An image-display technique is described that simultaneously combines three meteorological satellite images into a color-image product. The technique reveals many features of meteorological interest. It is frequently noted that interpretations of black-and-white “infrared” nighttime imagery are difficult to make when attempting to distinguish low clouds and fog from cloudfree land and ocean, thin from thick cirrus, and thick nonprecipitating clouds from nimbostratus clouds. It is found that a more-confident discrimination can be obtained between such features when the National Oceanic and Atmospheric Administration (NOAA) Advanced Very High Resolution Radiometer (AVHRR) or Nimbus Scanning Multifrequency Microwave Radiometer (SMMR) data are combined into color-image products.

The Geophysics Directorate's 8-bit multispectral color-composite image display technique has been installed on the Satellite Data Processing System at the German Military Geophysical Office in Traben-Trarbach, Germany. The technique simulates 24-bit full-color composites on 8-bit color workstations, combining image data from the NOAA multispectral Advanced Very High Resolution Radiometer. The real-time application of this technique to operational satellite data is discussed.
