Ozone Mapping Spectrometer This site from NASA's Goddard
Space Flight Center allows you to access realtime ozone
data and download animations, graphics, and images of
ozone depletion and the Antarctic ozone hole. Select "Teachers"

Stratospheric
Ozone and Human Health Project
Displays reports from the United Nations Environment Program
and the World Meteorological Organization on the environmental
effects of ozone depletion. Contains reports from 1994,

The
Ozone Depletion Phenomenon What is ozone? How did researchers
discover its role in Earth's atmosphere and the devastating
consequences of its depletion? This article from the National
Academy of Sciences attempts to answer these and other related
questions.
