Calibrating yield for about 2000-2024 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. - 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.)

I'm pretty agnostic to when and where this gets brought in. Here are a few thoughts:

Talked to @ekluzek. I will bring in the alpha5.4 parameter file plus my changes onto master directly. |
