Canopy

In ecology, a canopy is the overhead shade and layers of foliage provided by trees and shrubs in forests and woodlands. A canopy may have many layers or may only be a single layer. The upper most layer in a forest is called crown canopy.

The transparent enclosure over the cockpit of an aircraft is also called canopy.

The word "canopy" comes from the Greek 'Konopeion' which means "a bed with mosquito netting".
