@ChunchengGuo NorESM1-F is now registered. I tweaked your activity_participation to include CMIP as it is expected that the required DECK simulations for this model will also be contributed. You can review the registered details at CMIP6_source_id.html. I note that we have not recorded any of the version information for any of the models, e.g. CICE rather than CICE4 for e.g. It would be useful to revise these details if you are yet to write much of the data for the models already registered

ChunchengGuo commented 5 years ago

@durack1 Thanks for your quick response.

We did perform DECK+historical simulations with NorESM1-F, however, the historical forcing is the CMIP5 not the CMIP6 forcing, which (strictly speaking) disqualifies NorESM1-F as a CMIP6 model.

We intend to upload several PMIP simulations with NorESM1-F and the reference PI experiment ONLY (e.g. no 1%CO2, 4XCO2, historical). Would this be OK?

ChunchengGuo commented 5 years ago

@durack1 I forgot to add that the versions for the model components are CAM4, CICE4, CLM4, HAMOCC5.1

Would be great if you could help implement these tweaks; thanks!

durack1 commented 5 years ago

@ChunchengGuo good question, I think all the DECK experiments are formally required, but for contributions such as this to a defined sub-MIP (PMIP) you can only do what is practical, pinging @taylor13 for this comment

For the model subversions (CAM4, CICE4 etc), did you want to update all the NorESM* models, it seems these details are missing from all 7 variants already registered

please only update NorESM1-F for now. The other NorESM models are based on different versions for some of the components - hopefully some of my colleagues will update them at some point soon.

durack1 commented 5 years ago

Sub-model version descriptions need tweaking as contained in https://github.com/WCRP-CMIP/CMIP6_CVs/issues/786#issuecomment-535216026

durack1 commented 5 years ago

@ChunchengGuo those tweaks are made, we're still missing versioning info for MICOM and CISM, but at least some improvement was made

taylor13 commented 5 years ago

It will be acceptable for you to carry out PMIP simulations with your model (which carried out the CMIP5 core experiments, but not the CMIP6 DECK) and place your output in the CMIP6 archive. In searches of the archive, your model will belong to the "CMIP6-fringe" cohort (when the cohort labels get assigned; currently all registered models belong to the "Registered" cohort.

ChunchengGuo commented 5 years ago

@taylor13 thanks for clarifying.

@durack1 according to the comment by @taylor13, it seems that we need to re-assign the cohort of NorESM1-F from "registered" to "CMIP6-fringe". May I ask you to do the tweak in the CMIP6_souce_id.html? Thanks!

durack1 commented 5 years ago

@taylor13 can you make a comment about the cohort updating timeline?

taylor13 commented 5 years ago

For now everything is "Registered". I would say some time in the next half year we might be able to transition to designating different cohorts depending on participation levels. By the way, I think before you become part of "CMIP6-fringe", I think the rule is that you should complete all of the tier 1 PMIP experiments.

ChunchengGuo commented 5 years ago

@taylor13 could we proceed with "Registered" for now if possible? Some groups in the PMIP community have been requesting data for synthesis papers with imminent deadlines..

I am not sure if we need to complete all the PMIP tier 1 experiments; according to Table 1 in the PMIP protocol paper (https://www.geosci-model-dev.net/11/1033/2018/) -

"It is not mandatory to perform all Tier 1 experiments to take part in PMIP4-CMIP6, but it is mandatory to run at least one of the PMIP4-CMIP6 entry cards."

The tier1 has five experiments, whereas the entry cards are lig127k and lgm, and we've performed the lig127ka experiment.

taylor13 commented 5 years ago

Yes, you and all other models will (for now) be "Registered". We want to get the data out there.

thanks, Karl

ChunchengGuo commented 5 years ago

OK, thanks, Karl.

Hi, do you know how to transform the grid of the tos into lat/lon grid? image

taylor13 commented 3 years ago

I am not familiar with the NorESM1-F model and don't know how to transform the coordinates.

I am interested in knowing which file the above "header" information came from. It says it was generated by CMOR, but the metadata seems a bid odd (e.g., the declared dimensions for latitude_bnds and longitude_bnds). Could you please provide the name of the file, and possibly a full header listing (including global attributes?
