Question about the spin-up process for CESM2?

Hi,

I’m currently working with CESM2 at the f19_g17 resolution, using the FHIST_BGC compset. I’m planning to start with the spin-up process and was wondering how to access an existing spin-up file.

Any insights would be greatly appreciated!

Thanks!

Regarding existing initial condition files for the land model:
- For many model configurations the model is set up to find default initial condition files, so you may not have to worry about looking for those files.
- In general we recommend a new spin-up because we do not guarantee that our default initial conditions are appropriate for your purposes.
- For a new BGC spin-up, you may save computer time by starting from an existing clm initial condition file, but not necessarily and your spin-up process may be cleaner if you start the clm with the cold start option.
