Bring in updates needed for the CESM3.0 science capability/functionality "chill". Most importantly bringing in: CN Matrix to speed up spinup for the BGC model, updated surface datasets, updated Leung 2023 dust emissions, explicit Air Conditioning for the Urban model, updates to crop calendars. For clm6_0 physics these options are now default turned on in addition to Sturm snow, and excess ice.
- manage_externals removed and replaced by git-fleximod
- Ability to handle CAM7 in LND_TUNING_MODE
Changes to defaults for clm6_0 physics:
- Urban explicit A/C turned on
- Snow thermal conductivity is now Sturm_1997
- New IC file for f09 1850
- New crop calendars
- Dust emissions is now Leung_2023
- Excess ice is turned on
- Updates to MEGAN for BVOC's
- Updates to BGC fire method
Changes for all physics versions:
- Parameter files updated
- FATES parameter file updated
- Glacier region 1 is now undefined
- Update in FATES transient Land use
- Pass active glacier (CISM) runoff directly to river model (MOSART)
- Add the option for using matrix for Carbon/Nitrogen BGC spinup
- With new surface datasets the following GLC fields have region "1" set to UNSET: glacier_region_behavior, glacier_region_melt_behavior, glacier_region_ice_runoff_behavior
- Updates to allow creating transient landuse timeseries files going back to 1700.
- Fix an important bug on soil fields that was there since ctsm5.2.0. This results in mksurfdata_esmf now giving identical answers with a change in number of processors, as it should.
- Add in creation of ne0np4.POLARCAP.ne30x4 surface datasets.
- Add version to the surface datasets.
- Remove the --hires_pft option from mksurfdata_esmf as we don't have the datasets for it.
- Remove VIC fields from surface datasets.
- Updates in PFT/LAI/soil-color raw datasets (now from the TRENDY2024 timeseries that ends in 2023), as well as two fire datasets (AG fire, peatland), and the glacier behavior dataset.
