Albedo is the proportion of insolation that is reflected back by the surface. It depends upon the nature of the surface upon which the solar radiation is incident and the angle of incidence of the solar beam.
The Thermosphere is located between 80 and 400 km above the mesopause. It contains electrically charged particles known as ions. It is therefore known as Ionosphere. The temperature here starts increasing with heights. Radio waves transmitted from the earth are reflected back to the earth by this layer. The International Space Station and other satellites orbit in this layer. Auroras are observed in the lower parts of this layer.
