@gnikulin This issue has been open for 4 months, could you please give us an update when CanRCM5 will registered

[gnikulin]

@YanjunJiao , the registration was formally open on April 12 when the CORDEX-CMIP6 archiving specifications were released, sorry for some miscommunication from our side. One requirement for the registration is to provide information about planned simulations in the CORDEX-CMIP6 downscaling plan. I see that Scinocca@ has already provided such info for CanRCM5 so now we can register it.

[gnikulin]

it's fine to register

[larsbuntemeyer]

/register

[larsbuntemeyer]

The url (https://gitlab.com/cccma/canrcm) is not reachable without login, are we ok with that? (Seems to be private repo on gitlab.com)

[gnikulin]

obs, we assume a public webpage, @YanjunJiao do you have any public webpage describing CanRCM5?

[Scinocca]

@gnikulin apologies for the confusion regarding the URL for CanRCM5. I will look into this and get back to you shortly.

[gnikulin]

@Scinocca the URL can be blank now and will be updated later

[Scinocca]

@gnikulin Yes that would work. Do you need us to remove it from the post above?

[larsbuntemeyer]

Ok, i'll remove it for now! It won't end up in the CV table anyway.

[larsbuntemeyer]

@Scinocca I have the url now pointed to the public gitlab group of CCCma for now. If you have more specific link for CanRCM5, let me know!

[jesusff]

I wouldn't open so early the possibility to register a model without some openly available further info URL, even if it is a basic one. @Scinocca, any kind of resource would be OK, it doesn't need to be a very detailed description. It can be updated later on, when you have a better one. In a quick search, I found this video which I think is better than a private URL: https://mathtube.org/lecture/video/canadian-regional-climate-model . What do you think?

Also, in that video, it is suggested that you will use spectral nudging. If this is so, note the model name (source_id) must end in "-SN" (see the archiving specs at https://doi.org/10.5281/zenodo.10961069).

As a fallback option, you could even just describe in a response to this thread the basics of the model. This would be open and we could point directly to such brief description as initial further_info_url. In particular, it would be nice to clarify the main differences between between CanRCM5 and CRCM5-SN, as these seem to be related, but registration of CRCM5-SN is also pending the provision of a further_info_url.

[gnikulin]

I thought that we don't have constrains on blank further_info_url during the registration, although it's always good to have an URL from the beginning. Requesting to provide something might be not so good idea. The video found by @jesusff actually looks very good as a starting point.

Yes, if the spectral nudging is applied, source_id must include the "-SN" suffix to avoid any confusion.

Thanks, @larsbuntemeyer @jesusff and @gnikulin for the additional information. CanRCM5 and CRCM5 are completely separate efforts within the Canadian community. While both models share a common semi-Lagrangian dynamical core, each uses an independent package of physical parameterizations. As described in Scinocca et al. (2016; https://doi.org/10.1175/JCLI-D-15-0161.1), CanRCM shares the identical physics package as the atmospheric component, CanAM, of the global Canadian Earth-System Model, CanESM. That physics package is developed in-house and is independent within the global and regional modelling communities, The complete codeset of the global and regional models are housed in one shared repository. That repository can be referenced by the URL:
https://gitlab.com/cccma/canesm.
Please use this URL for CanRCM5.

Apologies for missing the need for "-SN" in the source id. Following the conventions outlined in https://doi.org/10.5281/zenodo.10961069, the model should have a source_id of "CanRCM5-SN". I will ask my colleague @YanjunJiao who created this issue to make the modification later today.

Please let me know if you need any additional information.

[gnikulin]

@Scinocca it sounds fine, basically it's up to the CORDEX modelling groups to provide the "best" URL :-)

[jesusff]

Perfect. Fine for me as well. I already modified the first post accordingly

[Scinocca]

Thanks very much.

[larsbuntemeyer]

Thanks @Scinocca for all additional info! I'll correct it in the CV!

[gnikulin]

the CV can be updated now and that's all ?

[gnikulin]

the CV has been updated so we can close this issue ?

[jesusff]

Yes, closing...
