Fix some compsets; add only clauses for ESMF use statements (1) Fix I1850Clm51BgcCrop compset (was using CLM50 instead of CLM51) - Resolves #1882 (2) Change LND_TUNING_MODE for DATM%CPLHIST compsets to use CAM tunings since these cases typically use atmosphere forcings from CAM. - Resolves #1885 (3) Add "only" clauses to ESMF use statements - Resolves #1846

Brief summary of bug
Compsets using DATM%CPLHIST mode should use the same tunings used for runs coupled to CAM, but instead have been using CRUv7 tunings.
General bug information
CTSM version you are using: master
Does this bug cause significantly incorrect results in the model's science? Yes, but only for CPLHIST cases
Configurations affected: Runs with DATM%CPLHIST mode
Details of bug
My thinking - which others at today's ctsm-software meeting support - is that CPLHIST cases are typically generated using CAM output, and so should use the same tunings as are used in actual coupled CAM runs. @olyson says that for the land spinups done for CESM2 / CMIP6 he changed the tuning mode to use these CAM tunings, so those runs were fine, but we want the out-of-the-box behavior to match what he did manually for those runs.
I will change this using a regular expression like
DATM%CPLHIST.*_CLM50. The use of.*followingCPLHISTwill allow matching the newly-proposedCPLHISTCMEPS(or something like that).The text was updated successfully, but these errors were encountered:
