AccuWeather.com offers Standard Infrared satellite images for the entire world, including the United States. The term "Infrared" means that the satellite is detecting the temperature of the clouds. Standard Infrared satellites are grayscale; brighter clouds are colder, meaning higher and hence stronger storms.
An issue with this type of satellite is that it is difficult to see the small differences in the temperature of the clouds near the edge of the scale, and turning grey to white is sometimes not visible enough to the naked eye.
Rare night-shining clouds that glow across the edge of space tend to appear near Earth's poles. But since the turn of the century, these silvery clouds have become more frequent sights over lower latitudes.Read Story >
