Molecular-scale temperature
# Molecular-scale temperature

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

    $T_{m}(z)={\frac {M_{0}}{M(z)}}\cdot {T(z)}$
    $T_m(z)$ is molecular-scale temperature at altitude z;
    $M_0$ 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.
