Dear UFS community,
Can anyone please provide some clarification on the vertical coordinate defined in the initial conditions generated by chgres_cube: gfs_data.tile7.halo0.nc? I am using the SRW-App workflow for a CONUS 25-km grid with 64 levels (npz = 64).
In that file, the vertical dimensions are defined as lev = 65 and levp = 66. I believe this is predefined by fix_am/global_hyblev.l65.txt. Are the "lev"s defined at the layer interfaces (half levels)? The only variable in the gfs_data.til7.halo0.nc file that has levp number of levels is zh. What does levp refer to here?
Ultimately, I want to simply visualize the initial conditions and I realized that the state variables at initial time are not included in the diagnostics output (fv3_history.nc).
Thanks in advance for any pointers!
