International Standard Atmosphere Data

International Standard Atmosphere

The following table calculator give the international standard atmosphere vs altitude from sea level 0 m to 1,000,000 m.

The notation 1.79. - 5 signifies 1.79 x 10^-5

${\displaystyle }$${\displaystyle Z\; =\; geometric\; altitude}$
T = temperature
P = pressure
ρ = density
g = acceleration of gravity
M = molecular weight
a = velocity of sound
λ = mean free path
H = geopotential altitude.

${\displaystyle The\; U.S.\; Standard\; Atmosphere\; is\; a\; static\; atmospheric\; model\; of\; how\; the\; pressure,\; temperature,\; density,\; and\; viscosity\; of\; the\; Earth\text{'}s\; atmosphere\; change\; over\; a\; wide\; range\; of\; altitudes\; or\; elevations.\; The\; model,\; based\; on\; an\; existing\; international\; standard,\; was\; first\; published\; in\; 1958\; by\; the\; U.S.\; Committee\; on\; Extension\; to\; the\; Standard\; Atmosphere,\; and\; was\; updated\; in\; 1962,\; 1966,\; and\; 1976.\; It\; is\; largely\; consistent\; in\; methodology\; with\; the\; International\; Standard\; Atmosphere,\; differing\; mainly\; in\; the\; assumed\; temperature\; distribution\; at\; higher\; altitudes.}$
