absolute humidity
noun
(meteorology)
In
a
system
of
moist
air,
the
ratio
of
the
mass
of
water
vapor
present
to
the
volume
occupied
by
the
mixture,
that
is,
the
density
of
the
water
vapor
component.
Absolute
humidity
is
usually
expressed
in
grams
of
water
vapor
per
cubic
meter
or,
in
engineering
practice,
in
grains
per
cubic
foot.
Because
this
measure
of
atmospheric
humidity
is
not
conservative
with
respect
to
adiabatic
expansion
or
compression,
it
is
not
commonly
used
by
meteorologists.
(Also
called
vapor
concentration
and
vapor
density).
See
relative
humidity.

(meteorology) In a system of moist air, the ratio of the mass of water vapor present to the volume occupied by the mixture, that is, the density of the water vapor component. Absolute humidity is usually expressed in grams of water vapor per cubic meter or, in engineering practice, in grains per cubic foot. Because this measure of atmospheric humidity is not conservative with respect to adiabatic expansion or compression, it is not commonly used by meteorologists. (Also called vapor concentration and vapor density). See relative humidity.
The absolute humidity in the room was measured to be 20 grams per cubic meter.
