Empty patches in the initial condition files #1103

Closed mpaiao closed 1 year ago

mpaiao commented 1 year ago

I am trying to start some simulations using prescribed initial conditions over an area that is sparsely vegetated in the Sierra Nevada. The initial condition contains patches that have no cohorts, because some of the plots indeed have no plants.

When I run ELM-FATES, it issues the following error message:

inventory nplant:   0.000000000000000E+000
 The inventory produced a cohort with <= 0 density /m2
 ENDRUN:
 ERROR in FatesInventoryInitMod.F90 at line 1001

I have the impression that there were some discussions in the past on this issue, but I couldn't find one. Is this what we want from the model, or should we allow patches to be completely bare? For the short term I can suppress the empty patches and rescale the area of the remaining patches, but my concern is that this might introduce a bias in the initial conditions...

It may have been something else that caused the problem. I am looking into it and I will update the issue (and potentially close it) depending on the results.

Closing it because I confirmed that the problem was unrelated to empty patches.
