To produce the hail size diagnostic output, this namelist block should be added to input.nml.

&fv_diagnostics_nml
do_hailcast = .true.
/

and this entry should be added to diag_table

"gfs_dyn", "hailcast_dhail_max", "HAILCAST_DHAIL", "fv3_history2d", "all", .false., "none", 2

If either input.nml or diag_table is not changed, it will do nothing.

Description

Add FV3-HAILCAST code with FV3/atmos_cubed_sphere for hail size diagnostic output. It will not change the answers and no library update is needed.

Issue(s) addressed

see PR #164.

Testing

It was tested on Jet and a NSSL machine - Odin with Intel compiler. No regression tests needed since it will not change the model, but just add a diagnostic output.

@ywangwof Please update the submodule .gitmodules in your ufs-weather-model branch to point to your fv3 branch. Please see example here. You need to do the same for your fv3 branch (pointing to your dycore branch).

[ywangwof]

.gitmodules was modified for both PRs. Thanks.
