The landuse.timeseries file created with gen_CLMsrfdata cannot be used in cesm2_3_alpha016g

[Lumoss]

Hi, everyone:

I don't know if this is the right place to ask. I'm trying to create my own resolution, but the landuse.timeseries file created with gen_CLMsrfdata cannot be used in cesm2_3_alpha016g. ERROR: PCT_LAKE_MAX is not on landuse.timeseries fileERROR in surfrdMod.F90 at line 971. Maybe I should return an older version of CESM?

Thanks for looking!

Maybe the new CESM version should use mksurfdata_esmf to create surface datasets.

I'm going to move this to the land topic.

Thank you so much!

@Lumoss to use fsurdat files generated by mksurfdata_esmf with cesm2_3_alpha016g, you need code modifications mentioned here:
Coupled Sturm snow (f2000.ne30_t232.BGC_CROP_SturmSnowtk) · Issue #13 · NCAR/LMWG_dev (search for the string ctsm5.2)

A better alternative may be to generate your fsurdat files with the mksurfdata_map tool already available with cesm2_3_alpha016g.

Your suggestion is also a valid option, i.e. to return to an older cesm that is compatible with Community_Mesh_Generation_Toolkit/VRM_tools/gen_CLMsrfdata at master · ESMCI/Community_Mesh_Generation_Toolkit

Hi,

Thank you for your reply, here is a question, using mksurfdata_esmf, specifically to modify where the code? How do I use the mksurfdata_map tool already provided in cesm2_3_alpha016g? It does not seem to be the same as the mksurfdata_map tool provided by older versions of cesm.

We don't see PCT_LAKE_MAX anywhere in that tag (cesm2_3_alpha16g), so we're not sure why you are getting that error you mention in your first post.

I used this file when I ran the CONUS case earlier, and it contains PCT_LAKE_MAX.

/cesminputdata/lnd/clm2/surfdata_esmf/ctsm5.2.0/landuse.timeseries_ne0np4CONUS.ne30x8_SSP5-8.5_78_CMIP6_1850-2100_c230530.nc

To use a ctsm5.2 file, you are definitely best off running the model from the ctsm5.2.mksurfdata branch. Ctsm5.1 needs a few hacks to work with ctsm5.2 files. However, the ctsm5.2.mksurfdata branch is not supported, yet, and may or may not work for you.

So back to the previous suggestion, I think you may be best off running the mksurfdata_map tool available in your model version to generate the fsurdat and landuse files that you need. Instructions for using the tool are in the clm user's guide.

Ok, I will try. Thank you for your help and advice.
