ALT A visualization of data from one of two PREFIRE CubeSats. The base of the image is an illustration of the globe showing Greenland, with Iceland in the lower-right corner and the blackness of space along the top of the image. Positioned above Greenland, a multicolored X represents infrared data from multiple layers of the atmosphere that was gathered during several orbits over the area. A color scale in the upper-left corner shows that dark blue represents the lowest brightness temperatures and then ranges through light blue, green, yellow, orange, and red, which represent the highest brightness temperatures. The data in the X is primarily dark blue in the upper layers. Lower layers show variations of green, yellow, and orange, especially along the coastlines of Greenland.
