From a quick check of the rendered tutorial after the Markdown to reStructuredText conversion, I noticed that the visualised spherical signals as in this code snippet have an artifact / discontinuity on the meridian / line of constant longitude running around the right section of the boundary of this projection
Tanvir and I discussed this previously and I think this is due to the wrapping of the data around the longitudinal direction not being correctly handled by cartopy / matplotlib by default and can be fixed as suggested there using add_cyclic helper.
@mscroggs tagging you in case you can look in to this as part of review, thanks!
