Albedo in an albedo range of 0.1 to 0.4. The average albedo of Earth is about 0.3. This is far higher than for the ocean primarily because of the contribution of clouds. Earth's surface albedo is regularly estimated via Earth observation satellite sensors such as NASA's MODIS instruments on board the Terra and Aqua satellites, and the CERES instrument on the Suomi NPP and JPSS. As the amount of reflected radiation is only measured for a single direction by satellite, not all directions, a mathematical model is used to translate a sample set of satellite reflectance measurements into estimates of directional-hemispherical
Albedo 0.39 Albedo 0.39 Albedo 0.39 is a studio album by the Greek electronic composer Vangelis, released in 1976. It was the second album produced by Vangelis in Nemo Studios, London, which was his creative base until the late 1980s. It contrasts with his previous album, "Heaven and Hell", which was classically inspired and choral, while "Albedo 0.39" has blues and jazz overtones. It was his first Top 20 UK album. It is a concept album themed around space physics (the reflection of light i.e. physical truth). Its title is inspired by the idea of a planet's albedo, the proportion of the
