Understanding Albedo: The Earth's Reflective Shield is a measure of the diffuse reflectivity of a surface, specifically indicating the fraction of incident solar radiation that is reflected back into space. It is a dimensionless quantity expressed on a scale from 0 to 1 (or 0% to 100%): The albedo of a surface depends primarily on its

: A perfect reflector that bounces back all radiation. Earth's average albedo is approximately

On a global scale, Earth's average albedo is approximately , meaning roughly one-third of the sunlight reaching our planet is reflected away. Types of Albedo
