ticket : #1314

Branch : dev_r4650_UKMO14.11_SETTE_OBSASM

Review : wiki:ticket/1314/Review


Implement assimilation interface SETTE test

Create a SETTE test configuration which includes observation operator and increments tests, to ensure that future NEMO developments do not break OBS and ASM.


Testing could consider (where appropriate) other configurations in addition to NVTK].

Other model configurationsNO
Processor configurations tested4x8, 8x4, 2x8, 4x4
If adding new functionality please confirm that the
New code doesn't change results when it is switched off
and ''works'' when switched on

(Answering UNSURE is likely to generate further questions from reviewers.)

'Please add further summary details here'

  • Configurations tested: Gyre, Orca2-LIM-PISCES, SAS

Bit Comparability

Does this change preserve answers in your tested standard configurations (to the last bit) ?YES
Does this change bit compare across various processor configurations. (1xM, Nx1 and MxN are recommended). Tested with the standard SETTE configs (see above) YES
Is this change expected to preserve answers in all possible model configurations?YES
Is this change expected to preserve all diagnostics?
,,''Preserving answers in model runs does not necessarily imply preserved diagnostics. ''

If you answered '''NO''' to any of the above, please provide further details:

  • Which routine(s) are causing the difference?
  • Why the changes are not protected by a logical switch or new section-version
  • What is needed to achieve regression with the previous model release (e.g. a regression branch, hand-edits etc). If this is not possible, explain why not.
  • What do you expect to see occur in the test harness jobs?
  • Which diagnostics have you altered and why have they changed?Please add details here……..

System Changes

Does your change alter namelists?YES
Does your change require a change in compiler options?NO

The namelist changes are really bug fixes. If key_diaobs is set and you provide no SST data the model will fail because of the reference namelist. Therefore I have set ln_sst and ln_reysst to default to false. I also changed the default filenames and added a sea ice default.


''Please ''summarize'' any changes in runtime or memory use caused by this change……''

No change in memory. Possible slight increase in runtime due to outputting additional observation diagnostics. But very minimal/negligible.

IPR issues

Has the code been wholly (100%) produced by NEMO developers staff working exclusively on NEMO?YES and NO

If No:

  • Identify the collaboration agreement details
  • Ensure the code routine header is in accordance with the agreement, (Copyright/Redistribution? etc).Add further details here if required……….

The developer (me) is also part of the NEMOVAR consortium.
