The following aspects are changes to the software infrastructure in CLM since CLM3.5.
| Update to cpl7 and scripts. |
| Remove offline and cpl6 modes. |
| Remove support for CASA model. |
| Update to datm8 atmospheric data model. |
| Add gx3v7 land mask for T31 and fv-4x5 horizontal resolutions. |
| Add gx1v6 land mask for f05, f09, and f19 horizontal resolutions. |
| Add tx1v1 land mask and 1.9x2.5_tx1v1 horizontal resolution. |
| Add in 2.5x3.33 horizontal resolution. |
| Add in T62 horizontal resolution so can run at same resolution as input datm data. |
| Allow first history tape to be 1D. |
Add ability to use own version of input datasets with CLM_USRDAT_NAME
variable. |
| Add a script to extract out regional datasets. |
| New build-namelist system with XML file describing all namelist items. |
| Add glacier_mec use-case and stub glacier model. |
| Add NCL script to time-interpolate between 1850 and 2000 for fndepdat dataset, for fndepdyn version. |
| Make default of maxpatch_pft=numpft+1 instead of 4. |
| Only output static 3D fields on first h0 history file to save space. |
| Add new fields for VOC (Volatile Organic Compounds) on surface datasets, needed for the new MEGAN VOC model. |
| Add irrigation area to mksurfdata tool (NOT used in CLM yet). |
| Add multiple elevation class option for glaciers in mksurfdata tool (NOT used in CLM yet). |
| Add ascale field to land model in support of model running on it's own grid. |
