It has been a while, but I finally got around to posting my LRIT images.  I am using processing from the program ImageMagick to overlay the images on a Blue Marble background.  Similar images can be found at GOES Project Science.  I contacted them about their images and they evidently have a specific program that overlays their images.  I have found that the technique that provides the best images so far involve the “screen” overlay function.  I will post the batch file for this when I get the chance.
