Albedo reflectance and bi-hemispherical reflectance (e.g.,). These calculations are based on the bidirectional reflectance distribution function (BRDF), which describes how the reflectance of a given surface depends on the view angle of the observer and the solar angle. BDRF can facilitate translations of observations of reflectance into albedo. Earth's average surface temperature due to its albedo and the greenhouse effect is currently about 15 °C. If Earth were frozen entirely (and hence be more reflective), the average temperature of the planet would drop below −40 °C. If only the continental land masses became covered by glaciers, the mean temperature of the
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
