Interpolate out-of-the-box initial conditions and remove expensive tests Two main changes (plus some small additional changes): 1. Removed / reworked some expensive tests 2. Interpolated all out-of-the-box initial conditions, so that the out-of-the-box version is now compatible with our current configuration. The changes from before were (a) our standard configuration now uses the gx1v7 rather than gx1v6 land mask; (b) many inactive points are now absent in memory. See ESCOMP#622 for details. - Resolves ESCOMP#312 - Partially addresses ESCOMP#275 (just a bit) Conflicts resolved: doc/ChangeLog doc/ChangeSum

| # Steps for interpolating out-of-the-box initial conditions | ||
|
|
||
| These are the steps that should be taken when interpolating (via | ||
| `init_interp`) out-of-the-box initial conditions files. This is often done | ||
| so that we'll have out-of-the-box initial conditions files that are | ||
| compatible with the current memory allocation, etc. (thus not requiring | ||
| `init_interp` to be run all the time). | ||
|
|
||
| Do the following for each initial conditions file you want to | ||
| interpolate: | ||
|
|
||
| 1. From the latest master tag, create and run a test using the | ||
| appropriate compset and resolution for this initial conditions | ||
| file. Note that there may be other options (like carbon isotopes) | ||
| that also need to be turned on. While doing this, generate | ||
| baselines. e.g., run | ||
| `SMS_Ld1.f09_g17.I1850Clm50Sp.cheyenne_intel.clm-default` or | ||
| `SMS_Ld1.f09_g17.I1850Clm50BgcCrop.cheyenne_intel.clm-ciso`, with | ||
| baseline generation. | ||
|
|
||
| - Confirm that the test points to the desired, original finidat file, | ||
| and that `use_init_interp` is .true. by default. | ||
|
|
||
| 2. Rename the `finidat_interp_dest.nc` file that was generated by this | ||
| test, giving it a name that matches the original initial conditions | ||
| file, but with a new date stamp. Move this file into place | ||
| (`$CESMDATAROOT/inputdata/lnd/clm2/initdata_map/`). | ||
|
|
||
| 3. Add global metadata to the new file, mentioning the original file, | ||
| the test used to generate this new file, the tag used to run this | ||
| test, and a summary of what is different on this new version. For | ||
| example: | ||
|
|
||
| ``` | ||
| ncatted -h -a Notes_190111,global,c,c,'Interpolated from clmi.I1850Clm50BgcCrop.1366-01-01.0.9x1.25_gx1v6_simyr1850_c171213.nc. This is the finidat_interp_dest.nc file from SMS_Ln1.f09_g17.I1850Clm50BgcCrop.cheyenne_intel, run from ctsm1.0.dev022. Updates from the previous file are: (1) uses gx1v7 rather than gx1v6; (2) many inactive points are absent.' | ||
| ``` | ||
|
|
||
| 4. Using `ncdump -h`, diff the headers of the new and old files, and | ||
| make sure that there are no unexpected differences. Especially look | ||
| for missing fields on the new file, which could indicate, for | ||
| example, that carbon isotopes were turned on in the original run but | ||
| not in your new run. | ||
|
|
||
| 5. Update `namelist_defaults_ctsm.xml` to point to the new file. | ||
|
|
||
| - Be sure to change any attributes in both the `finidat` entry and | ||
| the `init_interp_attributes` entry for this file. In particular, if | ||
| the old file had the attribute `use_init_interp=".true."`, this | ||
| should now be removed. | ||
|
|
||
| 6. Rerun the one-day test for which you generated baselines, comparing | ||
| against these baselines. Check the following: | ||
|
|
||
| - `use_init_interp` should be .false. | ||
|
|
||
| - The test should use the new `finidat` file | ||
|
|
||
| - The test should pass and be bit-for-bit with the baseline |
