Using new technology, an inexpensive, high quality system for the display of digital GOES images has been developed, which is suitable for use at remote field sites. The digital data are acquired at high speed (up to 10 000 baud) over ordinary telephone lines. The system allows the display of satellite images from either the view point of the satellite or remapped into an azimuthal-equidistant map projection, which allows direct, undistorted comparison with radar displays. The images can be enhanced with several built-in algorithms, and images at several resolutions up to the limits of the GOES satellite can be displayed. Images processed with this system have proved useful for both forecasting and operational decision making in a meteorological field experiment.
