Correct. *The sides and bottom are in LTE optically thick
air, so no net
radiation occurs.

I didn't ask about "net" radiation, but I'm sure you are aware of
that. So let's try again. Clouds radiate from the top, but not from
the sides or the bottom?

Where did he say that? I can't find what you are referring to.

I can only suggest you re-read the thread, paying particular attention
from post #11 onwards.
