scale height

[′skāl ‚hīt]
(geophysics)
A measure of the decrease of atmospheric pressure with height; when the atmospheric temperature is constant with height, the pressure varies exponentially with height, and the scale height is the height interval over which the pressure changes by a factor of 1/ e. Also known as e-folding height.
