Default Reporting of cloud

AIUI, it's supposed to be done for several levels, but what happens when
the upper levels are blocked from vision by lower ones?

You report what you can see. Conventionally; the lowest layer, the next layer of 3 oktas or more and the next layer of 5 oktas or more. Anything else that's visible is recorded but not reported.

Unless there's a CB which would otherwise not be reported. In the Synop
8 groups it's the only time when four would be reported (at least that
was the case a while ago, it may have changed since).
