Compatible CDDS Version for CMOR 3.7.3

[sykim-nims]

Hello,

I’m working on converting climate model outputs into international standard formats using CMOR. I have installed CMOR 3.7.3 with Python 3.8.17 and plan to use it within a Cylc 7-based SUITE workflow. Additionally, I intend to use MIP Convert v2.5.8.

Before proceeding, I’d like to confirm which version of CDDS is compatible with CMOR 3.7.3.

Could you provide guidance on the recommended CDDS version for this setup? Any insights would be greatly appreciated.

Thanks!

Hi @sykim-nims,

The last version of CDDS that used CMOR 3.7.3 was 2.5.10, but the changes in MIP Convert between this version and version 2.5.8 are relatively small; extra mappings for a regional modelling project in v2.5.9 and the addition of a set of mappings for eUKESM1-1 in v2.5.10.

If you are only going to use MIP Convert, i.e. not use CDDS to run it, you have the option of picking up more recent versions of CDDS.

In more recent versions of CDDS we are working towards the developments needed to produce data for the UKESM1.3 and HadGEM3-GC5 based models that are intending to submit data to CORDEX-CMIP6 CMIP7.

Which projects are you looking to process data for?

Hi Matthew,

Thank you for your response.

I am a researcher at NIMS (National Institute of Meteorological Sciences), South Korea, working in the Climate Research Team. I am currently working on the DCPP (Decadal Climate Prediction Project) using DePreSys4. For now, I am converting atmosphere, ocean, sea ice, and land data to align with CMIP6 standards.

Based on your response, it seems that I could use either CDDS 2.5.10 or a more recent version, depending on whether I plan to run MIP Convert independently or within CDDS. Would you recommend using the latest CDDS version for better compatibility, or would 2.5.10 be a more stable choice for DePreSys4 data processing?
