From Latin albus, white. Whiteness, reflected luminosity. In physics is the percentage of radiation that any surface, such as that of the earth, reflects in relation to the one it receives. In the albedo of our planet, now that we talk so much about climate change, many factors influence, such as the extent, inclination and coloration of the surface. The clear surfaces reflect more light and that's why they would heat up less. In our Andalusia most towns and cities dress in white.
