undercast
Clouds seen below
Undercast describes a layer of clouds seen from above, as from an airplane or mountain peak: We flew over an undercast that stretched to the horizon.
The term mirrors overcast, which describes clouds seen from below.
In mining, an undercast is a passage that allows airflow beneath another passage without the two connecting.
