Water is very dark, almost black, which makes it much easier to see lakes or flooded lands. Notice how water and clouds in false-color images look very different than they do in true-color images. Depending upon how high they are and how cold they are, clouds' colors range from white, to baby blue, to bright turquoise. Ice and snow on the ground show up as bright turquoise. Cold things appear blue: the colder something is, the brighter blue it will look. By assigning colors (red, green, or blue) to measurements of infrared light, we can see and understand the resulting pictures - called "false-color images." In the false-color images available in NEO, areas with plants look bright green while deserts look tan. Scientists use satellite sensors to measure how much infrared light Earth reflects back up into space. Data is generally available within three hours of observation. Supports time-critical application areas such as wildfire management, air quality measurements, and weather forecasting. NASA uses satellites in space to gather images like these over the entire planet every day. Interactive interface for browsing full-resolution, global, daily satellite images. Infrared light is invisible to our eyes, but not to satellites. That's because the images include more than just the red, green, and blue light that our eyes can see, but also infrared light. The images might look a little funny, sort of like a TV picture that needs to be fixed. These images show Earth's surface and clouds in false colors.
