Thanks @apcraig ! As I noted I also have the finidat file ready for the 1950 arcticx4v1 grid, so I may want to group that with the fsurfdat file together (and these should also go into the main E3SM repo). I'll revisit at the beginning of the week.

@apcraig thanks this looks like exactly what we need to set the correct coupling frequency for the arcticx4v1_ARRM10to60E2r1 configuration

I've also got the finidat spunup file ready and staged.

^actually I see you're pointing to the 2000 year file, and we have a new 1950 one we should use here (h/t @brhillman)

HI @darincomeau. This is really just a place holder. It turns out, if fsurfdat is not set to something by default then case.setup fails. Separately, we generally set fsurfdat in our user_nl_files, so the default is overwritten. It's possible that you haven't noticed this problem for a number of reasons. It doesn't affect the case setup because it just causes preview_namelist to fail until user_nl_elm is placed in the case directory. And that is the last step of case.setup. Maybe also because you run the case setup script and don't notice some of the output. Anyway, this just fixes a case setup problem but is not meant to be a long term setting.
It's great that you have an finidat file and may even have a better fsurfdat file. And I welcome those being set in the scripts as defaults.

@darincomeau: you pointed me to this new finidat file: /lcrc/group/e3sm/data/inputdata/lnd/clm2/initdata/20221017.ICRUELM-1950.arcticx4v1pg2_ARRM10to60E2r1.anvil.elm.r.0051-01-01-00000.nc
Could we use this one in this PR and then merge?

@milenaveneziani I'll do that in step 4. below, and also update fsurdat. Well, step 4 is making the PR into E3SM master, and step 5 will be to bring those changes to this branch.

that means that I will start the new simulations right after step 3 and changing finidat in my user_nl file.

Maybe we should merge #26 and this PR soon. This will help us all setting up and running cases. We can do additional updates and merge master into this branch as they are ready. Separately, we need more pe decomp files for the 10to60 Arctic grid for ice and ocean. In particular, if several files could be added for ice between 840 and 2400 pes, that would be great. And if several files could be added for ocean between 1200 and 2048, that would be helpful too. It's a bit of a challenge to load balance the model well with pe counts being limited by these files. If this grid is more or less blessed, then I'd advocate for even more decomp files, additional ice files are probably useful below 720 and between 2400 and 6000. The ocean decomp files offer pretty good coverage, although it never hurts to have more options. FYI, I believe the decomp files can be found here, https://web.lcrc.anl.gov/public/e3sm/inputdata/ocn/mpas-o/ARRM10to60E2r1/ The ice files we're using are "220802" in that directory. Thanks. |

@apcraig : since we are rebasing to master again, I don't think we need #26 actually. |

From a slack conversation with Darin, here are the steps we have identified for E3SM-Arctic:

Sounds like a good plan. Thanks. |
