WebData Documentation. Back to Glossary. Albedo (1) A ratio of the radiation reflected by a surface to that incident on it. Clouds are the chief cause of variations in the Earth's albedo since clouds have highly varying albedo, dependent upon thickness and composition. Old snow is about 55% (0.55), new snow around 80% (0.8). water surfaces vary ... WebFresh snow, on the other hand, can have an albedo of 90%, which means that 90% of the sunlight that hits a snow-capped peak is reflected out to space. The amount reflected back out to space is called the planetary albedo. It’s calculated by averaging the albedo of all Earth surfaces – including the land, ocean, and ice.
