Trouble generating MERRA2 target data for a nudged CAM experiment on 1.9x2.5 deg 32L grid

Describe your problem or question:
Describe every step you took leading up to the problem:

I'm trying to run a MERRA2 nudged experiment with CAM on a 1.9x2.5 degrees grid (f19_f19) with 32 levels on Derecho, and I'm following the instructions on 9. Physics modifications via the namelist — camdoc documentation, to interpolate the existing MERRA2 data (NSF NCAR GDEX Dataset Archive /d313003/1.9x2.5/) from 72 vertical levels to 32 vertical levels, to be consistent with my model levels.

Please find attached the script I modified from the existing IPT module (~/IPT/Meterological_Reanalysis_Data/Finite_volume_dycore/Gen_Data_f09/Gen_MERRA2_fv09_32L_002.orig.csh). I'm also attaching the output I get while running the csh script. The output directory has only one cam2 netcdf file for just one timestep, despite the output file seeming to have processed at least 10 netcdf files and the original netcdf files having data for 8 different time steps each. I've also attached the headers data from the netcdf output file.

Please advise as to how to generate the required target data, and if I've made the appropriate changes required in the csh script file.

If this is a port to a new machine: Please attach any files you added or changed for the machine port (e.g., config_compilers.xml, config_machines.xml, and config_batch.xml) and tell us the compiler version you are using on this machine.
Please attach any log files showing error messages or other useful information.

Thanks for writing. Have you tried using an interactive node, or running on Casper? Do the logs show any additional messages? The LOG directory and/or the Log.Gen_MERRA2.... err and out files should also show additional information on whether the files were generated successfully.

I was able to use #PBS -q casper to run on Casper.
