Vangelis in his music track states that something, presumably the Earth has an Albedo of 0.39....

Albedo is the proportion of light that is reflected from a surface, so an albedo of 0.39  means that 39% of the light that hits the earth is reflected. It is frequency dependent but apparently if there is no frequency attached to the measurement then it is conventionally an average over visible light.
