This app visualizes global climate data from satellites so you can view carbon monoxide, carbon dioxide, air temperatures, and water vapor levels. At the bottom are color-coded legends to show you how they vary around the world. The Earth can rotate 360 degrees, and you can zoom in and out with the swipe of a finger.
