Converting coupled job to AMIP, or vice versa

[mx020105]

We would like to run a consistent set of AMIP and coupled jobs at UM8.4 with identical physics/parameterisations etc, but I've not managed to track down such an existing pair of jobs so far. Luke is running xkola, which is GA4.0 AMIP without UKCA, and Ruth Petrie at Reading has run xipvn (GC2.0 GA4.0). Just taking the difference between these two jobs on puma already flags up quite a few differences.

My question is whether it would be more straightforward to take xipvn and try to convert it to AMIP, or whether to take xkola and try to make it coupled? This task would be for a PhD student, with some assistance from myself (and hopefully Luke). Are there any guidelines written down for converting from a coupled to AMIP job?

Thanks a lot,
Amanda

We think it may be easier to convert a coupled job into an atmosphere-only job. Still, there will probably be may pitfalls.

Amanda,

I don't know if you have made any progress with this in the meantime, but I'd suggest getting in touch with one of the HadGEM3 or GC/GA development team for some guidelines.

You may able to find some jobs (and/or people to contact) from the GA trac wiki:

(This link will shortly be moved to the shared repository)

Let me know if you want me to look into this further for you.
