Thanks for your work @LisaBock! The recipe runs fine with v2.6, produces the right plots, provenance is added for all produced files and the documentation looks good to me. I left a few minor comments regarding documentation.

I am no expert of the NCL diagnostics and I can only say that the added ones look good to me. I see that you have edited two shared diagnostic scripts, diag_scripts/shared/plot/xy_line.ncl and diag_scripts/shared/statistics.ncl which seem to be both used in other diagnostics and thus recipes. Could you please comment if the modifications to these 2 diagnostics would have consequences for other recipes? Should we run other recipes to check if some results of other recipes would be impacted by the changes introduced in this PR?

• I noticed that the three files None_data_citation_info.txt, None_citation.bibtex, None_provenance.xml are written to the root of output_dir. That looks a bit strange and might need to be checked.

This is probably due to an issue in esmvaltool/diag_scripts/ipcc_ar5/ch12_calc_IAV_for_stippandhatch.ncl which is used in several recipes rather than an issue introduced in this PR. I had seen this when running recipe_collins13ipcc for releases. I'll try to investigate that and open a separate issue to discuss that.
Edit: see #2756

@axel-lauer and @remi-kazeroni Thanks for your reviews!

Hopefully I adressed all you comments. Maybe you could have a second look...

Thanks for the changes @LisaBock! This PR is good to be merged. Great to have some IPCC AR6 diagnostics in the Tool 👍
