Introduction to GOES: The material presented in this module is designed as a beginner's guide to the use of GOES imagery. The GOES provide frequent images at five different wavelengths, including a visible wavelength channel and four infrared channels. The satellites scan the continental U.S. every 15 min.; most of the hemisphere, from near the north pole to ~ 20S latitude, every 30 min; and scan the entire hemisphere once every three hours in their "routine" scheduling mode. Optionally, special imaging schedules are available which allow data collection at more rapid time intervals (~7.5-min and 1-min), over reduced areal sectors. Start
