Chapter 2  Protecting the Ozone Layer  Web Resources

How the web can help you with this chapter:    The color images of Earth's stratospheric ozone levels, courtesy of NASA, are animated and visually stunning. Furthermore, a satellite now orbiting the Earth can provide you with daily ozone levels for most locations on the planet. Utilize web resources to bring state-of-the-art technology to your discussions of ozone depletion.

NASA (National Aeronautics and Space Administration) makes a unique contribution to our understanding of the ozone layer: the view from space. As NASA points out, "Using this big picture, scientists can build computer models that simulate how the Earth behaves. More importantly, they can use this global understanding to focus on what people care about most: what is happening in their state or region." For the definitive word, consult An Electronic Textbook on stratospheric ozone that has dozens of low- and high-resolution graphics.

Also, each fall check the NASA reference page about ozone to learn about this year's ozone hole to find:

Information about the Earth's atmosphere and the role ozone plays.



The latest ozone maps and information about NASA's Total Ozone Mapping Spectrometers (TOMS) aboard both the Earth Probe (EP) satellite and the Japanese Advanced Earth Observations Satellite (ADEOS).



NASA information on ozone, as part of their Mission to Planet Earth.



Information about Dobson units (which measure ozone).



Facts on tracking ozone from space.



NASA's Observatorium, a virtual exhibit on ozone designed for the general public.



The financial side of the picture, courtesy of the World Bank. This is one of four agencies coordinating the funds for the phase-out of substances that deplete the ozone layer.



The Consortium for International Earth Science Information Network (CIESIN), a rich source of information on the Earth and its changing environment. To find information on ozone, click "Information Systems and Resources" in the top box on the CIESIN home page and then go to "Stratospheric Ozone and Human Health Project" and "Thematic Guides: human health":
