Molecular-scale temperature

The molecular-scale temperature is the defining property of the U.S. Standard Atmosphere, 1962. It is defined by the relationship:


 * $$T_m(z)=\frac{M_0}{M(z)}\cdot{T(z)}$$


 * Tm(z) is molecular-scale temperature at altitude z;
 * M0 is molecular weight of air at sea level;
 * M(z) is molecular weight of air at altitude z;
 * T(z) is absolute temperature at altitude z.
