In CSEG we decided this is OK to bring in for cesm2_3_beta18 since the CESM coupled compsets use clm5_1. |

I'm a little confused by this last comment. Why is CESM using clm5_1 physics? I thought the whole reason for delaying the alpha17 tag was to get 5.2 datasets onto main to avoid all the source mods and workarounds needed to run a 5.2 dataset with 5.1 physics? Regardless, will the beta17 tag have dead arctic veg modifications active? |

@wwieder this is all something we'll discuss more in depth as a group tomorrow. Yes, I did the update to clm6_0 in ctsm5.2.0 and it naturally fits there -- but was it required and the best time to do it? This will come up in the future so learning here can help us down the road. At ctsm5.2.0 clm5_1 becomes deprecated (see #2379), misnamed, and misleading. A natural thing to think is that clm5_1 would use the clm5_1 surface datasets while clm6_0 uses the newer ones. So at ctsm5.2.0 I removed almost all of the "I compset" Clm51 compsets, and changed all the testing to Clm60. You can still use clm5_1 with long name compsets for "I cases" though. At ctsm5.2.0 it becomes a project for CESM to remove uses of CLM51 in compsets and tests. As you can see from #2379 it will take a while for this to go through CESM. Changes in CESM across components take awhile to happen by nature. But, ctsm5.2.0 is correct when clm5_1 in terms of use of the dead-veg. So the current CAM and CESM compsets will be fine. And that's what will be used for the coupled model testing. Part of what we were looking for on Tuesday at CSEG was to NOT require a tag that was absolutely required for cesm2_3_beta17. This still might make it in though... |

@ekluzek thank you for showing me the work that went into this PR.
Make sure CESM testing compsets with cam6 forcing are being exercised. Update NoAnthro to Clm60.
…se of a problem in the use-case changes I made
CTSM5.2 1979 fsurdat and 1979-2026 landuse ne0np4 files + two fixes Includes work by multiple people: @slevis-lmwg: new fsurdat/landuse files and corresponding infrastructure for the three so-called VR grids (ne0np4) @samsrabin: a subset_data fix @olyson: corrections to a couple of history long-names and updates to history_fields_fates.rst and history_fields_nofates.rst
