Visible Wavelengths | | This image is the equivalent of taking a black and white photo of the earth. The bright areas show where the sun is being reflected back into space as a result of clouds or snow cover. Clouds and snow show up white. The thicker the cloud, the brighter the color. Land surfaces show up as gray and ocean surfaces nearly black. There is a major limitation to visible imagery in that it is only relevent during daylight. | Get Last Visible Wavelengths Image 800 x 800 pixels |

Thermal IR| This type of image shows heat based radiation: the warmer the surface, the more infrared radiation it emits. For a satellite image, cooler surfaces are bright whereas warmer surfaces are dark. Since the atmosphere cools as you increase in altitude, clouds would show up as cool bright areas and land surfaces as dark areas. In addition, low clouds will be more gray and higher clouds will show up more white. As a result, tall thunderstorm clouds will show up as bright white and fog will be hard to decern from land areas. A large advantage of IR is that you can view it 24 hours day. | Get Last Thermal IR Image 800 x 800 pixels |

Water Vapour IR Wavelengths | | This is slight modification of the IR images which return an integrated amount of water vapor in the atmosphere especially weighted towards the upper atmosphere. Moist areas show up as white dry areas as black. Since jet streams carry large amounts of moisture with them, they generally show up as light gray streaks in this type of imagery. | Get Last Water Vapour IR Wavelengths Image 800 x 800 pixels |
