This update will go into dev/14.6.0

@yuanjianz, will you also have a geos-chem PR to make run directory creation using processed GEOS-IT data an option? The current code lists it as not available.

printf "Pre-processed GEOS-IT data at C180 resolution is not yet available. Try again.\n"

Also pinging @yidant on if there are any updates for GCHP run directory creation for using processed GEOS-IT cubed sphere files.

Hi @lizziel, sure. I have a feature branch that enables processed cubed sphere GEOSIT in my forked repo and ready to do a PR. Do you want me to merge it into which branch? Also, noted that we have not finished our evaluation of processed cs GEOSIT due to some issues on Compute1. But I expect it to be soon.

Thanks @yuanjianz. You can target dev/14.6.0 for this. It is okay if we do not yet have all of the processed files ready.

Thanks for creating geoschem/geos-chem#2616. Is this PR that goes with it ready for review? It is still marked as draft.
