Abstract ATM-9631750 Jacoby, Gordon C. Columbia University, Lamont-Doherty Earth Observatory Title; Climate Change in Mongolia and its Role in Global Environmental Change This awards supports a paleoclimatic study in Mongolia. This is a remote nation which has only recently become accessible to western scientists, and from which there is paleoclimate information to date. Forests, particularly in montane regions, are largely undisturbed. Tree-ring analysis of samples from living trees and subfossil material is likely to produce time series of millennial length with annual and seasonal resolution. With samples from high -elevations and lower-elevation dry sites; tree-ring analysis will yield time series to reconstruct both temperature and precipitation respectively. These reconstructions will be important long-term climatic information from near the central portion of the world's largest continental region. The resulting climatic reconstructions and evaluations will make strong contribution to climate history of this important region to evaluations of climate change in Mongolia.

Jacoby, Gordon C.哥伦比亚大学Lamont-Doherty地球观测站Title；蒙古的气候变化及其在全球环境变化中的作用该奖项支持在蒙古进行的古气候研究。这是一个遥远的国家，直到最近才对西方科学家开放，并从中获得了迄今为止的古气候信息。森林，特别是山区的森林，基本上没有受到干扰。对活树和亚化石材料样本的年轮分析可能产生具有年和季节分辨率的千年时间序列。样本来自高海拔和低海拔干燥地点；树木年轮分析将产生时间序列，分别重建温度和降水。这些重建将是世界上最大的大陆区域中心附近的重要长期气候信息。由此产生的气候重建和评估将对这一重要地区的气候历史对蒙古气候变化的评估做出重要贡献。
