Institute of Geographic Sciences and Natural Resources ResearchCASBeijing China 2. Graduate University of Chinese Academy of SciencesBeijing China AbstractSurface albedo is a critical consideration for energy balance at the land-air interface. It determines the allocation of radiant energy between the earth' s surface and atmosphere. Changes in surface albedo affect the energy balance of land-air systemwhich could in turn lead to climate change. Land Use /Cover Change LUCC is an important element of global climate change. LUCC affects surface albedoand thus climate change. Surface albedo is controlled by solar elevation angle land surface nature soil moistureweather conditionetc. This paper presents an in-depth review of the driving factors of surface albedo. Conventional observations of surface albedo are point-basedand therefore have limited spatial representation. On the other handsurface albedo retrieved by Remote Sensing RScould have a large spatial representation. HoweverRS-driven surface albedo needs validation by ground-truth observations. Hence this paper reviews and epitomizes observational and RS-based analyses surface albedo. It also summarizes research progress in surface albedo in relation to global climate. Moreoverthis review highlights the strengthsweaknesses and future directions of surface-albedo /climate-change research. The points documented herein could profoundly augment current understanding about global climate change and related driving factors. Key wordsglobal changesurface albedoluccremote sensing.
