CMIP6-PMIP4 request

[CommonClimate]

Hi, @cisaacstern suggested that I post an issue here (blame him).

For an NSF-funded project I am trying to obtain CMIP6-PMIP4 data for the past1000 or past2k runs (1000 or 1860y long at monthly resolution), extract surface temperature (tas), compute an appropriately weighted (cos(lat)) global mean, and export a data file (netCDF or other) with this for easy re-use and sharing.

As a use case, consider this simulation on the ESGF server. Would I be able to make it ARCO by tweaking recipe.py and replacing line 500 with CMIP6.PMIP.MPI-M.MPI-ESM1-2-LR.past2k.r1i1p1f1.Amon.tas.gn, or does the script need further massaging?

In case that makes a difference, the data are split between 93 files, each representing a 20-year period.

Once I figure out this particular recipe, the idea would be to give a similar fate to other PMIP4 transient simulations. I am new to pangeo-forge, but eager to learn.

Hi @CommonClimate,

thanks for raising the issue here. I do think this is a reasonable request. Unfortunately we are not yet fully setup, so that users can just add instance_ids to the recipe, but how about I try this out in a PR and we see how that goes?

[CommonClimate]

Hi @jbusecke , that sounds fair. I need to familiarize myself with your PR process, so let me read the docs and give it a go. This will be after June 27, as I have other things to do before then. I will be in touch for sure.

[jbusecke]

Ok that sounds good. Also there are not really docs for this particular repo at this point. Happy to have a chat once you have time to work on this!

[CommonClimate]

What is a good time to chat about this? I have time tomorrow or after July 4.

[jbusecke]

I am fairly flexible. You could pick a meeting time in my calendly?

Re: extra IDs, MPI ESM 1.2 is the only model to have archived results for the past2k experiment. For past1000, both MIROC and MRI have done so:

• CMIP6.PMIP.MRI.MRI-ESM2-0.past1000.r1i1p1f1.Amon.tas.gn
• CMIP6.PMIP.MIROC.MIROC-ES2L.past1000.r1i1p1f2.Amon.tas.gn

We have managed to process your request in a new PMIP specificic repo and two of the three datasets are online and the third one is currently running. Please let me know if you can work with the data, and if all three datasets look ok we can close this issue.

[jbusecke]

🎉 the third one is done as well.

I will close this now, but please feel free to reopen when you have more requests or issues with the existing data.

Thank you @jbusecke ! We'll give these a whirl and let you know.
