WebThe height in the atmosphere where pressure is times its value at the surface. From the law of atmospheres , (1) where P ( z) is the pressure at height z , m is the molecular mass, g is the gravitational acceleration, k is Boltzmann's constant, and T is the temperature. Therefore, (2) so the pressure scale height is (3) Law of Atmospheres http://eodg.atm.ox.ac.uk/user/grainger/research/book/protected/Chapter1.pdf

Webwhere H = RT/Mg is called the scale height of the atmosphere. Assuming an av-erage atmospheric temperature of 240 K gives the scale height of the Earth’s atmo-sphere as about 7 km. The thickness of the atmosphere is remarkably small compared to the size of the Earth — equivalently thinner than the thick ness of the peel of an apple. WebApr 8, 2024 · Models of Earth's Atmosphere (120 to 1000 Km) Atmospheric conditions encountered by a spacecraft in orbit about the Earth are important factors in space vehicle design, mission planning, and mission operations. Density is the primary atmospheric property that affects the spacecraft's orbital altitude, lifetime, and motion in the altitude … quaker instant oatmeal blueberry nutrition

Pressure Scale Height -- from Eric Weisstein

Web(8.7.1) ρ = ρ e − z / H where H = R T μ g is the scale height. It is large if the temperature is high, the gas light and the planet’s gravity feeble.
