Molecular Scale Temperature
(symbol TM
)
</dt>
An atmospheric parameter defined by TM = (M0 /
M)T where M0 is the mean molecular weight at sea level,
M is the mean molecular weight at altitude, and T is air
temperature at altitude.
</dd>
Up to an altitude of about 90 kilometers, the molecular composition of
air is constant; thus M0 / M = 1 and T M = T. Above 90
kilometers, M0 / M is greater than unity, and T M is
greater than T. [[/a>|/a>
