Make polarcap surface datasets in ctsm5.3.0, remove VR 1850 datasets

[ekluzek]

Alongside #2716 we need to add creating 1979,1850,2000,1979-2026 surface datasets for the ne0.POLARCAP resolution. This means adding it to the ne0 and ne120 resolution list in the gen namelist multi script for mksurfdata_esmf.

As part of this we'll remove the 1850 VR datasets as they aren't planned to be needed by CAM as explained by @adamrher

Definition of done:

• [x] Add polar grid to Makefile
• [ ] Remove creation of 1850 files for VR grids

Is this critical for a 5.3 milestone of does it just need to come in by the CESM3 release?

[ekluzek]

Always the right question to ask. In order to have a dataset for @adamrher to use in CTSM5.3 versions we might as well make it. It shouldn't be hard to add, unless we run into problems. So I suggest we do so unless it causes problems in making all the datasets. But, it's likely only needed by the release and not in 5.3.

[wwieder]

This isn't required for 5.3.0, but could be added on subsequent 5.3 tag (or else it needs to get into make_all).

Could add PLUMBER2 and NEON surface data too.

Confirming info listed here and in the grids speadsheet:

• no 1850
• yes 1979, 2000, 1979-2026
• same for ne0np4.ARCTICGRIS.ne30x8, ne0np4.ARCTIC.ne30x4, ne0np4CONUS.ne30x8, ne0np4.POLARCAP.ne30x4

[adamrher]

Yes, that's correct @slevis-lmwg. I noticed however that CONUS only has finidat entries for year 2013. Perhaps we can just replicate the POLARCAP finidat entries for CONUS?

[slevis-lmwg]

@adamrher thank you for the quick confirmation.

Let's confer with @ekluzek on the finidat question.

@ekluzek does the finidat discussion go under #2558 or other similar issue?

[slevis-lmwg]

From meeting with @ekluzek Current Makefile generates 1850 fsurdat files for VR grids. We decided to not mess with the scripts at this time and just not ./rimport the four 1850 fsurdat files. We can leave this issue open as a reminder to correct gen_mksurfdata_jobscript_multi.py code later.
