NOTE: We've guessed that you're not using a client that supports colored tables and have tried to compensate. Low graphics mode looks much better on clients that do... we recommend switching to Netscape 3.0 or Microsoft Internet Explorer.

GOES Imager
multi-channel energy sensor

The GOES Imager is a multi-channel instrument designed to sense radiant and solar-reflected energy from sampled areas of the Earth. The multi-element spectral channels simultaneously sweep east-west and west-east along a north-to-south path by means of a two-axis mirror scan system. An imager schematic is given below.

The instrument can produce full-Earth disc images, sector images containing the edges of the Earth, and various sizes of area scans completely enclosed within the Earth scene using a new flexible scan system. A five-channel monitoring system makes it possible to produce a wide variety of image products from imager data.
