[Go-essp-tech] Proposal for global attributes for publishing of downscaled datasets on EGSF nodes

[martin.juckes at stfc.ac.uk]

Hello Galia,

One quick comment (before I go on leave): having a version number in the file which uses the same format as the publication version used in CMIP5 (which is supposed to be the date of publication and hence unknown when the file is created) is likely to cause confusion. There is already a creation_date attribute, so the proposed version number adds no information. The difficulty with "how the author describes their data" is the same as with the publication date: it depends on factors which may be beyond the control or knowledge of the person producing the data file.

Regards,
Martin

Subject: Proposal for global attributes for publishing of downscaled datasets on EGSF nodes

Dear all,

After a hiatus in our communication I would like to present to you the current draft version of global attributes to be used to describe downscaled datasets which are being published on ESG nodes. My colleagues and I took into consideration all your comments sent via email and incorporated them in this current version of the document.

We would like to ask you to look at the attributes listed in the first column (descriptions and notes are included in columns 2 and 3 - all colored in light purple) of the attached table. The brown colored column indicates the global attributes used by CORDEX currently. The last 3 columns (colored in green) indicate the global attributes proposed by Karl Taylor listed there for reference. While we took into account almost everything proposed by Karl Taylor there are still minor deviations. We also added some new attributes that we thought are needed for more detailed description of the predictor or predictand datasets - these can be seen at the bottom of the list of attributes given in the first column. The version I am attaching also contains the comments by Stephanie Legutke which she so kindly provided.

Please consider the current set of global attributes listed in column 1 and send comments at your earliest convenience. We would like to come to an agreed upon version which can be used by all soon.

Thank you for your kind consideration of this proposal and looking forward to your comments and/or additions.
Please feel free to forward to whomever might be interested in this topic.


Best regards,
Galia
