Correct bugs in UKMO branch dev_r5518_coupling_GSI7_GSI8_landice

Description (last modified by frrh)


Tim Graham states that use of dev_r5518_coupling_GSI7_GSI8_landice and it's several variants (including the UKMO GO6 package branch) in models which do not feature CICE
causes compilation failures. It should not.

The suspicion is that there are unprotected references to variables emanating from
the CICE code repository in sbccpl.F90.


Compiling a Met Office NEMO model with this (and all other) GO6 branches present and with CICE deactivated causes compilation failure in sbccpl.F90.

There appear to be undefined references to A_P, HT_P, KN_ICE and SSTFRZ, all of which appear to be variables defined by CICE code.

There is also a code error in the use of TRIM within a non-CICE block of code controlled by CPP keys.

Additionally there are chunks of code which become unnecessary once CICE is turned off. While these are, in most, but not all, cases protected by run time tests, it is impossible to leave them in the code for compilation since they reference CICE variables directly and will fail compilation.

We aim to correct matters.


Branch branches/UKMO/dev_r5518_coupling_GSI7_GSI8_landice_bitcomp revision 6651 contains the fix.

comment:1 Changed 4 years ago by frrh

Correcting the TRIM syntax (missing bracket) and inserting suitable #if defined tests on CICE interface related CPP keys in sbccpl.F90 we appear to now have a branch suitable for use regardless of whether CICE is present or not.

I have applied these fixes to

since dev_r5518_coupling_GSI7_GSI8_landice contains a reproducibility bug rendering it unsuitable for use in coupled models and should be deleted. I don not know what dev_r5518_coupling_GSI7_GSI8_landice_with_key_asminc is.

The above fix should also be applied to any UKMO GO6 package branch.

As I understand it, this branch is not intended to go into the NEMO trunk in its entirety, however there are plans to add the functionality associated with the meltponds.

Closing completed ticket. All relevant codes should now be up to date.

comment:5 Changed 3 years ago by frrh

  • Resolution set to fixed
  • Status changed from new to closed

Closing ticket since not directly destined for NEMO trunk and work has been carried out and documented under MO GMED and/or other MO systems.
