Shields won't function at all in the lower atmospheric layers, but the phasers are operational.

The existence of a reflecting atmospheric layer was not in itself a completely new idea.

Because Aneher didn't have a thick atmospheric layer to contain the heat, at night the air cooled.

As with Earth, the top atmospheric layer, the exosphere, does not have a well defined upper boundary.

The outer atmospheric layer contained very little hydrogen and no atomic oxygen.

The atmospheric mixed layer is a zone having nearly constant potential temperature and specific humidity with height.

The depth of the atmospheric mixed layer is known as the mixing height.

The aircraft thus slows down more in higher atmospheric layers which is the very key to efficient reentry.

However, under certain meteorological conditions, atmospheric layers may form in which the temperature increases with increasing altitude.

This is the stratosphere, the second-to-last atmospheric layer before outer space.
