Some of the models in the recipe require fixes, do I need to open an issue in the core? Or can I directly open a pull request? I already had them collected in a branch.

Scientific review-wise, I had people in our department making sure that the results make sense and are actually using them for their own work. Is that enough or would it be better to ask them to comment here?

Once you're done with all the technical work, I think it might be nice ask them to comment (and approve) here, to make it a bit more visible. It would be great if they could try out the new scientific review checklist.

Hello,

The description looks fine. I think we could complete it with a reference:

documentation:
  description: |
    Recipe to compute the annual mean or the seasonal mean of the maximum Eady Growth Rate (EGR;
Brian J Hoskins and Paul J Valdes. On the existence of storm-tracks. Journal of the atmospheric sciences, 47(15):1854–1864, 1990.)
   The output produces netcdf files for each model. In the seasonal means, a plot is
    produced for each specified level showing the EGR values over the North-Atlantic region.

The plots look fine, but we could adapt the color scale for values between 0 and 1.1 or so, to see better the signal over the Atlantic. But this is just a suggestion.

I would approve the merge of this recipe.

Thank you for the comments @emchamarro! Added the suggestions.

@jvegasbsc can you take a look at this, I am not sure why some tests suddenly do not pass. Other than that I would say that everything is ready now?

Merge master, I think you need #2022

[sloosvel]

It's already up do date. Do I need to do anything else to get this approved?

[jvegreg]

I got the same issues in other branches, so don't care
