Ozone is formed when high energy ultra-violet radiation
from the sun breaks apart molecular oxygen. An oxygen atom then combines
with an oxygen molecule producing a new molecule with three atoms of
oxygen, ozone.

The
Microwave
Limb
Sounder
(MLS)
measures
microwave
emission
from
ozone
and
chlorine
monoxide,
a
major
ozone
destroying
radical.
Right
after
UARS
was
launched,
MLS
began
to
measure
large
concentrations
of
chlorine
monoxide
over
the
south
pole.
These

This
video
summarizes
science
and
data
obtained
by
the
Upper
Atmosphere
Research
Satellite
(UARS)
mission.
UARS
was
launched
in
1991
to
study
ozone
depletion
and
the
processes
that
control
the
stratospheric
ozone
layer.
Although
the
mission
was
intended
to
last
only
18
months,
UARS
continued
to
operate
7.5
years
after
launch
with
8
of
the
10
instruments
at
the
time
this
video
was
made.

The
Aral
Sea
is
actually
not
a
sea
at
all,
but
an
immense
fresh
water
lake.
In
the
last
thirty
years,
more
than
sixty
percent
of
the
lake
has
disappeared
because
much
of
the
river
flow
feeding
the
lake
was
diverted
to
irrigate
cotton
fields
and
rice
paddies.
Concentrations
of
salts
