The satellite images on this map are from the GOES 16 satellite. During daylight hours, imagery from the satellite’s red and blue channels are combined with the Near-IR or "Veggie Band". The "Veggie Band" is manipulated to approximate a green color. Combining each of these channels results in a near-perfect color image. During nighttime infrared imagery is used. You can see the transition as the sun rises and sets and the imagery switches.
