CMIP6 Data Recommendations for Southern Ocean Study

Hi,
I hope you’re well. This is Rony from Curtin University in Perth, WA. I’m reaching out to seek your advice on selecting a suitable Earth System Model for studying the Southern Ocean.

My area of interest spans from 30°S to 85°S and across all longitudes (-180° to 180°). I’ve heard that the ACCESS model was originally developed with a focus on this region, so I wanted to know if it would be a good fit for my study.

Specifically, I’m looking for CMIP6 model outputs that:

  • Have a spatial resolution of at least 0.25 degrees

  • Provide projections through to the year 2100

  • Include the following variables: SST, MLD, shortwave radiation (SWR), wind speed (WS), and sea level anomaly (SLA)

Could you kindly share your insights or suggest the most suitable models for this purpose? Also, if you could point me to reliable sources or links where I can access such datasets, I’d be very grateful.

Thanks so much for your time and support.

Hi Rony, Welcome to the ACCESS Community Forum!

I don’t have a specific answer to your question, but am wondering, do you want to run your own experiment, or analyse the output from existing CMIP6 experiments? I think the latter, but wanted to make sure.

Thanks for your reply. You’re absolutely right — I’m looking to use some of the output from existing CMIP6 experiments.
We’ve developed a machine learning model to predict future phytoplankton dynamics (up to the year 2100), and now we need to feed it with input variables from CMIP6. Our aim is to use the most suitable model output from CMIP6 that aligns with our model’s training inputs as well as the SO region.

Ahh, right, well that is interesting. @pearseb might be interested in your plans and give you some hints about data to look for.

I don’t know if you’re familiar with his research, but @tylerrohr22 has done some ML work with ocean BGC, and also did a huge study comparing CMIP6 BGC models so might be someone worth reaching out to.

ACCESS-NRI also maintains an intake catalogue which can be used as a convenient method to programmatically find and access CMIP6 data

and there are some training materials for how to use the catalogue
