Committee on Extension to the Standard Atmosphere has the acronym
COESA. [
implements
the mathematical representation of the 1976 COESA United States standard
lower atmospheric values. These values are absolute temperature, pressure,
density, and speed of sound for the input geopotential altitude. T

Below the geopotential altitude of 0 m (0 feet) and above the geopotential altitude of 84,852 m (approximately 278,386 feet), the function extrapolates values. It extrapolates temperature values linearly and pressure values logarithmically.

Calculate the COESA model at 1000 m with warnings for out-of-range inputs:
[T, a, P, rho] = atmoscoesa(1000) T = 281.6500 a = 336.4341 P = 8.9875e+004 rho = 1.1116
Calculate the COESA model at 1000, 11,000, and 20,000 m with errors for out-of-range inputs:
[T, a, P, rho] = atmoscoesa([1000 11000 20000], 'Error') T = 281.6500 216.6500 216.6500 a = 336.4341 295.0696 295.0696 P = 1.0e+004 * 8.9875 2.2632 0.5475 rho = 1.1116 0.3639 0.0880
