This document provides a basic explanation of the process by which ozone in the stratosphere is destroyed by human-made gases (particularly chlorofluorocarbons) that have been released into the atmosphere. Additional material describes the research being conducted in Antarctica by the National Oceanic and Atmospheric Administration's (NOAA) Earth System Research Laboratory. Full description.

This collection of activities covers such topics as the greenhouse effect, the stratospheric ozone layer, filtration of incoming electromagnetic radiation, the formation of clouds, and measurement skills. Full description.

At this site, users can read a basic explanation of the greenhouse effect, which is accompanied by a diagram illustrtating the concept. Links to additional information and to related topics are included. Full description.

This collection of links to EPA information on atmospheric ozone depletion covers topics such as the causes of ozone depletion, possible effects of ultraviolet radiation and how to protect from it, information on chlorofluorocarbons in air conditioning systems and metered dose inhalers, and lists of ozone-depleting substances. Full description.

This basic explanation of the greenhouse effect is accompanied by a diagram. Full description.

This brief discussion of atmospheric ozone provides information on where this gas occurs, its harmful and beneficial effects, and the causes and possible consequences of the depletion of "good" ozone in the atmosphere. Full description.

As part of this activity, students will read and discuss information on the greenhouse effect and list important points about global warming. Tables are provided to show the most important greenhouse gases and how much their concentrations have increased since the pre-industrial era. Full description.

This document briefly discusses the two models most favored for the formation of Earth's atmosphere and compares the present-day atmosphere to the early oxygen-lacking atmosphere. Links to related topics are included. Full description.

This glossary provides an alphabetical listing of terms related to the study of atmospheric ozone. Full description.

Visitors can learn about the relatively new field of imaging spectroscopy, which allows specific absorption features, caused by chemical bonds in materials, to be mapped spatially. Topics include an introduction to the procedure, environmental applications, vegetation and biota mapping, lithologic, and mineral mapping. A set of links provides access to reports, accompanied by spectroscopic images, ... Full description.
