The colorized infrared images are considered "enhanced" because they contain colors that mark certain key temperature ranges. IR images are often colorized to bring out details in cloud patterns. Individual forecasters may apply different color palettes to the imagery. In the colorized imagery shown here, gray is relatively warm, blues cooler, and red indicates clouds that are the coldest, tallest, and most likely to produce rain.
The 10.3 μm “clean” infrared window band is less sensitive than other infrared window bands to water vapor absorption, and therefore improves atmospheric moisture corrections, aids in cloud and other atmospheric feature identification/classification, estimation of cloudtop brightness temperature and cloud particle size, and surface property characterization in derived products. Infrared satellite images are used by meteorologists to determine where clouds are, but more importantly, how the clouds are moving. Read more at NOAA.
