GENERAL IDEA ON TEMPERATURE

EARTH ALBEDO The earth albedo involves scatting, reflection and absorption of solar energy. Definition; Earth albedo is the capacity of a surface to reflect the solar radiation/energy. Albedo is the ratio between incoming radiation and the amount reflected back into space expressed in percentage. In other words, albedo can be expressed as the ratio between the total solar energy (radiation) filling upon a surface and the amount reflected expresses as a decimal or percentage. For example the earth’s average albedo (including also albedo of the clouds) is about 0.4% (0.4% i.e. 4/10 of solar radiation is reflected into space). Therefore; temperature is markedly higher for a place with low albedo than of the place with high albedo. Land and water surface ferexample have quite different characteristics. Water has tendency to store heat that it receives while the land quickly returns (reflects) it to the atmosphere. On the other hand this experience, land has greater albedo or
