(iv) Both HONO and HCHO are detected in abundance in
areas suffering from photochemical smog and may lead to
the acceleration of the production of smog.
(v) The effect that NO
x
from aeroplanes and lightning can have
on ozone can be quite different from NO
x
emitted from the
surface of the earth.
(xiv) The figure below shows two sets of ozone profiles taken over
Halley Bay in Antarctica during Winter/Spring.
(i) What measurement platforms are normally used to take an
ozone profile?
(ii) Why under normal conditions (August 15
th
) is the ozone
maximum at 20 km?
(iii) Describe the key processes that have contributed to the loss
of ozone by October 13
th
.
(iv) What molecules are thought to be responsible for the ozone
loss shown in the figure?
(xv) The ozone continuity equation below is a reasonable represen-
tation of the processes that controls ozone in the boundary
layer, viz
