@wlin7 have you generated new initial conditions for the RRM grids?

I worked on this awhile back, but I ran into issues trying to run the RRM cases out long enough to ensure that they were properly adjusted to the new vertical grid.

We may use the atm IC from the current v3.NARRM test, which has completed 50+ years. The IC files are located on Chrysalis at /lcrc/group/e3sm/ac.qtang/E3SMv3_dev/20240905.v3.narrm.hybrid_dt.WCYCL1850.warm.seaice_ocean.chrysalis/archive/rest

@tangq those files look good for the NA grid - but we still have a test for the conus grid in e3sm_integration:

    #e3sm tests for RRM grids
    "e3sm_rrm" : {
        "tests" : (
            "SMS_D_Ln5.conusx4v1pg2_r05_IcoswISC30E3r5.F2010",
            )
        },

So we either need to update that grid or switch it to use the NA grid.

@whannah1 , good point.

Because v3.NARRM updated to the resolution northamericax4v1pg2_r025_IcoswISC30E3r5, it might make sense to 1) update this new resolution for the e3sm_rrm test on master, and 2) keep the old resolution for the test on the maint branches.

Another option is to interpolate the L72.conusx4v1pg2_r05_IcoswISC30E3r5 IC files to L80 and run multiple years to get the stable ICs and update the tests to use the new L80 ICs.

There could be other options. I am not sure which way is the best and am leaning towards the first method, i.e. 1) and 2) above.

Down the road, when v3.NARRM is finalized we can update the rrm tests on master with the final initial conditions.

    #e3sm tests for RRM grids
