Albedo

  • Glossary item | Last updated: 08 Aug 2023

The fraction of solar radiation reflected by a surface or object, often expressed as a percentage. Snow covered surfaces have a high albedo; the albedo of soils ranges from high to low; vegetation covered surfaces and oceans have a low albedo. The Earth’s albedo varies mainly through varying cloudiness, snow, ice, leaf area and land cover changes.
