Ice reflects 50% to 60% of incoming solar heat. Albedo is part of the energy from the sunlight that casts back into the atmosphere. These rays have a significant effect on our climate. When the albedo rises, the universe reflects light more and consequently, higher levels of radiation are sent back to space so the Earth cools down. General formula for Albedo: Stefan-Boltzmann equation: Combining the two: As mentioned above, I wanted to devise an equation that can relate the colour of a surface to the temperature on the surface. I tried using the general definition of albedo and combining it with the Stefan-Boltzmann equation (see above, Relevant Equations).A bond is a debt security that an entity secures from an investor at a fixed interest rate, while a debenture is a debt security that is obtained by a creditworthy reputation rather than through a specific asset.Its surface is covered by nitrogen, methane, carbon dioxide and water ices and has a high geometric albedo of more than 70%.
