Ice post-processing script required

[aidanheerdegen]

We have replaced the original COSIMA sync_data.sh script with the new payu syncing facility.

However the original sync script also contained some nco commands to concatenate daily ice files that are very wasteful of space as there is a lot of duplication of coordinate data:

https://github.com/COSIMA/1deg_jra55_ryf/blob/master/sync_data.sh#L87-L108

We need to duplicate the core of that functionality, perhaps in a separate script in tools, but that has the downside of requiring duplication across all the configs.

Could that functionality be rolled into the payu driver, or expressed one-line command and called directly as a userscript?

There is a related issue to install the nco dependency

At some stages sub-daily ice outputs were also concatenated using another script

We could make a package and install it as a dependency in the payu conda environment, but that seems like a fair bit of work for a small thing.

I have "installed" the om2-scripts repo in vk83.

The ice concatenation script is available at this path:

/g/data/vk83/apps/om2-scripts/concatenate_ice/concat_ice_daily.sh

I have done some testing at it works as a sync userscript
