GOES-15 took its first operational full disk images at 1800z on December 6, 2011. These three images show some of the imagery acquired, including the native grayscale infrared, colorized infrared, colorized infrared water vapor, and visible imagery. The orange areas of the colorized water vapor image show areas with low moisture. The dry air associated with the Santa Ana winds in California are clearly visible. GOES-15's water vapor channel has major improvements over its predecessor on GOES-11 (the previous GOES-West).
