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 One by Tachyon Productions and was in an A5 size format. From issue 13, 1996, the magazine moved to a larger A4 format and was published by Albedo One Productions. The move to new publisher and format was motivated, according to the editors, "in an effort to gain better distribution, more advertising and put a little jizz into the magazine.". "Albedo One" currently publishes original (i.e. previously unpublished) stories from Irish, European and International authors.
