Specialty Definitions: Refractivity

Domain	Definitions
Aerospace	1. The algebraic difference between an index of refraction and unity. For the atmosphere, refractivity may be more conveniently expressed in N-units: N = (n - 1) 10E6 The deviation of the refractivity at any altitude from the usual standard profile is expressed in B-units (for radiofrequencies up to 20 kilomegacycles): B = N + 0.12h where h is altitude in feet. The deviation of the refractivity at any altitude from the gradient at which the refraction curvature of a tangential ray will match the curvature of the earth may be expressed in M- units: M = N + 0.048h where 0.048 is 10E6 divided by the radius of the earth in feet. 2. = index of refraction.This usage should be discouraged.
