post-5.4.n00: New crop calendar inputs and updated params (omni02)

[samsrabin]

Description of changes

Updated crop maturity requirements and GDD20 baselines using improved scripts and CRU-JRA forcing.

Calibrating crop parameters looking at yield for about 1995-2005 while minimizing failed seasons:

• Corn: Don't change anything. It's high for 2000-2010 but looks good after that.
• Cotton: Increase max growing season length from 160 days to 270 days. Causes overwintering, so this will probably need to be reverted! But useful for now to explore how much an extreme change could help with the high failure rate.
• Rice: Revert CLM5 arooti changes.
• Soybean: It's low for this period but nothing I tried helped much. Removing mxmat helped a bit, so increase max growing season length from 150 days to 180 days. Accidentally did this for rice instead! Will revert in next crop parameter PR.
• Sugarcane: Increase max growing season length from 300 days to 360.
• Wheat: Revert CLM5 arooti changes. Need a pretty big drop in yields and this didn't do it in my test, but that was without grainfill triggering max LAI and thus much more failed crop area. (There were no crop phase parameter changes in CLM5.)

Specific notes

Contributors other than yourself, if any: None

CTSM Issues Fixed:

• Resolves Crop calendar inputs needed with CRU-JRA climate #3321

Are answers expected to change (and if so in what way)? Yes: Any CLM6 crop compset.

Any User Interface Changes (namelist or namelist defaults changes)? New:

• clm6_0 paramfile
• Non-GSWP3 stream_fldfilename_cultivar_gdds
• Non-GSWP3 stream_gdd20_seasons = .false. stream_fldFileName_gdd20_baseline.

Does this create a need to change or add documentation? Did you do so? No

Testing performed, if any:

• aux_clm in progress
• Two build-namelist tests fail; I'm assuming these aren't my fault:

1137/3396 < FAIL> <Test Id: 1137> <Desc: useFATESLUH2fileDNE>
1144/3396 < FAIL> <Test Id: 1144> <Desc: inventoryfileDNE>

@samsrabin I looked at your changes. They seem simple enough. Approving.

I have a couple comments/questions, but this looks good to go. My comments should be addressed in a possible later step. Most of the work was in creating the new datasets that you point to here. So this is deceptively simple compared to the loads of work it took you to get the datasets ready.

Meant to include some figures before submitting, but here they are for posterity:
