NEMO and CICE
1

Hi All,

Would it be possible to get a login account for the NEMOCICE trac? I have one for the UM, but my login for that doesn’t work on the NEMOCICE trac. I’m just looking to browse the source to work out how the two models deal with surface fluxes.

Thanks!
Dan

Hi Dan,

Just to confirm this is the old NEMO/CICE repository used by UM coupled jobs version 8.6 and earlier. That’s definitely what you’re after - yes?

Cheers,
Ros.

Hi Ros,
I think so - but not entirely sure! I’m trying work out how some of the surface fluxes are passed to the ocean in the SMURPHS or CMIP6 runs with GC3.1 - looking at this:
Met Office (Login)
It looks like these runs were with UM 10.7, NEMO3.6_stable and CICE5.1.2 - is NEMO / CICE not what I want? If not, is it possible to browse the NEMO3.6_stable and CICE5.1.2 sources somewhere?

Thanks!
Cheers,
Dan

Hi Dan,

UM10.x suites all use the CICE repository that is available on the MOSRS - CICE Repository

NEMO is pulled from a mirror of the Paris repository. You can view the NEMO source code in the Paris NEMO Repository

Hope that helps,
Regards,
Ros.

Aha! Yes - I had been looking at the NEMO repository, but hadn’t found the CICE respository - thanks! Do you know which UKMO branches of NEMO & CICE were used for UM10.7? It’s not entirely obvious to me from the repositories! (I’m sure it must be documented somewhere!)

Thanks, Ros!

Hi Dan,

You can either checkout the u-as371 suite and look in the fcm_make_ocean -> sources section where it will tell you which version of the base NEMO & CICE code is being used and any branches.

Or from the suite repos (u-as371) these are the 2 branches:

cice_sources=fcm:cice.xm/branches/pkg/Config/vn5.1.2_GSI8.1_package_branch@163
nemo_sources=fcm:NEMO.xm/branches/UKMO/dev_r5518_GO6_package@8638

So that’s URLs:
https://code.metoffice.gov.uk/trac/cice/browser/main/branches/pkg/Config/vn5.1.2_GSI8.1_package_branch?rev=163

https://forge.ipsl.jussieu.fr/nemo/browser/branches/UKMO/dev_r5518_GO6_package?rev=8638

Hope that makes sense.
Cheers,
Ros.

That’s exactly what I was looking for - thanks, Ros!
I didn’t know how to find the sources in the suite repos - that’s very helpful!

Cheers,
Dan
