STRATOSPHERIC OZONE ..........
"It seems quite clear that the
atmosphere has only a finite capacity for absorbing Cl [chlorine]
atoms produced in the stratosphere, and that important
consequences may result." (Molina and Rowland, Nature, v.249,
June 28 1974, pp.810-812).
SOME BASIC DEFINITIONS ETC:
- HERE are
the graphs of atmospheric density, temperature and
pressure we saw in class.
- HERE is a primer on
solar radiation and UV radiation in particular (read this!)
GENERAL OZONE SCIENCE:
-
HERE is a comprehensive lecture on ozone science from NASA's Jet
Propulsion Laboratory (needs RealPlayer) (well worth reviewing!!)
- HERE is a
definition of a Dobson Unit (DU)
- HERE is the erythemal (Diffey) action
plot you saw in class (also in the primer, above)
-
UV radiation and its
effects (NASA)
- How to measure Stratospheric ozone
levels (skim this material, if interested):
- NASA has a nice outline of
ozone science -- read this!
- Here are four
classic FAQs on the ozone layer -- read as much or as little as you
wish as you wish:
- Additional,
comprehensive links are at the bottom of THIS PAGE. In particular, I would recommend:
MID LATITUDE OZONE AND UV RADIATION
UNDER NATURAL CONDITIONS:
- OZONE:
- HERE are data from
Bismark ND showing the annual ozone cycle and the
changing ozone concentrations over the past three
decades.
- HERE is the latest
ozone profile from northern Finland (if that is
too slow, then try and old one HERE).
- Order up a
satellite image of Ozone, or surface UV
intensities HERE. Order up
animations HERE.
- Find Dobson values for over
Wausau HERE
- Total global
ozone levels are HERE (global UV
radiation map is on same page).
- UV RADIATION:
- HERE is a typical mid-latitude
monthly UV index plot.
- HERE you can find UV-B
data for north central Wisconsin
- The U.S. UV
Index forecast can be found HERE.
- And HERE is a copy of the
results of the New Zealand study.
- HERE is the latest
total ozone data for the northern hemisphere.
- HERE is the long-term
ozone trend for mid-latitudes
- Information
on the UV Index and ozone, and UV Radiation in
general is available HERE
CFCs; ozone:
ANTARCTIC:
- Science:
- Data:
- HERE is the latest ozone data from
Antarctica (HERE also).
- HERE is the latest TOVS
satellite image of ozone levels in the Antarctic
(this is the latest -- if the link is too slow
then go HERE for a not-so-recent
version).
- HERE (total
column) and HERE (12-20km) are
relatively recent plots of the progress of this
year's Antarctic ozone hole (this is the latest
-- if the link is too slow then go HERE for a not-so-recent
version). And HERE is a plot of the
SIZE of the hole.
-
HERE is the size of the ozone hole over time.
- HERE is an animation
of the Antarctic Ozone Hole in 1999 (this is the
latest -- if the link is too slow then go HERE for a not-so-recent
version).
- HERE is a plot of the
area of the Antarctic ozone hole over the years.
- HERE is a plot of the
minimum levels of ozone in the Antarctic over the
years. And HERE is a longer-term
trend line.
- HERE are animations of
the Antarctic ozone hole from recent years. And HERE is another way of
viewing the phenomenon.
- HERE is a plot of UV
exposure in Antarctica with ozone decline
