The purpose of this topic is to discuss and plan the evaluation of ACCESS-OM3. Below I’ve summarised the evaluation metrics and diagnostics that were included in the ACCESS-OM2 description paper ( Kiss et al. 2020 ) and technical report ( Kiss et al. ). I’ve done this as a poll so that you can vote on …

Dear All, I’ve reviewed the list of observational datasets you’ve put together for evaluating OM3. Here’s a summary of what we have so far: ERSST: Version 5 is available on Gadi in the ct11 collection. We also have v3b SSH: SEALEVEL_GLO_PHY_L4_MY_008_047 Weekly and Monthly available in kj13 AVIS…

Just to note that we ( @aekiss or I) will have the old code for other figures somewhere – but we weren’t able to keep them up to date with cookbook developments, so they might need some renovation to bring back up to date. Let me know if you want me to dig them out and push them somewhere.

For wave-ice penetration – I can (soon!) provide wave penetration into the MIZ for 2013 - present with AltiKa. Going back before 2013 is possible with other instruments but I can guarantee the 2013-present period. For sea ice motion – Tian’s work showed that OSI-405c is basically as good as anythin…

Apologies @AndyHoggANU , @anton and @willrhobbs , I’ve moved the poll into my first post since, as pointed out by @Aidan , the poll was slipping down in visibility due to the post voting. Would you be able to do the poll again please?

For equatorial/tropical Pacific verification, I would suggest the following: Vertical profiles of temperature and zonal velocity compared to observations from the TAO array at key locations (e.g. 140W and 110W on the Equator). Example plots are already in COSIMA recipes (see the “Plot vertical pr…

There are also things that should be checked to catch model configuration errors in earlier stages of development, e.g. timeseries of min and max of SSH, SST, SSS to find crazy behaviour, maps of time-mean SSS restoring, conservation of water between components, etc.

Hi all, As a follow on from work done during the ACCESS-NRI CMIP7 hackathon held in Aspendale earlier in March 2024, I’m publishing here an editable table of the key metrics we want to use to evaluate ACCESS-OM3. Please feel free to edit and add more metrics, but please do not delete existing metr…

I am planning on starting a new repository to capture these notebooks soon. The new repository would initially have nominal reviews/documentation only, and be formalised later. The idea is to have a low barrier to changes whilst we are iterating and working with initial prototype model runs (which m…

Random question, but curious to know if there are ACCESS-OM3-025 run administration statistics – i.e. approximately the SU cost of running the model in ‘standard configuration’ for one model-year? If not ACCESS-OM3 then maybe ACCESS-OM2-025? Sorry for the broadside.

It would be worthwhile to save the fields required for a DOCN data ocean to drive CICE6-WW3 configurations. From @ezhilsabareesh8 ’s poster the required fields are SST SSS surface velocity melt and freeze potential mixed layer depth @lgbennetts , @NoahDay please chime in with the duration of the 0.…

Quick Update on CMIP7 Evaluation The IPCC is developing a Rapid Evaluation Framework to assess submissions for the AR7 Fast Track. Below is a table summarising the minimum requirements for participating tools, including ESMValTool and ILAMB: [Screenshot From 2024-11-20 20-53-30] Current Progress…

ACCESS-OM3 evaluation

For SSH, do you need daily values (original product) or monthly means suffice?

I think daily could be useful for calculating variability of SSH if it's not too onerous to obtain/store.
