molecular-scale temperature

A temperature parameter TM defined by the following relation:
ams2001glos-Me23
where T is the actual "kinetic" temperature, M0 the molecular weight of air at sea level (28.966), and M the molecular weight of air at the point where the temperature is being specified.

Molecular-scale temperature has application in specifying temperatures at extremely high altitudes (
see standard atmosphere). Below about 90 km, TM = T, but above that level, TM becomes increasingly greater than T.
