albedo, definition of

The fraction of the total solar radiation incident on a body that is reflected by it. Albedo can be expressed as either a percentage or a fraction of 1.

• Can Annual Irradiance = Annual Enthalpy? If So, What Does It Show About Climate Change
  This mathematical exercise was done to see how close calculated irradiance would come to measured irradiance and to prove that climate models using enthalpy instead of radiation or irradiation were valid.  (The CRGW (3) model is a enthalpy based model). ...

• BOMBSHELL: Study Reveals Climate Warming Driven by Receding Cloud Cover
  If climate science were a functioning scientific discipline rather than a priesthood, this paper would trigger a major course correction. It would cast doubt on the simplistic link between CO₂ and warming, redirecting focus toward cloud physics, ocean-atmosphere...
• James Hansen: Climate Cassandra or Science Salesman?
  Hansen’s argument structure is fundamentally circular: he assumes a high-sensitivity system, interprets ambiguous data to reinforce that view, and then treats the match as confirmation...
• The Continuing Albedo Change Warms the Earth More Than Twice as Much as CO2
  All life on Earth (somehow) originates from the Sun's heat. But how much of the solar irradiation reaches us Earthlings?
• Let it snow!
  Snow – those marvelous little crystals of frozen water that drift down from the sky – in gentle silence, in the fury of an artic-like blizzard, or in any and everything in between...
• An Unexplored Source of Climate Change: Land Evapotranspiration Changes Over Time.
  This Model was created to encourage scientist to collect the information necessary to determine the Earth’s ET change over time, the area of “special parcels”  and plume size.  This Model shows that this data is necessary for our complete understanding...
• More on Cloud Reduction.  CO2 is innocent but Clouds are guilty.
  Statistical uncertainty in the CERES and Cloud data seem to retard acceptance of alternative GW theories.
• Why do Earth’s hemispheres look equally bright when viewed from space?
  For years, the brightness symmetry between hemispheres remained a mystery.
• Where have all the Clouds gone and why care?
  By Charles Blaisdell PhD ChE The earth’s cloud cover has long been an important puzzle in climate change.  Cloud cover has many types and varies significantly from year to year. …

The ratio of reflected to incident light; albedo can be expressed as either a percentage or a fraction of 1. Snow covered areas have a high albedo (up to about 0.9 or 90%) due to their white color, while vegetation has a low albedo (generally about 0.1 or 10%) due to the dark color and light absorbed for photosynthesis. Clouds have an intermediate albedo and are the most important contributor to the Earth's albedo. The Earth's aggregate albedo is approximately 0.3.
