They can only be on for BGC compsets (NOT SP or FATES).

Also, we configured the defaults the following ways:
- On only for CRUJRA2024 or CAM7 forcing because that is how the CESM3.0 clm6_0 simulations were run
- On only for CRUJRA2024, CRUJRA2024b, or CAM7 forcing because that is how the CESM3.0 clm6_0 simulations were run
- In contrast to above, it's turned off for other forcing options as we haven't run simulations with those configurations
- It's also only turned on for Historical periods and NOT future scenarios because we don't have CMIP7 data for them -->

Tag name: ctsm5.4.017

One-line Summary: Introduce CRUJRA2024b datm option (Greenand snow hole filled)

Purpose and description of changes
----------------------------------

Introduce CRUJRA2024b option:
- Includes corresponding changes in cdeps by updating to cdeps1.0.91
- Includes renaming of CRUJRA2024 files present in /python/ctsm/test/testinputs/expected_result_files to permit all tests to pass

Significant changes to scientifically-supported configurations
--------------------------------------------------------------

Does this tag change answers significantly for any of the following physics configurations?
(Details of any changes will be given in the "Answer changes" section below.)

[Put an [X] in the box for any configuration with significant answer changes.]

[ ] clm6_0

[ ] clm5_0

[ ] ctsm5_0-nwp

[ ] clm4_5


Bugs fixed
----------
List of CTSM issues fixed (include CTSM Issue # and description) [one per line]:
Fixes #3680 and parts of #3707
In cdeps this fixes https://github.com/ESCOMP/CDEPS/issues/382

Notes of particular relevance for users
---------------------------------------
Changes to CTSM's user interface (e.g., new/renamed XML or namelist variables):
- The default datm input dataset changes from CRUJRA2024 to CRUJRA2024b. The former has Antarctica filled and the latter has Greenland also filled.
- User may select either CRUJRA2024 or CRUJRA2024b using long compset names, e.g.
HIST_DATM%CRUJRA2024_SLND_SICE_SOCN_SROF_SGLC_SWAV_SESP
HIST_DATM%CRUJRA2024b_SLND_SICE_SOCN_SROF_SGLC_SWAV_SESP

Changes to the datasets (e.g., streams, surface or initial files):
CRUJRA2024 already had Antarctica filled and CRUJRA2024b has Greenland also filled.

Changes to documentation:
I updated from CRUJRA2024 to CRUJRA2024b where I found it mentioned.

Notes of particular relevance for developers:
---------------------------------------------
Changes to tests or testing:
In aux_cdeps I kept one CRUJRA2024 test unchanged, for which I added a CRUJRA2024b test. All others I just changed to CRUJRA2024b.

Testing summary:
----------------

[PASS means all tests PASS; OK means tests PASS other than expected fails.]

build-namelist tests (if CLMBuildNamelist.pm has changed):

derecho - OK (2 failures expected)

python testing (if python code has changed; see instructions in python/README.md; document testing done):

derecho - PASS

regular tests (aux_clm: https://github.com/ESCOMP/CTSM/wiki/System-Testing-Guide#pre-merge-system-testing):

derecho ----- OK done against ctsm5.4.016
izumi ------- OK done against ctsm5.4.015 (b4b with .016)

Answer changes
--------------

Changes answers relative to baseline: Yes

Summarize any changes to answers, i.e.,
- what code configurations: All
- what platforms/compilers: All
- nature of change: New climate over Greenland due to the new datm files; also roundoff or same climate diffs due to the submodule updates listed below

If this tag changes climate list the run(s) done to evaluate the new
climate. Preferably in https://github.com/NCAR/LMWG_dev (or give details below)
- LMWG_dev issue number(s): https://github.com/NCAR/LMWG_dev/issues/133

Other details
-------------
List any git submodules updated (cime, rtm, mosart, cism, fates, etc.):
cdeps1.0.84 --> cdeps1.0.91
cmeps1.1.24 --> cmeps1.1.29 (required for the cdeps update to work)

Note that ``--lon-type $my_lon_type`` is not necessary if your longitude is unambiguous---i.e., it's only needed if your longitude is in the range [0, 180].

- ``$my_end_year``: end year for DATM data to subset, *default between 1901 and 2014; the default CRUJRA2024 DATM data ends in 2023, while the old default GSWP3 ends in 2014; see note below about switching the default DATM data*

- ``$my_output_dir``: output directory to place the subset data and user_mods directory. This should be something specific to *just* your data for ``$my_site_name``.

You can also have the script subset land-use data. See the help (``tools/site_and_regional/subset_data --help``) for all argument options. For example, depending on your application, it may be helpful to specify a dominant PFT using ``--dompft`` and ``--pctpft`` flags. This allows you to control the PFTs that are present on your surface dataset

.. note::
This script defaults to subsetting specific surface data, land-use timeseries, and the CRUJRA2024 DATM data. It can currently only be run as-is on Derecho. If you're not on Derecho, use ``--inputdata-dir`` to specify where the top level of your CESM input data is.

Using ``--create-datm`` with GSWP3 data is no longer supported; see `CTSM issue #3269 <https://github.com/ESCOMP/CTSM/issues/3269>`_.
