Another colorful mix of infrared images taken at different wavelengths and added together. The blue component shows infrared light reflected from the surface of the earth. Green is mostly from middle level clouds. The darker each color, the warmer. Red is the infrared emission from water vapor in the atmosphere. The white areas represent the highest, coldest clouds in the atmosphere - along weather fronts, and the tops of thunderstorms in the tropics.
The relatively warm land areas of Mexico and the Baja peninsula (compared to the cooler ocean waters) make them stand out quite sharply in the upper right portion of the image.
The blackness of space in the background is also false - it would
appear bright white in these infrared images where light colors indicate
cold. Artistic license, I guess. (Original images courtesy NASA-Goddard
