Fórmula
Atmospheric Scale Height
The scale height is the vertical distance over which atmospheric pressure decreases by a factor of *e* (about 2.718).
Formula
H = k_B T / (m g)
For Earth, H is about 8.5 km.
Ejemplo Resuelto
Earth: T = 288 K, m = 4.81e-26 kg (N2/O2 mix), g = 9.81 m/s2.
- 01H = k_B T / (m g)
- 02H = 1.381e-23 * 288 / (4.81e-26 * 9.81)
- 03H = 3.977e-21 / 4.719e-25
- 04H = 8 428 m = 8.43 km
Preguntas Frecuentes
Why does a hotter atmosphere have a larger scale height?
Higher temperature means molecules move faster and can support a thicker atmospheric column against gravity.
How does scale height affect habitability?
A very small scale height means a thin atmosphere; a large one helps retain warmth. Scale height influences atmospheric escape rates too.
What is the scale height of Mars?
About 11.1 km, larger than Earth's despite lower temperature because Mars has weaker gravity and a lighter (CO2-dominated) atmosphere.
