how to output other variable

[qian yang]

dear all
I am running a case for simulation NPP. But I found that the onset of grass plant productivity is late. So I want to check SWI_sum 、FD_sum、t_offset these variable and find out what the problem is. But the history file do not have these variable. I want to know how to output these variables to a history file.
thank you
qian

The best way to do this is to compare to how and existing field is output to history. The key call that needs to be added is an hist_addfld call for the field at initialization. Most data modules contain an InitHistory subroutine that contains all of the hist_addfld calls. The one caveat to this is that you can only output persistent data arrays, if your fields are only local to one subroutine, you'll need to lift them to a higher level before they can be output.

Thank you for your reply. I'll try it

Do you have any suggestions? I don't know which variable to look at for this phenomenon of delayed growth, are there any other variables involved?

I suggest reading this chapter on phenology in the CLM5 technical note:

2.20. Vegetation Phenology and Turnover — ctsm release-clm5.0 documentation

The corresponding code should mostly be in:

src/biogeochem/CNPhenologyMod.F90
