This archive of ocean-color imagery produced by SeaWiFS and Aqua-MODIS contains images from 2002 to the present. The images are viewable in a variety of formats: chlorphyll concentration, sea surface temperature, aerosol index, smoke index, and many others. Yearly, seasonal, monthly, weekly, or daily images are available. Full description.

Visitors can access near-realtime measurements of ozone in the atmosphere. A full global image can be selected, or today's measurements, or ozone data over any chosen location. Archived measurements are available as far back as November 1978, and a link to an online textbook about stratospheric ozone is provided. Full description.

The ocean and atmosphere continually exchange particles and gases in a kind of ongoing "dialogue" that influences regional and global climate. This site explains the chemical link between the ocean and atmosphere. Emphasis is on the ocean's ability to store and release water vapor and carbon dioxide, both of which contribute to the greenhouse effect. Features include text, a scientific illustration, ...

This site provides background information on the effects of the Dust Bowl in the 1930s, the 1950s drought, and the 1987-1989 drought in the Great Plains of the American Midwest. It features discussions of the extent of each drought and the economic damage incurred, using text, photographs and graphic illustrations. A link to a discussion of the Palmer Drought Severity Index is included. Full description.

This webpage, one of NASA's fact sheets, describes the role of the oceans, clouds, and aerosols in moderating climate, which has resulted in less-than-expected temperature increases as carbon dioxide levels have increased. It also describes the efforts of scientists to construct computer models to understand interactions between the atmosphere and ocean, and to perform space-based oceanography using ...

This computer-generated animation depicts the Clouds and the Earth's Radiant Energy System (CERES) instrument in operation. CERES measures the energy at the top of the atmosphere and estimates energy levels in the atmosphere and at the Earth's surface. Using information from very high resolution cloud-imaging instruments on the same spacecraft, CERES also will determine cloud properties, including ... Full description.

This site provides background information about the relationship between ocean currents and surface winds. There are links to images, JPL missions and instruments, and an El Nino site. Full description.

This alphabetical list of links explains a variety of scientific phenomena. Clicking on the name of a particular phenomenon will provide the user with a written definition or description and a list of links to exhibits (another part of the site) which illustrate it. Full description.

This site provides a description and graphic representation of the Coriolis Force, with links to a video and related sites. Full description.

This activity will allow the student to look at real-time satellite, radar, and derived imagery to study the growth and development of thunderstorms. Full description.
