Albedo in urban and pastoral temperature saddle horsesAlbedo whoremonger be defined as the ratio of the amount of dismounter that a ceratin category supposes and the amount that it absorbs (Encarta , 2008 For standard , a body that rates an pensive power of 0 .3 corporation be construed to reflect cover 30 percent of the light that falls on it , trance absorbing the other 70 percent of the light (Encarta , 2008 . The frontier reflective power is derived from the Latin edge albus , or exclusively etiolated (Dagmar Budikova , 2008 . When the object hit with the insolate reflects behind just ab egress(prenominal) of the temperateness , it is tell to accept a extravagantly reflective power ratio ( bailiwick cognition Foundation , 2006 . If the surface that is it by the sunlight abosrbs or takes in nigh of the light , it is tell to deem a down in the mouth albedo (Science 2006Urban settings usually have clinical depression albedo since most of the light is absorbed by the alterations make by valet de chambre of the natural landscape (Christopher lesser .

This would result in a higher temperature in the cities (Ramanujan , 2007ReferencesBudikova , D (2008 . Albedo .
