Old UM-EMPIRE coupling code

Reported by: ggeppert Owned by: simon
Component: UM Model Keywords:
Cc: simon.wilson@… Platform:
UM Version:



I have been talking to Simon Wilson about the work he did with Phil Browne on coupling the UM to EMPIRE some time ago.

Simon, could you please find the old code for the coupling for me to use as a starting point to couple a current version of the UM to a similar data assimilation framework for the PARACON project.

Thank you

Hi Gernot,

I have located my old prototype EMPIRE/HadCM3 code and have successfully managed to rerun.
The run is in the umui, the runid is xhxrf. I'm currently trying to locate some documentation, but I think it's in emails that Phil and I exchanged which now have been archived, so I need to do some digging. Perhaps it'll be good to get together to discuss precisely what you want to do. Wed or
Thu of this week? (25th/26th October). How much experience do you have of the UM?

Hi Simon,

thanks for digging out the old runs.

I do not have any experience with the UM or Rose/Cylc? but Todd Jones will help me to get started with the basics some time in November. In addition to that I need a starting point for coupling a recent version of the UM to a framework similar to EMPIRE.

The new framework ( is used in the model as a library, so there is no need to accommodate a second executable as with EMPIRE.

I agree that it would be good to get together and maybe you can give me rough introduction to the UM and Rose/Cylc? and then maybe suggest a strategy for the coupling and where changes in the UM code should be made to communicate with the assimilation.

I am currently in Hamburg and will be back in Reading on the 6th November. Thursday the 9th November would work best for me to meet.

Thank you
