  • Different surfaces, like forests and oceans, have varying albedos, affecting the Earth’s energy balance.
  • Urban areas tend to have a lower albedo due to darker materials like asphalt.
Meaning
The fraction of solar energy (light) reflected from the Earth back into space; it is a dimensionless value typically expressed as a percentage.
