Test cases for JEDI DA configurations

[aerorahul]

Description
A lot of new and exciting JEDI DA features have been added in the past few months.
JEDI-based DA for atmosphere with and without ensemble
JEDI-based DA for snow updates
JEDI-based DA for aerosol updates
JEDI-based DA for ocean and sea-ice

We would like to ensure that these capabilities are tested regularly with every update of the system where relevant. For e.g. an update in the ufs-weather-model hash would trigger all tests, but a change in the land_analysis will only likely impact snow DA, but that will be deferred to the SME.

Requirements
The developers of these systems should provide and maintain a cycled test case for each of these individual configurations. At an appropriate time, a weakly coupled test will be added combining these configurations based on the needs of the science teams.

Acceptance Criteria (Definition of Done)

• configuration for each update mentioned above
• data for supporting and running the above configurations in the global-workflow for atleast 1 and 1/2 cycled test at maximum of C96/5-deg resolution.

@guillaumevernieres should I be in on this?

@guillaumevernieres should I be in on this?

probably @AndrewEichmann-NOAA , we'll figure it out internally.

@aerorahul if it's okay with you, I will wait to prepare the aerosol case once I've been able to implement and test FGAT as described in #1930 as that will be our target configuration (assuming the atm has IAU on). I expect to test/debug this early next week.

PR #2199 adds C96_atmsnowDA.yaml. PR #1963 adds C48mx500_3DVarAOWCDA.yaml. Might either of these be leveraged to create cases CXX_atmUFSDA or CXXCYY_hybatmUFSDA. These cases would be JEDI-based DA for atmosphere without and with ensemble, respectively.

@jiaruidong2017 , where may I find the staged ICs used to run the Hera tests reported in PR #2287?. This PR ran C96_atmsnowDA with, I presume, an ensemble. If true, it seems the same ICs could be used to create C96_atmUFSDA and C96_hybatmUFSDA CI cases.

[jiaruidong2017]

@RussTreadon-NOAA you can find the ICs used in PR #2287 as below:

Thank you @jiaruidong2017 . These ICs work with the GFS v17 UFS weather model using the fractional grid global_cycle changes in PR #2262. Is this correct?

[jiaruidong2017]

@RussTreadon-NOAA Yes, it is correct.

g-w issue #2294 provides the JEDI-based DA for atmosphere with and without ensemble test requested by this issue.

We have all the named tests above. If more tests are to be added, we can open new issues.
