This geocolor image from the National Oceanic and Atmospheric Administration (NOAA) GOES-16 satellite captures the deepening storm off the East Coast of the United States on Jan. 4, 2018. The powerful nor'easter battered coastal areas with heavy snow and strong winds from Florida to Maine. Notice the long line of clouds stretching over a thousand miles south of the storm, which is drawing moisture all the way from deep in the Caribbean.
Geocolor is a multispectral product composed of true color (using a simulated green component) during the daytime, and an infrared product that uses bands 7 and 13 at night. During the day, the imagery looks approximately as it would appear when viewed with human eyes from space.
