Due to compressibility, atmospheric mass gradually “thins out” with height.

Description
Density is mass (kg) per unit volume (m3).
Due to compressibility, near-surface air is more dense than that above.
This may be expressed in terms of the mean free path, or average distance a molecule travels before colliding with another molecule.
