Albedo planet would drop to about 0 °C. In contrast, if the entire Earth was covered by water — a so-called aquaplanet — the average temperature on the planet would rise to almost 27 °C. For land surfaces, it has been shown that the albedo at a particular solar zenith angle "θ" can be approximated by the proportionate sum of two terms: the directional-hemispherical reflectance at that solar zenith angle, formula_1, and the bi-hemispherical reflectance, formula_2, with formula_3 being the proportion of direct radiation from a given solar angle, and formula_4 being the proportion of diffuse illumination. Hence, the actual albedo
Albedo One Albedo One Albedo One is an Irish horror, fantasy and science fiction magazine founded in 1993 and currently published by Albedo One Productions. "Albedo One" is widely regarded as the successor to the defunct Irish science fiction magazine "FTL", which was originally published by the (also now-defunct) Irish Science Fiction Association. "FTL" was itself a successor of the Irish magazine "Gateway". "Albedo One" is often credited as holding the position of the "longest running Irish magazine of speculative fiction" and has been billed as "Ireland's answer to "Interzone"." From issue 1, 1993, to issue 12, 1996, "Albedo One" was published
