Albedo distribution of solar radiation reaching the Earth's surface. These factors vary with atmospheric composition, geographic location and time (see position of the Sun). While bi-hemispherical reflectance is calculated for a single angle of incidence (i.e., for a given position of the Sun), albedo is the directional integration of reflectance over all solar angles in a given period. The temporal resolution may range from seconds (as obtained from flux measurements) to daily, monthly, or annual averages. Unless given for a specific wavelength (spectral albedo), albedo refers to the entire spectrum of solar radiation. Due to measurement constraints, it is often given
Albedo One "The Mammoth Encyclopedia of Science Fiction", notes that "Recent issues have boasted a printed cover, but the magazine still contains a black-and-white photocopied interior" and could "from the purely aesthetic point of view, benefit from some enhanced production values". The entry continues to note that "the editorial and literary quality of the contents more than makes up for this". However, Mann's inclusion of some genre magazines like "Albedo One" as opposed to other available magazines earned some criticism from reviewers, with one reviewer from the online edition of The Zone commenting that "Ireland's "Albedo One" rates a plug...
