Lewis No = thermal diffusivity / mass diffusivity .
So, NLe = thermal boundary layer thickness/ Concentration boundary layer thickness
Physically the momentum thickness may be conceived as transverse distance by which the boundary should be displaced to compensate for the reduction in momentum of the flowing fluid on account of boundary layer formation.
Some previously called a half-value thickness or half-value layer a half-thickness. Whatever an investigator calls it, the half-value layer is the thickness a layer of a given material would have to be to reduce the intensity of radiation striking its surface by half (50%).
Stratosphere has the highest ozone concentration. It is present as the ozone layer.
The ozone layer reaches its maximum concentration in Stratosphere. It does so because of the suitable conditions.
As measured by its thickness from upper boundary to lower boundary in a downward direction, the mantle is the thickest layer of the Earth.

Thermal Layer
The boundary between the mantle and the outer core is a layer known as D". It is a thermal and chemical boundary where a change in speed of seismic waves has been noted.
Ozone concentration increases with decreasing altitude to a maximum value, then drops of to near zero at the Earth's surface. The region of high concentration is called a layer, because it covers the entire Earth, and is confined to a few kilometers in height / thickness.
Thermal Layer
Physically the momentum thickness may be conceived as transverse distance by which the boundary should be displaced to compensate for the reduction in momentum of the flowing fluid on account of boundary layer formation.

Boundary-Layer Meteorology was created in 1971.
