This project is concerned with glacier and climate variations in the low latitudes, focusing on climatic forcing-response processes. Given the global nature of climate, interest is in the tropics as a whole, with a regional emphasis on East Africa. The project components include glacier area-change detection from satellite for selected mountains with suitable "ground truth"; ice volume-change detection from an areo-photogrammetric re-mapping of Mount Kenya's glaciers; a quantitative analysis of the various kinds of climatic forcing that have driven the changes of Lewis Glacier, Mount Kenya, from the latter part of the last century to the 1990's; and with lower priority, a comparative climatic forcing and retreat history of glaciers in New Guinea, East Africa, and the South American Andes. Overall, the project shall follow promising leads in the development of "tropical satellite glaciology" for climate purposes, in combination with the analysis of existing field observations, while requiring only limited field work. Particular attention shall be given to the quantitative evaluation of the climatic forcing of recent glacier changes that may be relevant to the "greenhouse" issue.

该项目关注的是冰川和气候变化， 低纬度地区，侧重于气候强迫-反应过程。 考虑到气候的全球性，人们对热带地区感兴趣， 一个整体，以东非为区域重点。 项目 组件包括卫星对冰川面积变化的探测， 选定的山与适当的“地面实况”;冰量变化 从肯尼亚山的航空摄影测量重新映射的检测 冰川;各种气候的定量分析 促使肯尼亚山刘易斯冰川的变化 从上个世纪后半期到20世纪90年代， 较低的优先级，比较气候强迫和撤退的历史 新几内亚、东非和南美洲的冰川 安第斯山脉。 总的来说，该项目应遵循有希望的线索， 发展气候“热带卫星冰川学” 目的，结合现有领域的分析 虽然只需要有限的实地工作。 特别 应当注意对下列各项的定量评价： 最近冰川变化的气候强迫可能与 关于“温室”的问题。
