Where is the source code of CLM45

Dear scientists of NCAR

Both CLM5 and CLM4.5 can be used in CESM2.1.3.
I can find the resource code of CLM4.0 named "src_clm40" in the directory of components/clm. But how to distinguish the source codes between CLM4.5 and CLM5.0?


I will appreciate any help from you. Thanks in advance.
Best regards,
Dayon

Unlike CLM4, CLM4.5 and CLM5 (and all future versions of CLM) use the same code base. The differences between CLM4.5 and CLM5 are captured by differences in namelist options (in the lnd_in file). There isn't an easy way to see what code applies to each version. The best you can do is to create two cases – one with CLM4.5 and one with CLM5 – and look at the differences in the lnd_in file. You will see a lot of namelist differences, and you can search the code for specific options you're interested in, to see how the code path differs for these different options.

Thanks Sacks, I will try.
