@tiloz @atteggiani When I uploaded scripts from `/g/data/p66/txz599/ACCESS-ESM_tools` to [CMIP7-Input/scripts/txz599/ACCESS-ESM\_tools at 20-add-scripts-from-access-esm-tools · ACCESS-NRI/CMIP7-Input · GitHub](https://github.com/ACCESS-NRI/CMIP7-Input/tree/20-add-scripts-from-access-esm-tools/scripts/txz599/ACCESS-ESM_tools) I noticed a number of files such as

- [CMIP7-Input/scripts/txz599/ACCESS-ESM\_tools/ancil/ferret.jnl at 20-add-scripts-from-access-esm-tools · ACCESS-NRI/CMIP7-Input · GitHub](https://github.com/ACCESS-NRI/CMIP7-Input/blob/20-add-scripts-from-access-esm-tools/scripts/txz599/ACCESS-ESM_tools/ancil/ferret.jnl)
- [CMIP7-Input/scripts/txz599/ACCESS-ESM\_tools/ancil/ferret.jnl.~1~ at 20-add-scripts-from-access-esm-tools · ACCESS-NRI/CMIP7-Input · GitHub](https://github.com/ACCESS-NRI/CMIP7-Input/blob/20-add-scripts-from-access-esm-tools/scripts/txz599/ACCESS-ESM_tools/ancil/ferret.jnl.~1~)

These are [Ferret GO scripts](https://ferret.pmel.noaa.gov/Ferret/documentation/users-guide/introduction/GO-FILES). Were any of these used to process CMIP6 forcings into ACCESS-ESM1.5 input files, or were they used only for evaluation or visualization purposes? Also, what is the meaning of suffixes such as `.~1~`, `.~2~` etc.? Was this used for versioning?

Hi @paulleopardi,

we used ferret for evaluation and plotting of the various fields. This is not required for producing the forcings. Ferret renames the .jnl file every time you start it to keep a history of everything.

Cheers,
