Earth’s Energy Budget Introduction: This Albedo lab was created to help explain the process in which the Earth reflects solar energy back to space. The fraction of radiation reflected by an object is known as an albedo. In relation to the atmosphere‚ as solar radiation reaches certain colors on the surface of Earth‚ more radiation is absorbed by darker colors‚ which in turn decreases the solar radiation that reflects back to the atmosphere. If a person was interested in learning more
