The Webster dictionary defines a satellite as a man-made object put into orbit around a celestial body, like the earth or the moon. Satellites serve a wide variety of purposes from transmission of television signals via communication satellites to guidance and tracking systems of defense satellites. For meteorologists, satellites provide a comprehensive view of the world's weather by observing weather and the environment on a scale not possible by other means.

On April 1, 1960, the nation's first weather satellite, "TIROS I" was launched into orbit. Soon after, meteorologists saw the first pictures of a midlatitude cyclone over the northeastern United States. A new era had begun. Since then, weather satellites have been launched into orbit and their capabilities have improved significantly. Today, not only do satellites observe clouds, but measure other non- visible radiation from the earth and atmosphere. This helps us to estimate such aspects as crop and soil conditions as well as monitor concentrations of atmospheric ozone and many other global characteristics.

The purpose of this module is to examine Earth observing satellites and their capabilities in greater detail, focusing on two satellite orbital groups in particular; Geostationary Operational Environmental Satellites (GOES) and Polar Orbiting Environmental Satellites (POES). Finally, this module will demonstrate how to interpret visible, infrared and water vapor channel satellite images.
