hello everyone,

I am trying to nudge U and V to the CAM6 in CESM2.1.5. I downloaded the MERRA2 data from NCAR RDA Dataset d313003. Then, I used the IPT tool (IPT/Meterological_Reanalysis_Data/Finite_volume_dycore/Gen_Data_f09 at master · NCAR/IPT) to interpolate and generate the nudging data. When I run the experiment at f09_g17 resolution (./create_newcase --case $CASEROOT --mach $MACH --res f09_g17 --compset B1850G --run-unsupported), nudging works normally. However, when I run it at f19_g17 resolution (./create_newcase --case $CASEROOT --mach $MACH --res f19_g17 --compset B1850G --run-unsupported), I encounter the following error:

When generating nudging data for f19 resolution, I downloaded MERRA2 data at 1.9x2.5 resolution and changed fname_grid_info and fname_phis_output in generation script (Gen_MERRA2_fv19_32L_002.csh, attached below) as follows:

set fname_grid_info = '/mnt/f/Models/CESM2/nudging_input/grid_topo/b.e20.B1850.f19_g17.release_cesm2_1_0.020.cam.i.0301-01-01-00000.nc'
set fname_phis_output = '/mnt/f/Models/CESM2/nudging_input/grid_topo/fv_1.9x2.5_nc3000_Nsw084_Nrs016_Co120_Fi001_ZR_GRNL_031819.nc'

These two files are specified in the CAM namelist (the atm_in file for the f19_g17 case is attached below), so I think the generated nudging data should be compatible with the f19_g17 case. Information about the generated nudging data is attached bellow. When running experiment, the file name are changed from 2023 to 0001 to match the model year. I have no idea why this error happen. Any suggestion is helpful. Thanks!
