This simulation display how air density, air pressure and temperature vary with altitude.
$h=44.3308 - 4.94654 P^{0.190263}$ where h = geopotential altitude (km), p=actual air pressure, Pascals
However, pressure is convert to atm (1 atm= 101325 Pa).

$h=44.3308 -42.2665 D^{0.234969}$ were used to calculate density from altitude h (km). The unit for density D is $kg/m^3$

The temperature is estimated with $T(h)= 15- 6.5 *h$

[b]You can drag the dot shown in the curve to change the altitude h (or drag the slider vertically up/down)[/b]
