Hello, I’m new to croco and I’d like to know the difference between the results from using croco\_frc.nc versus croco\_blk.nc, and the difference between the results from using croco\_clm.nc versus croco\_bry.nc.

I have read the CROCO-tutos-v1.3, but I still can’t understand the difference between using different files. And I have tried different combinations, but the results didn’t seem to make a difference.
