You Can Be ABCs by Robert White II5/30/2023 ![]() Since they reflect more near infrared than green, plant-covered land appears deep red. In this case, plants reflect near infrared and green light, while absorbing red. One of our most frequently published combinations uses near infrared light as red, red light as green, and green light as blue. Thermal infrared, usually shown in tones of gray to illustrate temperature.We use this to differentiate between snow, ice, and clouds. Blue (red), two different shortwave infrared bands (green and blue).Shortwave infrared (red), near infrared (green), and green (blue), often used to show floods or newly burned land.This is a traditional band combination useful in seeing changes in plant health. Near infrared (red), green (blue), red (green). ![]() Our four most common false-color band combinations are: Shortwave infrared light highlights the difference between clouds, ice, and snow, all of which are white in visible light. For instance, floods are best viewed in shortwave infrared, near infrared, and green light because muddy water blends with brown land in a natural color image. ![]() Though there are many possible combinations of wavelength bands, the Earth Observatory typically selects one of four combinations based on the event or feature we want to illustrate. ![]() How to Interpret Common False Color Images ![]()
