spin-up

[Sijia Chen]

Hello, everyone:
when I run spin-up of CLM5, I find something wrong in my cesm.log like Negative conc. in ch4tran. c,j,deficit (mol): 548054 1 1.0379693681609689E-003.Actually ,I run about 200years of it ,but also like this ,I don't know why? Does this affect the similation?

Those messages about the methane model are informative, the deficit is adjusted for in the methane code.

Dear Oleson,

I'm sorry, I didn't fully understand your meaning.

1. Do you mean that these contents can be ignored and the methane model will adjust automatically?
2. Does this have any direct connection with spin-up? Does it indicate a lack of equilibrium?
3. Does this mean there is an error in the atmospheric driving data? I’m really looking forward to your reply.

Let me know if you'd like any further refinements!
