This is the standard definition version MPEG of the Cloud Albedo Animation.
Clouds greatly effect the earth's solar energy balance. Albedo, or reflectance, deflects a portion of the influx of solar energy from reaching our planet's surface. At the same time, a blanket of clouds insulates, preventing total loss of allthermal surface heat radiance out into space. This very important balance of energy is essential to our planet's ability to support life.
