Also enclosed is an example of the current capabilities for animating recent satellite images in the Dept. of Atmospheric Sciences at the University of Illinois. Updated images are obtained by the department every few hours via ftp from the UNIDATA program center in Boulder Colorado. These images can then be displayed using NCSA Image. The images are 8-bit 640x350 raster images.
The enclosed satellite images are examples of the infrared images sent back from the GOES East satellite. Because the images are infrared, every pixel represents a temperature as viewed by the satellite. False color enhancement can be a useful tool when viewing certain features in these types of images. This enhancement is created by assigning a certain color to a particular temperature value(s). Two examples of color palettes demonstrating this effect were created using NCSA PalEdit and included on this disk.
