Start a run 26c with spunup land ic

[cecilehannay]

Description of the run

We planning to start a new cesm simulation with a spunup land ic. Basically, it will be similar 26a + land ic from 016 at year 58.

The restart files are: /glade/p/cesmdata/cseg/inputdata/cesm2_init/b.cesm3_cam058_mom_e.B1850MOM.f09_L32_t061.cam6_cice5.016/0058-01-01

@brianpm is going to look at the ic condition before we start the run. @olyson and @wwieder are welcome to look it too. @klindsay28 is going to provide a file + bugfix for ocean diags

Please let us know if there is any show stopper.

Please copy diag_table and MOM_tracer_registry.F90 from /glade/work/klindsay/cesm23_cases/BMOM/b.cesm3_cam058_mom_e.B1850WscMOM.ne30_L32_t061.camdev_cice5.022.clone/SourceMods/src.mom to SourceMods/src.mom, replacing b.cesm3_cam058_mom_e.B1850WscMOM.ne30_L32_t061.camdev_cice5.022.clone in diag_table with the name of your new case. diag_table adds tracer and thickness budget diagnostic terms. MOM_tracer_registry.F90 corrects a bug in one of the added diagnostics.

Do you want to include the fix for the exact restart bug?

I copied the fix that @bstephens82 developed to /glade/work/klindsay/cesm23_cases/BMOM/b.cesm3_cam058_mom_e.B1850WscMOM.ne30_L32_t061.camdev_cice5.022.clone/SourceMods/src.cam/radiation.F90.

@cecilehannay did you re-checkout my cam branch? I sent you an email saying that this cam_dev restart bug fix has been implemented on my branch.

[cecilehannay]

No, I have been using the same code base. I don't really want to change the sandbox. I prefer to include SourceMods. When we are ready to move sandbox, I will do that.

Right now, I just include: /glade/p/cesmdata/cseg/runs/cesm2_0/b.cesm3_cam058_mom_e.B1850WscMOM.ne30_L58_t061.camdev_cice5.026c/SourceMods/src.cam/radiation.F90

[adamrher]

fine by me

I took a look at /glade/p/cesmdata/cseg/inputdata/lnd/clm2/initdata_map/clmi.B1850Clm50BgcCrop.0161-01-01.0.9x1.25_gx1v7_simyr1850_c200729.nc. I don't know how to get a decent looking plot of SNOW_DEPTH(column) (I guess using cols1d_lat and cols1d_lon as coordinates). It does seem to have a lot of points >10m. Here's the distribution:

That pretty much confirms, I think, that it isn't a problem in going from the IC file to the model grid.

Thanks Brian, here is: Snow depth on vegetated column in 016 land restart file at year 58:

Same but in land restart file being used for these coupled simulations thus far:
