Issue with observations of ozone, ie ESACCI-OZONE data

[MartineMichou]

When running the recipe I copy below (I could not figure out how to attach a yml file...) :

• with the original ESACCI-OZONE toz data I got from jasmin in (DU), and the CMIP6 model toz diagnostics in (m) all data are plotted, but the plot is not useful
• when changing in the ESACCI-OZONE file toz values from DU to m and changing also the unit attribute in the netcdf file the script does not work
• when changing in the ESACCI-OZONE file toz values from DU to m and letting the unit attribute at DU then I get a plot that is useful. However there are incoherences in this observation file.

Thank you for dealing with this issue. Regards Martine Michou

@MartineMichou you can attach a yaml file if you rename it to eg recipe.yml.txt - that way GH will accept the txt format; also, if you want to add inline yaml (as you did), you can format the test to appear as yaml-like with three upper backticks/backquotes and yaml like so "```yaml"

Thank you Valeriu for letting me know how to deal with a yaml file in the GitHub environment. Is my description of the issue with the ESACCI-OZONE data clear enough? Thank you. Martine
