Dear authors,

I invite you to carefully take into account the comment of the reviewers and your answer to them in a revised version of your manuscript.

Best regards,
Marie-France

Dear authors,

I will be happy to accept your paper for final publication, granted some minor corrections, mostly in the data availability section.

Could you please copy in the data availability section the website address (https://www.esrl.noaa.gov/psd/) where the NOAA_OI_v2 data set is available. Moreover, would it be possible to give the address pointing directly to the dataset and not to the general website.
In figure 3, could you please give a reference for ‘The magenta contour shows the 0.15 isocontour of the observations averaged over years 1982–2001’ as well as the location of the data themselves (doi or website).
Moreover, CP is not in favor of papers indicating that ‘something should happen sometimes’ because this will remain like that unless some corrigendum is published. Therefore, statements like ‘will be shortly available’,‘the majority of the model simulations’ are not acceptable as such. They should be more precise! Where will be available the simulations that are not ‘the majority’?

I also identified three spellings for preindustrial, pre-industrial or Pre-industrial. Could this be checked.

Dear authors,
Please clarify the data availability section in order that the reader can easily identify where the data can be obtained. Thank you.
All the best, Marie-France.
