Compute density in International Standard Atmopshere

Description

This function computes the air density at a specified altitude in the Troposphere of the International Standard Atmosphere.

Usage

altitude2density(altitude = 0)

Arguments

altitude

(geopotential) altitude in meters above sealevel.

Details

\rho = \rho_0 (1 + a \frac{h}{T_0}) ^ {-\frac{g_0}{Ra}+1} with \rho_0 = 1.225 kg/m3, a = -0.0065 K/m, h geopotential altitude in meters, g_0 = 9.80665 m/s2, and R = 287.1 J/Kg/K.

Value

Numerical value or array for the density in kg/m3
