The albedo of the Earth

Looking at the Earth from space we see a complicated mixture of clouds, snow, ice, water, tundra, desert, forest, jungle, farmland, and cities. The albedos of these surface conditions are different. To make things even more complicated, the appearance of the Earth is always changing. Snow falls and then melts. Clouds form and fade away. How can we figure out the albedo of the Earth? The best way is to measure the albedo from satellites in orbit around the Earth..

Looking at this picture, can you guess the albedo of the Earth?
